WORK
Six products and two extensions, plus the open source I keep alive. Each one built end to end: the contract or the manifest, the backend, the interface, the tests, and the release.
Live apps and protocols, built end to end.

2026 · BASEPAINT YEAR 3 HACKATHON WINNER, FOR COLLECTORS
A BasePaint profile for any address. Paste a wallet and see which daily canvases it owns and, the useful part, which days are missing from each set, which of those gaps are scarce, and what it painted. No wallet connect, no keys, no database: every number comes from BasePaint’s public indexer.
Judges: “Clean, simple and instantly useful to visualize and complete a collection.” Given away CC0 so it can fold back into BasePaint itself.

2026 · LIVE ON SOLANA DEVNET
Trustless peer-to-peer skill-wagering on Solana. Two players stake USDC on their own 1v1 match (Brawl Stars, Chess.com, Lichess), the result is auto-verified through the game’s API, and an on-chain escrow pays the winner. No house, no screenshots, no disputes. The contract has no instruction to ban winning players.

Two extensions published in the Chrome Web Store.
2026 · CHROME EXTENSION
Daily time budgets for the distraction sites you choose, enforced at the network level. Relaxing a rule costs a solved puzzle instead of a click, so the decision stays deliberate. Local-only: no accounts, no analytics, and no network layer of its own.

2026 · DEEPSEEK HARNESS PLUGIN
Billing season and account balance for the DeepSeek Harness web GUI. A pill in the composer statistics row, right after the native cache-hit reading, shows a peak or off-peak dot with a countdown to the next switch, and opens a panel that splits the balance into granted and topped up in the currency the API reports.
Listed in the community catalogs, including awesome-deepseekharness and the Harness Registry, which verified the manifest and the install.

2026 · DEEPSEEK HARNESS PLUGIN
A vendored, hardened fork of a community file explorer for the DeepSeek Harness web GUI: a file tree with a tabbed preview, search, sorting and in-panel editing. Every path, reads included, is confined to a registered workspace root, and external programs launch argv-only.
