I build end-to-end web applications, from polished user interfaces to robust servers and databases. I work on the frontend (React, Vite, JavaScript) and the backend (Python, FastAPI, Node.js). I design system architecture, databases and REST APIs, and integrate payment gateways, maps, messengers and email. I can add automation and intelligent AI modules so your service runs faster and more conveniently. I deliver well-documented, maintainable solutions and provide long-term support.
