Senior Software Engineer & Tech Lead building AI-powered enterprise platforms at scale.

I love turning complex legacy systems into modern, intelligent platforms. Currently exploring how GenAI and LLMs can transform enterprise data workflows — and building the tools to make it happen.

01. About

I'm a Senior Software Engineer with 15+ years of experience building enterprise-scale systems across insurance, healthcare, financial services, and higher education.

Currently, I'm leading architecture and development of a large-scale data migration platform at a Fortune 500 insurance company — migrating 10M+ policies across 5,000 contracts from legacy mainframe to modern cloud infrastructure.

The most exciting part? I built an AI-powered chatbot using GPT-4 that enables teams to query complex data lineage in natural language — turning hours of manual investigation into instant insights.
