I build on-chain trading systems. I joined Xyra Labs, then called Kana Labs, as a blockchain developer in 2022 and now run engineering there. I led the build of xyra.trade, an order-book perpetual futures exchange that runs fully on Aptos. Before that I built the Kana Paymaster, which sponsored gas for hundreds of millions of Aptos transactions.

Now

OpenVox. Private, fast, on-device voice dictation for macOS. Hold a key and speak, and the text lands at your cursor in any app. The speech models run on your Mac, so your audio never leaves it. Download for macOS.

Beyond OpenVox, I work on evals and open-source model infrastructure alongside the exchange.
