Sk. Azraf Sami — backend & applied-AI engineer
Software engineer building enterprise microservices and AI-powered products. Backend architecture (NestJS, FastAPI, PostgreSQL, API gateways and RBAC), full-stack React and TypeScript, and applied AI — retrieval-augmented generation, LLM agents, and speech and vision pipelines.
I work on the parts of AI products that are not the model — the queues, the retrieval layer, the guard rails, and the operational plumbing that decides whether any of it survives contact with production. Based in Dhaka, Bangladesh (UTC+6).
