What I'm looking for

I'm looking to build production AI systems involving RAG, LLM orchestration, semantic search, evaluation, and enterprise knowledge workflows, while continuing to grow across backend engineering and machine learning.

At PBOPlus Consulting Services, I built enterprise RAG pipelines and multi-agent LLM orchestration for document understanding, improving knowledge-base response accuracy by approximately 40%.

I turn unstructured enterprise content into queryable knowledge using LangChain, LangGraph, ChromaDB, FastAPI, PostgreSQL, and OpenRouter APIs. I also built evaluation loops around incorrect responses, user feedback, and usage data to improve prompts, routing, and retrieval relevance.

My projects span fully local RAG assistants, Angular applications, and deep-learning network traffic classification that achieved 94%+ test accuracy and a 0.96 weighted F1-score.
