Builder by trade. Curious by default.
I like small tools, explicit systems, and software that earns its place. My work moves between product engineering, infrastructure, developer tooling, agents, games, and hardware.
The recurring stack is Elixir, Rust, TypeScript, Swift, and whatever best fits the problem. The recurring standard is simpler: make it useful, make it observable, and test the thing people actually run.

Writing from the work
- SQLite is an architecture decisionWhy a small database can be the system, not a placeholder.
- Test the binary you actually shipSource tests are necessary. The packaged artifact is the truth.
- Software for humans and agentsStable interfaces make tools useful to both.
