Searjasub Lopez

Senior Software Engineer

I build fintech, banking, and lending systems that run in production: React and TypeScript on the front, Node.js and Java services behind them, PostgreSQL underneath, and AWS around it all. Nearly six years in, I own features from design through production support and direct AI coding agents daily.
