At DevsOrb, I build FastAPI backend services and RAG-style retrieval pipelines integrating Anthropic Claude with Pinecone and pgvector. The pipelines improved relevance by 30%, and I also integrated OpenAI and PyTorch models into production.

At Next Horizon Digital, I developed production backend systems and embedding-based search that improved precision on top results by 20%. I’ve also contributed to projects including Clusivi, a fintech platform built from scratch, and Tia Works, an AI document intelligence platform using RAG and Anthropic Claude.
