Message

At NITESUN TECHNOLOGIES, I lead development of SaaS and enterprise applications using Python, Django, FastAPI, React.js, and PostgreSQL. I delivered AI capabilities including LLM integrations, RAG workflows, and semantic search.

I also built responsive interfaces from Figma and optimized PostgreSQL schemas and queries, reducing query latency by 30%. I managed AWS infrastructure and automated CI/CD workflows with GitHub Actions and Docker.

Previously, at CODEIZ and MAVERICKS, I delivered multi-tenant SaaS platforms, APIs, and full-stack features. My work included integrating payment gateways and third-party APIs, implementing real-time functionality, and improving application performance.
