What I'm looking for

I’m looking to build production-grade AI-enabled backend and full-stack systems—RAG pipelines, reliable APIs, and secure AWS deployments—where strong CI/CD, testing discipline, and scalable modernization drive measurable outcomes.

I’m a Software Engineer with 6 years of experience building scalable backend systems, AI-enabled applications, and production-grade server-less Python services. I integrate LLMs and build RAG pipelines using vector databases, while developing AI workflow automation with OpenAI APIs and LangChain.

I’ve modernized enterprise platforms in event-driven microservices architecture, improving stability and CI/CD reliability while delivering scalable cloud solutions on AWS. Recent wins include increasing unit test coverage from 49% to 90% with Pytest and CI integration, upgrading Django and Ubuntu for long-term maintainability, and building Dockerized document intelligence pipelines and SLM fine-tuning workflows (Phi-3).
