What I'm looking for

I seek a senior frontend or engineering-lead role where I can drive performant, user-focused products, mentor engineers, and improve developer workflows.

I am a frontend lead with experience building generative AI platforms and cross-platform mobile apps, with a proven track record of improving performance, reliability, and developer workflows. I led frontend development at a YC-backed startup, built client SDKs, migrated complex canvas systems for high-performance rendering, and implemented comprehensive testing and monitoring pipelines.

I've shipped consumer-facing crypto and NFT products, implemented multi-wallet logins, real-time data updates, and native-to-Flutter migrations while managing CI/CD and performance optimizations. I focus on pragmatic engineering, measurable performance gains, and delivering polished user experiences.
