Radion L.

Backend Developer | Python, FastAPI, MongoDB, Azure DevOps

Backend engineer working on LLM agents and research systems in Python — LangGraph multi-agent workflows, RAG, tool-calling, streaming chat — wired to data APIs, GraphQL, and vector search. Also prompts, LLM client infra, and batch pipelines. Before that I built APIs with Django and FastAPI, Celery workers for background jobs, and maintained data layers on MongoDB and Hasura/PostgreSQL. I care about clear data flow, readable business logic, and making sure what we ship actually works.
