~/about

I build high-performance systems and developer tooling. Most of what I'm proud of sits at the boundary where hardware architecture meets WebAssembly and cloud compilers.

As a core contributor at OpenHW Studio, I authored over 550+ commits and 480k+ lines of code—engineering real-time Web Worker execution pipelines, WASM networking stacks (Wi-Fi/BLE), dual-layer compilation caching (<200ms latency), and automated netlist routing algorithms.

Whether emulating ARM Cortex-M microcontrollers in the browser or engineering hardware security keys with FIDO2 and TOTP on the ESP32-S3, I turn complex low-level specifications into reliable, lightning-fast software.

How I think about building.

No grand process — just a loop I trust: figure out what actually matters, ship the smallest real thing, put it in front of people, and tighten it from there.

how i build —

  • 1. find what actually matters
  • 2. ship the smallest thing that actually works
  • 3. put it in front of real users, fast
  • 4. measure → fix → repeat
so far, so good

I like a clean straight six.

Same way I like shipping — line it up, make clean contact, send it.

SIX!

Let's build something.

I'm looking for Systems & Software Engineering roles. If you are building low-level systems, developer tooling, or hardware simulators, let's talk.
