What I'm looking for

I'm looking to build privacy, consent, platform, or distributed systems where I can improve compliance, performance, observability, and developer experience.

At Uber, I build privacy and consent systems that balance GDPR/CCPA compliance, performance, and user experience. I led PII masking, AI safety guardrails, privacy interfaces, and a mission-critical API delivering 95 ms P95 latency.

I’ve also improved engineering reliability through a modernization that raised test coverage from 35% to 95%, reduced production errors by 80%, and migrated around 400k lines from Flow.js to TypeScript. At PayPal, I optimized React and Node.js performance, SSR, caching, and GraphQL data consumption in a high-traffic platform.

Across ViRvii, Tradeweb, Sympla, Bume, and My Mixtapez, I’ve built APIs, streaming systems, cloud infrastructure, frontend architectures, and developer tooling using Node.js, Go, Python, TypeScript, React, Angular, AWS, and Terraform.
