As a freelance full-stack developer, I design and deliver applications across the product lifecycle, from React frontends to Node.js and NestJS backends. I build REST APIs and integrate third-party services for clients with different levels of technical maturity.
At Fremitech, I worked on a cryptocurrency exchange platform, integrating CoinGecko’s API for real-time market data and addressing rate limits and data consistency. I also created dynamic charts and reusable interface components.
At Catreflex, I developed backend features and database models for real-time railway tracking, and deployed and maintained production services. At Galvitec, I integrated Zalando’s API to synchronize products and orders for e-commerce platforms.
