At Diya Interactive, I led architecture and backend development of a multi-tenant RAG knowledge platform that lets industrial and energy-sector engineers search OEM manuals and IOMs with page-level citations.
I engineered hybrid retrieval using query rewriting, agentic retrieval, pgvector and PostgreSQL full-text search, with results streamed over SSE. I also integrated Microsoft Foundry models and built a document-ingestion pipeline with OCR and deduplication.
On Diya Interactive's Security Workforce Management SaaS, I worked on backend services for scheduling, attendance, leave, compliance and notifications. I replaced in-process scheduling with Celery Beat and improved repeat bulk-schedule generation from about nine seconds to 0.06 seconds.
Earlier at KNYSYS, LLC, I built Python and Django backends and REST APIs for client workflows, and implemented asynchronous processing with Celery and Redis. At Bitrupt, I built React and React Native applications using Firebase and SQLite.
