I build scalable frontend platforms and reliable real-time event data pipelines.
United StatesWhat I'm looking for
I've built scalable frontend platforms and real-time event instrumentation systems at Meta, Google, and PayPal. At Meta, I architected a TypeScript event framework capturing 500M+ structured client events daily and helped migrate four monolithic applications to micro-frontends.
At Google, I engineered modular React and Angular systems that enabled 20+ teams to deploy independently, built streaming analytics dashboards for 10M+ daily active users, and developed APIs handling 50K requests per second at 99.95% uptime.
At PayPal, I delivered responsive checkout experiences supporting $2B+ in annual payment volume, improved mobile load times by 50%, and built event pipelines supporting fraud detection and analytics. I care about performant mobile experiences, governed event data, privacy-conscious instrumentation, and dependable delivery across web and hybrid mobile applications.
