Most recently, I was a *Senior Software Engineer at Eden*, where I co-authored *FastTelemetry*, an open-source Rust metrics library that replaced the OpenTelemetry SDK on our proxy after it became a bottleneck under millions of ops/sec. Thread-local increment is ~2 ns vs. ~40–400 ns for contended atomics on 16 cores. I also wrote an internal Rust logging library 3× faster than `env_logger`, built the Datadog dashboards the team runs on, and worked on a Redis-backed migration pipeline hitting 100 MB/s.
Before Eden, I spent *18 months at Bitwyre*, rotating through three teams. I built HFT and market-making systems in C++/Python over Kafka, WebSockets, and KDB+ for time-series market data, then designed core primitives for a Layer-1 blockchain that reached *50,000+ TPS* (CUDA-accelerated VM, DAG mempool, Tower BFT consensus). I also co-founded a side project, *ZeroBlock*, where I reduced a critical backend endpoint from 500 ms to 7 ms.
I care most about *systems-level Rust, performance engineering, and infrastructure that has to hold up under real workloads*. I'm equally comfortable in C++, C#, or full-stack TypeScript (React/Next.js/Express) when the problem calls for it. Comfortable working with senior engineers, and I've onboarded and mentored junior developers.
