I build data- and API-heavy platforms on Laravel + React — and own them end-to-end. My focus is the parts most developers bolt on as an afterthought: interactive maps (Mapbox / Leaflet / Google Maps) and Meta / Google marketing-API integrations. 15 years, 50+ projects delivered, 100% Job Success. I work best on systems built to last and grow — but I'm just as happy taking a single, well-scoped task to start. ⚙️ FULL-STACK WEB PRODUCTS Laravel APIs paired with React frontends, built to last — not just to ship. From SaaS platforms and admin dashboards to a multi-brand CMS engine powering 15+ automotive dealer websites (Volvo, Mercedes-Benz, Alfa Romeo, Jaguar, Land Rover). 🗺 Interactive Maps — Mapbox / Leaflet / Google Maps API ◾ Custom maps: styled tiles, markers, plotting live data ◾ Map tools: drawing & editing shapes, measurements and calculations on the map ◾ Example: a solar-PV design tool with live roof mapping 🛠️ Meta Graph / Marketing API ◾ Lead capture: real-time leads delivered straight to CRM, email, or messenger ◾ Ad tooling: custom reporting logic, automated insights, campaign automation ◾ Publishing & analytics: posting to Instagram/Facebook (feed, stories), post & profile insights 🗃️ Google API ◾ Custom Looker Studio connectors ◾ Google Merchant Center feeds (recent project: 30k+ SKUs synced) ◾ Google Ads automation tools 💳 Payments ◾ Standard and custom Stripe / PayPal / Afterpay integrations However you want to start — a full build, a senior pair of hands on an existing codebase, or one focused task (a map feature, a Meta/Google API integration, a tracking or feed setup) — I'm easy to work with and quick to get going. Send a short note about your project, even a rough idea, and I'll tell you honestly how I'd approach it. 🤝 Thank you, Vitalii Komliev

I build, maintain, and refactor React, Next.js, and TanStack Start applications using TypeScript and JavaScript. For styling, I mainly work with plain CSS, Tailwind CSS, Vanilla Extract, and SCSS. Usually, my work is frontend-focused, but I’m equally comfortable handling full-stack tasks when the project calls for it. I regularly work with API integrations, authentication flows, data-heavy interfaces, and backend-driven systems utilizing Node.js, NestJS, or Supabase. Sometimes I join projects at the start and help build products from scratch. Other times, I step into existing codebases that have grown harder to maintain, scale, or extend. Over the years, I’ve worked on products where shipping features matters, but keeping the codebase maintainable matters just as much. As products grow, codebases naturally become harder to maintain. Features take longer to ship, bugs start showing up in unexpected places, and small changes can affect other parts of the system. I help make products easier to extend, more predictable to work with, and less painful to maintain over time. I try to keep things practical. Clear structure, reusable components, predictable state management, and avoiding unnecessary complexity so the codebase stays easy to understand as the product grows. I mainly work with TypeScript, React, Next.js, TanStack Start, Tailwind CSS, Vanilla Extract, Zustand, TanStack Query, Zod, shadcn/ui, and React Aria Components, and I’m comfortable working across modern React ecosystems. I also work with projects that were built quickly using AI tools like ChatGPT, GitHub Copilot, or other code generation tools and later became hard to scale or maintain. I help stabilize those codebases, improve structure, and turn them into something reliable. What I usually help with: ▪ Building React / Next.js applications from scratch ▪ Turning Figma designs into responsive, accessible UI ▪ Refactoring and improving existing React / TypeScript codebases ▪ Adding new features without breaking existing functionality ▪ Integrating REST APIs and GraphQL backends ▪ Improving performance in React / Next.js applications ▪ Handling complex frontend logic and state management ▪ Stabilizing AI-generated or prototype codebases I’m comfortable working independently or as part of an existing team. I care about keeping things practical, avoiding overengineering, and writing code that stays easy to work with for the people who maintain it later. If that sounds like what you need, feel free to reach out.
