About Me

A developer who bridges data depth with modern AI

I am a certified database developer with deep expertise in Oracle PL/SQL, Python, SQL Server, and big data platforms. My career spans OLTP/OLAP systems, ETL architecture, healthcare compliance, toll processing, and ERP — across companies like JPMorgan Chase, Samsung, LG Electronics, and Ericsson.

What makes me different today: I do not just write code — I leverage AI tools to write better code, faster. At Bank of America I completed a rigorous 100+ hour AI/ML certification program and use GitHub Copilot every day to accelerate development, debug Python-to-database connectivity, and generate technical documentation.

I am based in Carrollton, TX and currently on assignment at Bank of America through Dexian. I am open to senior engineering and database architect roles where I can bring both deep legacy knowledge and modern AI fluency.
