About
Performance is a product feature.
I build .NET systems, cross-platform applications, and developer tools with an emphasis on throughput, resilience, and clear APIs. My work spans hardware communication and embedded Linux, console rendering, storage engines, and build-time tooling.
At Elspec, that means improving waveform processing, resolving device-integration failures through physical hardware testing, and introducing the team's first unit and integration tests in CI.
Experience
Measurable improvements across product, support, and systems work.
