About this gig

Want AI capabilities without breaking your backend architecture?


I am a Senior Backend Engineer & Full-Stack Developer with 7+ years of experience translating complex AI requirements into high-traffic microservices. I build highly resilient automation workflows, advanced semantic search engines, and secure backend APIs tailored specifically to your complex business rules.


WHAT I DO:

* AI/NLP: Custom multi-agent workflows using LangChain, OpenAI, LlamaIndex.

* RAG & Vector: Semantic search via Pinecone, ChromaDB, or pgvector.

* Microservices: Clean, testable APIs using Python (Flask/FastAPI) or Node.js (Express/NestJS).

* Database/Security: Advanced rate-limiting (Redis), messaging (RabbitMQ), secure inputs.


WHY WORK WITH ME?

* Production Code: Clean, dockerized codebases with automated test suites ready for cloud deployment.

* Clear Communication: As a mentor to 100+ devs, I easily explain technical limits to non-tech stakeholders.
