Building

systems.

I like breaking complex problems down and building practical systems around them. Over 6+ years across application development, product engineering, and blockchain, I've grown from a hands-on developer into leading product architecture and engineering execution at Xyra Labs. My strength is building products from scratch: understanding the problem, designing the architecture, making the right technical tradeoffs, and driving it from idea to execution.

My background is mostly DeFi and blockchain infrastructure: smart contracts, wallets, DEX products, and trading systems. At Xyra Labs I built xyra.trade, a fully on-chain perpetual exchange. Lately I'm also building in AI around local models, evals, and open-source infrastructure. I care most about products that are technically deep and useful in the real world.
