What I'm looking for

I want to build reliable, scalable products where I can blend full-stack engineering with LLM/RAG workflows, improve performance with thoughtful APIs and data work, and support teams through testing, mentoring, and production-grade delivery.

I’m a Senior Software Engineer with 10+ years of experience building full stack applications, backend systems, APIs, and enterprise platforms across healthcare, logistics, finance, eCommerce, aviation, and AI-driven environments.

I’ve delivered end-to-end solutions using Python (FastAPI), Node.js, and React, including a Retrieval-Augmented Generation (RAG) system that lets users search, analyze, and interact with large volumes of business documents via natural language queries.

I also build secure, scalable backend services with Django and Django REST Framework (DRF), focusing on authentication, third-party integrations, and performance. In recent work, I optimized database tuning, caching strategies, and API enhancements, reducing average response times by 35% and improving scalability.

Across healthcare and enterprise teams, I integrated LLM APIs, prompt workflows, and RAG systems to improve data access and document handling, and I supported production with debugging, testing, deployment, and monitoring—always aiming for reliability, maintainability, and measurable outcomes.
