Leather at Trust Machines — an open-source, self-custodial Bitcoin & Stacks wallet. I played a key role in the Hiro → Leather rebrand, set up the monorepo and shared UI packages, and shipped Leather's first-ever mobile app in React Native — launched at BTC Vegas 2025, 1,850+ MAU within three months. Trust Machines is a venture studio backing teams building Web3 on Bitcoin; Leather and Granite are its flagship products.

Products I design and ship end-to-end:

• Stackr — a self-custodial cross-chain portfolio terminal (BTC · ETH · SOL · Stacks). Client-side, no backend, custom SVG charts. → case study
• SimplyFPL — a real-time Fantasy Premier League product, built solo. Edge-served on Cloudflare Workers + Durable Objects. → case study
• petewatters.ie — this site. An Astro PWA with build-time on-chain data (live GitHub graph + Solana-NFT avatar). → source
