Backend Developer specializing in NodeJs APIs and AI Integration

Chi sono
I build secure, production-ready backend systems using Node.js, Express, and Fastify — REST APIs, auth flows, and AI-integrated features.
I focus on what's easy to get wrong: JWT auth with refresh token rotation, Redis rate limiting, and clean database design (MySQL, MongoDB, PostgreSQL). Recent work: a production auth API deployed on Render, Aiven, and Upstash, plus LogForge, an AI log intelligence platform.
I also fix backend issues in AI-generated apps (Lovable, Bolt.new, Replit). Pursuing a B.Sc. in Physics alongside. Open to freelance work, async-first.
