Software engineer and open-source contributor interested in AI developer tools, coding agents, and developer productivity.

I like building small, reliable tools that make complex developer workflows easier to understand, debug, and trust.

I contribute to steipete/CodexBar, a macOS menu-bar app for tracking AI coding-provider usage.

My work spans provider quota visibility, billing semantics, subscription timing, diagnostics, and menu-bar reliability — with an emphasis on making multi-provider usage data understandable and testable.

• MiniMax provider: token-plan quota visibility, usage parsing, and regression testing.
• Billing semantics: failed-record filtering, local aggregation alignment, and reset-timing separation.
• Provider diagnostics: plan-title propagation testing and privacy-aware redaction.
• Menu-bar reliability: edge-case regression tests and snapshot preservation under network failures.
