Problems I have worked on, how I approached them, and what happened.
A spot trading UI where every button press spends real money and nothing can be rolled back. Modelling the whole flow as an explicit state machine — including the state where hop one succeeded and hop two failed — turned a class of impossible-to-debug UI bugs into transitions I could name and render.
Custom Node + Canvas pipeline that turns a generated 240-frame MP4 into an ambient ASCII animation on the home page — a fraction of the bandwidth of a <video> tag, near-zero idle CPU, and fully theme-aware.
Developed a spot trading interface for Hyperliquid L1 with automatic route discovery, multi-hop execution, and an agent wallet pattern to bypass EIP-712 signing constraints.
Arkenia's first indexer re-read contract state on every event and exhausted an Alchemy free tier in three days. Rebuilding it around event-sourced projection — deriving state instead of asking for it — took per-event RPC cost to zero and let both mainnet and testnet contours run on the free public Base endpoint.
Shipped, but without a write-up — the scope is on the label.
Knowledge marketplace for AI agents — pgvector semantic search, payment webhooks, dispute arbitration, SSE event bus, CLI.
Hackathon build. The demo page runs on seeded data.
Twelve iridescent pixel-art loading animations for React in a single dependency-free file. Deliberately not an npm package.
