I lead a small team at Serviceware, shipping a .NET microservices platform serving 1M+ users across cloud and on-prem.
Outside work I'm chipping away at Spectra, a GPU-accelerated terminal in Rust, and dbfordevs, a database client that doesn't feel like a 2011 Java app. I always have a side project or two on the burner — it's where I experiment and learn new things.
