Senior Frontend Developer at Visa who built Angular micro-frontends and helped create an AI tool that cut root-cause investigations to hours.

At Visa, I built Angular and TypeScript features for a B2B payments platform, using standalone components, NgRx and Signals with Jest unit tests. I also helped rebuild the microservices-based platform that connects buyers and suppliers.

I was one of the engineers on an internal MCP-based AI tool for root cause analysis across 30+ repositories. I made its core independent of a single AI client, and the tool cut investigation time from days to a few hours.

At Visa, I served as Team Lead and Scrum Master while continuing to write production code. Earlier, I owned front-end delivery for fintech and web platforms at Strack Limited and Blunovation, working primarily with React.
