About me

Full-stack developer (Node.js/TypeScript, NestJS, Next.js, PostgreSQL), based in Warsaw. I've been building backends and web apps for 3+ years. I currently work on a cloud developer platform similar to Supabase and Vercel: 700+ users, 1,000+ managed PostgreSQL databases, auth (OAuth, API keys), Stripe billing, an API gateway with Redis and RabbitMQ, and RAG with OpenAI and pgvector. I cut enterprise customer provisioning from days to under an hour. I also built XONAR, a headless store on Next.js and the Shopify Storefront API with a NestJS backend. B2B with VAT invoice. Polish B1, English fluent, Turkish native. GitHub: github.com/ataege
