Hi, I'm a backend developer. I build APIs, Data Engineering (ETL) services, and LLM-powered apps. I work mainly with Python/FastAPI, REST and third-party API integrations, PostgreSQL, Data Engineering, LLM Deployment, and RAG systems that answer questions from your documents. I also debug and clean up existing backend code. Before starting, I'll confirm scope, deliverables, and constraints so we agree on a realistic timeline. I write clear, maintainable code. Have a project? Message me the problem and the outcome you want, and we'll settle the approach first.
