read in any order
Build deliberate,
see plate II for the index of capacities.
An index of
capacities.
Smart contracts
Solidity, Foundry, and a taste for audits. Written to be read twice.
DeFi protocols
AMMs, cross-chain liquidity, lending rails. Designed before they are deployed.
dApp architecture
React, Next.js, Wagmi, Viem, Ethers. Wallets as first-class citizens, not afterthoughts.
Front-end, carefully.
Type-safe, accessible, fast. Interfaces that stay out of the way of the product.
Creative surfaces.
Three.js, GLSL, bespoke typography. When a site should feel like an object.
Tooling & bots.
Long-running TypeScript services. PDF extractors, twitter agents, data pipelines.
Hackathons, won.
Fast prototypes that hold up after the demo. Three wins, two finalists, many late nights.
A steady temperament.
Small PRs. Small comments. Large context. Will argue with you when disagreement is the help.
Five rooms in which
I am most at work.
Colonnade of practice
The studio.
Client sites that feel bespoke. Long-form marketing pages, SEO-ready, hand-typeset.
The workshop.
dApps, wallets, on-chain integrations. Ship-ready code with receipts.
The forge.
Smart contracts and protocol logic. Foundry tests first, Solidity second.
The atelier.
Experimental surfaces — shaders, 3D, interactive type. Quiet, generative, personal.
The library.
Long-running bots, scrapers, analysis pipelines. The work that runs when no one is looking.
