Independent builder of software, interfaces, and useful tools.

Verifiable, signed receipts tying test and build results to a specific Git state. RunReceipt is local, cross-platform, agent-agnostic, and stores output hashes instead of sensitive logs.

npx --yes github:hehehe224/runreceipt#v0.1.0 run -- npm test

Built for code review, CI workflows, and coding agents that should leave durable evidence behind.

I take products from the first interaction decision through the system beneath it and the release path around it.

• Native: Swift, iOS product flows, mobile interaction design
• Web: TypeScript, JavaScript, React, responsive interfaces
• Systems: Node.js, Python, APIs, PostgreSQL, automation
• Delivery: testing, failure cases, CI, release tooling, documentation

The stack follows the problem. The quality bar stays put.

1. Document the constraint. Decisions are easier to trust when the tradeoff is visible.
2. Test the failure case. The awkward path is part of the product.
3. Make the first run easy. Useful software should not need a guided tour to prove its value.

Public repositories are where the ideas become inspectable: working code, honest constraints, tests, and documentation.

Make it clear. Make it real. Leave proof.
