I've built production systems at Google, Uber, 0XPPL, and D.E. Shaw. At Google, I deployed an internal GenAI-powered onboarding tool that saves about three SWE weeks per onboarding cycle, and at 0XPPL I reduced P99 feed latency by 98%, from 15 seconds to 300ms.

I've developed high-throughput Go microservices, gRPC APIs, Django architecture, Web3 data systems, and Python compliance tooling. I also bring hands-on on-call experience, competitive programming strength, and compiler and FFT research projects in C++ and OCaml.

Redesigned the core Django feed architecture to resolve an O(N^2) fan-out bottleneck caused by complex Web3 wallet-viewer mappings. Implemented a pointer-based indirection layer and hot/cold data tiering, reducing P99 latency by 98% and enabling the platform to scale from 200 to 3,000+ users.
