À propos de moi
Need to fix a broken Python API, turn PDFs into a chatbot, or automate a manual workflow? I build with FastAPI, Flask, LangChain, LangGraph, PostgreSQL and Docker. With 4+ years in software engineering and production AI experience since 2024, I have worked on CRM agents, document extraction and travel search. I can deliver a focused bug fix, a document Q&A prototype or a scoped API integration, with tested source code and setup instructions. Message me with your goal, current stack and sample input so we can agree on scope and delivery.... Plus d’infos
