How we deliver at Vasilkoff
We ship production software with small senior teams. Work typically starts with a short discovery to confirm scope, risks, and constraints, followed by the first milestone. For well-defined work we use fixed bids; for evolving products we run time-and-materials with weekly planning and transparent reporting.
Stacks and platforms
We build on Next.js/React and Node.js for the web, Flutter or native Swift/Kotlin for mobile, and WordPress where it makes sense (including headless or performance-tuned setups). Data is usually PostgreSQL or Firebase/Firestore. We deploy to Vercel, AWS, or GCP with CI/CD, environment isolation, and IaC where needed.
AI in real products
We integrate AI where it moves the needle: conversational support, internal tools, workflow automation, and retrieval-augmented knowledge. Our SmartAIChats work shows how to add GPT-powered help that actually reduces response time and increases conversion while keeping secrets safe and prompts versioned.
Web3 when it’s useful
We design and audit Solidity contracts and build full-stack DApps on EVM chains. SMRT16 demonstrates transparent on-chain revenue sharing and referral logic you can stand up quickly and operate at low cost.
Security and compliance
Least-privilege access, managed secret stores, scoped service accounts, and auditable pipelines. We separate staging and production, review dependencies, and document data flows. NDAs and DPAs on request.
Observability and SRE basics
We put simple, effective telemetry in place: uptime and error tracking, latency budgets, crash-free mobile sessions, and a small set of SLOs that map to business goals. Weekly reports show incidents, fixes, and trendlines.
Handover and support
Handover includes source code, infra access, runbooks, environment variables, deployment scripts, and a recorded walkthrough. Post-launch we offer SLA-based support or a monthly retainer for maintenance and small features.

Expert Answers to the Questions That Matter
Speed is great, but accountability is what protects your business. AI can help generate code and automate tasks, yet it cannot own deadlines, quality, or production risks.
That responsibility still lives with humans. We build with AI, but we stand behind the outcome, including free bug fixing and long-term support.
If you need guarantees and a team that owns delivery, responsibility must be a core part of the partnership.
We use local LLMs that run on our own machines and keep client data off third-party services.
We sign strict NDAs from the very beginning and follow clear data handling protocols throughout the project lifecycle.
The result is AI-assisted delivery without compromising privacy or ownership of sensitive information.
Timelines depend on scope, but as a practical guide: a professional business website typically takes 3–6 weeks from brief to launch. A mobile app (iOS + Android) with a backend is usually 8–16 weeks for an MVP. Custom web applications with integrations range from 6 weeks to 4 months depending on complexity.
Pricing is project-based or team-based depending on what you need. For a defined-scope project (a website, an app, a specific feature set), we quote a fixed price after a brief discovery call so you know the number before committing. For ongoing work or team extension (outstaffing), we work on a monthly retainer based on the seniority and hours of the engineers involved.
AI-accelerated delivery means we move faster than traditional timelines without cutting corners: the speed comes from tooling and process, not from skipping reviews or testing. All projects include a lifetime free bug-fixing guarantee on delivered code, so the price you see is the price you pay, with no surprise maintenance invoices for issues that were ours to fix.
Three things separate us from most agencies: we take direct responsibility, we use AI to deliver faster without sacrificing quality, and we stay involved after launch.
Direct responsibility means a named engineer owns your project, not an account manager who relays messages to an offshore team you never meet. When something goes wrong, you talk to the person who built it. This is why we offer a lifetime free bug-fixing guarantee: we stand behind the code we ship.
AI-accelerated delivery means we use local LLMs, code generation, and automated testing in our own workflow to ship faster: we have built these tools ourselves and use them on every project. That speed benefit goes to you in shorter timelines and more competitive pricing. And staying involved after launch means we do not disappear after payment: we offer long-term support, iterative improvements, and a development partner relationship that grows with your business.
AI and machine learning create measurable efficiency gains when they automate one specific, repetitive workflow end-to-end, not when "AI adoption" is treated as the goal itself. The clearest return comes from replacing a manual, time-consuming task with a pipeline that runs continuously without a person triggering each step.
We've built this for clients directly: Jarvis, an n8n-based AI assistant that analyzes Google Meet transcripts with GPT-4 to generate structured meeting summaries and action items automatically. For a real estate client, our Automated Sales Workflow captures Instagram leads and sends smart, context-aware replies without a human in the loop. Our AI-Powered Trend & Content Workflow uses n8n to detect emerging trends and publish content across social platforms automatically.
The pattern across all three: identify one high-volume manual task, automate it fully, and measure the hours saved. That's where AI and ML turn into real revenue and cost benefits, not just a slide in a strategy deck.
At Vasilkoff, we prioritize the privacy and security of our clients' data as an integral part of our AI solution development process. We adhere to strict data handling protocols that align with industry standards such as GDPR, HIPAA, and other relevant frameworks. Our team regularly undergoes training to stay updated on the latest data protection regulations and best practices.
We implement comprehensive security measures, including data encryption, secure access controls, and regular security audits, to ensure that all AI solutions are fortified against unauthorized access and breaches. Our solutions are designed with 'privacy by design' principles, ensuring that data privacy is an integral part of the mobile apps and web-development lifecycle, not an afterthought.
Furthermore, Vasilkoff engages in transparent data governance policies, making sure that our clients are fully informed about how their data is being used. By working with reliable AI technologies and maintaining open communication with our clients, we strive to build AI solutions that not only enhance business operations but also safeguard sensitive information and maintain user trust.
Yes, we are Cyprus-based and work with local businesses across Limassol, Nicosia, Larnaca, and Paphos. In-person meetings are available when they are useful: for discovery sessions, project kick-offs, or reviews where a whiteboard beats a video call.
We have built production websites and apps for Cyprus law firms, real estate agencies, car rental businesses, and consumer apps, so we understand the local market, the .com.cy landscape, bilingual (Greek/English) content requirements, and Cyprus-specific payment and compliance considerations without needing to learn them on your project.
That said, we also work with clients globally on a fully remote basis. Being Cyprus-based is an advantage for local clients who want a partner in the same timezone and business environment. It is not a limitation on the type or scale of work we take on.
At Vasilkoff, we understand that the cornerstone of any digital product is its user experience (UX) and user interface (UI). By integrating AI-driven insights, we can significantly elevate the design process. AI tools analyze user data to provide actionable insights on user behavior, preferences, and pain points. This data-driven approach enables our designers to create more intuitive and personalized user experiences that resonate with the target audience.
Our AI-driven approach to UI/UX design not only includes personalization but also predictive design, where the interface adapts to user actions and provides suggestions or actions preemptively. This anticipatory design can greatly enhance user satisfaction by reducing friction and making the user journey smoother and more intuitive.
Moreover, Vasilkoff's expertise in AI allows us to implement advanced techniques like A/B testing at scale, real-time user feedback analysis, and automated usability testing. These techniques ensure that designs are not only based on best practices but are also continuously evolving with the users' needs, leading to a more dynamic and engaging user experience.
The right choice depends on what the app actually needs to do, not a general preference for one technology.
| Native (Swift / Kotlin) | Flutter (cross-platform) | |
|---|---|---|
| Best for | Complex interactions, intensive graphics, deep device access | MVPs, uniform functionality on iOS & Android, tight timelines |
| Codebase | Separate iOS + Android codebases | Single codebase for both platforms |
| Performance | Highest: full native access | Near-native, sufficient for most business apps |
| Typical timeline | Longer: two platforms to build | Faster: one build ships to both stores |
| Cost | Higher: two platform builds | Lower: one codebase to build and maintain |
We've shipped both: CalculatorX (HideX), a Swift privacy vault app, went native for full device-level security access, while Voice VPN and AccuLevels went Flutter to ship on iOS and Android from a single codebase. We'll recommend whichever fits your actual requirements during a discovery call.
Vasilkoff employs a comprehensive approach to smart contract development, prioritizing security, efficiency, and customization. Initially, our process involves a detailed understanding of your business requirements, ensuring that the smart contracts are precisely aligned with your operational needs. We consider the unique aspects of your business to ensure that the smart contracts will perform as expected in real-world scenarios.
To ensure security and efficiency, Vasilkoff invests heavily in rigorous testing procedures. We write extensive unit and integration tests to cover all possible execution paths. Beyond internal audits, we advocate for and facilitate third-party external audits to provide an additional layer of scrutiny, enhancing the security of the smart contracts. The use of automated tools and AI assists in identifying potential vulnerabilities and optimizing contract efficiency, further bolstering the robustness of the contracts.
Our AI-assisted tools analyze the smart contracts to optimize gas usage and performance, reducing operational costs. By integrating these practices, Vasilkoff ensures the delivery of smart contracts that are not only secure and efficient but also cost-effective and reliable, providing our clients with peace of mind and a competitive edge in their respective markets.
Vasilkoff specializes in advising SMEs on best practices for measuring the return on investment (ROI) for new software technology implementations. Our approach emphasizes the importance of setting clear objectives and benchmarks prior to the deployment of any new system. This includes defining key performance indicators (KPIs) that align with business goals, such as increased revenue, cost savings, customer satisfaction, or operational efficiency.
To measure ROI effectively, we guide businesses through a process of quantifying the benefits of the technology, which may encompass enhanced productivity, reduced operational costs, or increased sales. We then contrast these benefits with the total cost of ownership, including initial investment, training, maintenance, and any incremental costs.
Additionally, Vasilkoff encourages a long-term perspective when assessing ROI. While some benefits may be immediate, others, like customer loyalty or brand reputation, may accrue over time. We also consider qualitative benefits, such as improved data insights or competitive advantage, which may be more challenging to quantify but are equally critical to business success. Vasilkoff's expertise lies in tailoring these measurements to fit the unique context of each SME, ensuring a comprehensive and realistic assessment of technology ROI.
The right choice depends on whether you want a managed outcome (outsourcing) or managed capacity (outstaffing).
| Outsourcing | Outstaffing | |
|---|---|---|
| You get | A finished product for a defined scope | Dedicated engineers who work under your direction |
| Who manages day-to-day work | We do: you review milestones | You do: full control over workflow |
| Best for | Clear brief, fixed budget, no desire to manage developers | Ongoing capacity, scaling a team without full-time hiring overhead |
| Pricing | Fixed price after a discovery call | Monthly retainer based on engineer seniority and hours |
Many clients start with an outsourced project and move to an outstaffed model once they see how the team works. Our dedicated guide to the difference, including cost comparisons and when each model breaks down, is at our outsourcing and outstaffing page.
Integrating AI technologies such as OpenAI's GPT can transform your business by providing a level of customer interaction that is both personalized and scalable. AI chatbots powered by advanced models like GPT can handle a vast array of customer queries in real-time, delivering prompt and accurate responses that can significantly enhance customer satisfaction. This integration means customers can get the information they need when they need it, without the wait times associated with human operators, leading to a more efficient customer service operation.
Beyond customer service, AI integration can streamline a variety of business operations by automating routine tasks, analyzing large volumes of data to glean insights, and optimizing decision-making processes. For instance, GPT can assist in drafting and summarizing reports, managing emails, and even generating content for marketing campaigns, freeing up human resources to focus on more strategic initiatives. This shift can lead to cost savings and operational efficiencies that boost your business's bottom line.
The strategic implementation of AI technologies also paves the way for enhanced product and service offerings. With the ability to learn from customer interactions and preferences, AI can help personalize the user experience. This tailoring not only improves engagement and loyalty but can also provide your business with valuable data on customer behavior and trends, enabling you to make informed decisions that drive growth and innovation. Vasilkoff specializes in harnessing these AI capabilities to create powerful solutions that propel businesses forward.
In the landscape of AI, open-source models provide a valuable alternative to proprietary solutions like those offered by OpenAI. Models such as LLaMA 2, OpenLLaMA, Falcon, Dolly 2.0, and MPT are becoming increasingly popular for their robust capabilities in natural language processing and generation. Vasilkoff's expertise lies in identifying the right open-source model that aligns with your business needs and goals. We assist in deploying these models to leverage their capabilities for tasks ranging from text generation to complex language understanding.
For businesses looking to integrate AI-driven image-to-text capabilities, open-source models like 'nlpconnect/vit-gpt2-image-captioning' and Salesforce's 'blip-image-captioning-large' are commendable options. These models are trained to convert visual content into descriptive text, enhancing accessibility and enabling new avenues for content interaction. Vasilkoff aids in customizing these models for specific use-cases, ensuring they are finely tuned to your operational context and deliver optimal performance.
Furthermore, Microsoft's 'trocr-large-printed' and 'trocr-base-handwritten', along with Google's 'pix2struct-textcaps-base', demonstrate significant advancements in the OCR (Optical Character Recognition) field. Vasilkoff can integrate these into your systems to digitize handwritten or printed text, streamlining data entry and archival processes. With our guidance, these tools can automate and enhance workflows, making information retrieval swift and error-free. Our team ensures seamless integration and provides ongoing support, empowering your business with AI while maintaining full control over the technology.
The AI trend that actually changes P&L for most businesses right now isn't generative chat. It's workflow automation: connecting AI models to your existing tools (CRM, inbox, social channels) so tasks complete without a person triggering each step.
We build this with n8n and local LLMs rather than only wrapping a third-party API: smrtAI is a free, easy-to-install AI LiveChat widget we built for websites, and SmartAIChats automates first-line support and lead capture for clients.
Privacy-preserving AI (running models locally instead of sending every request to a third party) is the trend enterprise clients ask about most in 2026. For many, it's a compliance requirement, not a preference, which is why we run local LLMs on our own machines for client work (see our answer on AI and data privacy above).
Blockchain earns its complexity when a project genuinely needs decentralization, transparent transaction history, or programmable ownership, not as a default choice. We assess this case by case against transaction volume, decentralization needs, data security requirements, and smart contract potential, rather than pushing every client toward a smart contract.
Where it fits, we've shipped it: SMRT16, an open-source Polygon DApp with automated referral earnings; NFTTRX, smart contracts securing intellectual property via NFTs; SendCrypto, a Web3 payment product on Polygon for P2P and P2B transfers; and Bella Chess, a cross-platform chess app combining AI training with NFT collectibles. Our fintech and Web3 work was also recognized with a BOC Hackathon Fintech award.
If the analysis doesn't clearly justify the added complexity, we'll tell you a traditional database and payment rail is the better call for your case: a recommendation against blockchain is still expert guidance.
