About
I am a backend-focused full-stack engineer with 4+ years of remote professional experience and programming foundations going back to 2016. I build production APIs, admin systems, mobile app backends, AI chat/RAG services and third-party integrations for small teams and client products. My strongest stack is NestJS, Node.js, TypeScript, PostgreSQL, TypeORM, AWS, Redis/BullMQ, Next.js, OpenAI and Pinecone. I prefer backend ownership, but can also ship frontend, Web3 and AI-enabled product work when the product needs it. Best fit: founders, agencies and small remote teams that need one reliable developer to take ownership, integrate systems and ship.
