Hi, I’m Anton - a Fullstack JavaScript/TypeScript engineer with 20+ years of programming experience and over a decade of production Node.js development. I build scalable backend systems, real-time web applications, and interactive browser experiences that are designed to last - not just to “work for now”.

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
