What I'm looking for

I'm seeking a fully remote AI backend engineering role with a US-based company, where I can build production RAG pipelines, vector search, and LLM-powered APIs.

I've built Python backend features and REST API integrations at Bista Solutions Inc. for 13+ enterprise ERP systems serving 1,000+ users across the US, UAE, and EU, improving operational automation by 40%.

I lead Odoo module migrations from v15/v16 to v18, refactoring deprecated logic and supporting production deployments across multiple time zones. My backend work includes PostgreSQL optimization, async APIs, REST design, and integrations with UPS, FedEx, DHL, and eBay.

I also built DocQuery AI, a production-grade RAG document search and Q&A system with document ingestion, semantic chunking, sentence-transformers embeddings, pgvector similarity search, and HuggingFace Transformers.

I'm transitioning into AI backend engineering, bringing 3+ years of Python experience along with FastAPI, Celery, Redis, async SQLAlchemy, Docker, and strong problem-solving experience from 2,000+ competitive programming problems.
