What I'm looking for

I want to build scalable, secure backend systems in Agile teams and ship AI features using LLMs, RAG, and vector search. I’m looking for continuous learning, strong engineering standards, and measurable impact on reliability and performance.

I’m a results-driven Software Engineer with 2+ years of experience building and maintaining Python backend systems, APIs, and database solutions. I’ve migrated legacy JSP-based applications to Python APIs with 100% feature parity, cut defects by 25%, and improved reliability with automated unit tests (99% code reliability) that reduced manual QA by 60+ hours per release cycle.

I also enjoy turning complex data into useful AI experiences—building a RAG-based Intelligent Document Query Platform with LangChain, FastAPI REST APIs, vector embeddings, and LLM-powered question answering. I’m comfortable optimizing SQL (including SQL Server) for performance gains (30% execution-time and latency reductions), following PEP-8, and working in Agile environments while continuously learning modern AI technologies.
