Project I'm proud of

zink

Transpiler between WASM and EVM, babysitting every byte, challenging things people think are impossible. The proc-macros explain my thinking about how programs should be developed and the asm emitter is smooth like butter. The failure point is that I didn't build my own IR, which finally limited it at function boundaries in high-level usage.

What I'm looking for

  1. Open source is preferred.
  2. Taking responsibility for a specific part of a system, or doing the architecture of new systems.
  3. Full stack or frontend work only if I'm the designer as well, or paired with a designer who understands the tech. Best if the role talks to users and collects feedback — I don't want to develop blindly.
  4. Open to all industries, because all of them are integrated or integrating AI.
