Marketer turned engineer. I build product systems, contribute upstream, and care about the small details.

• 🚀 Product engineering — I bring a marketer’s perspective to building software people want to use.
• 🌱 Open source — I dig into upstream code, reproduce edge cases, and ship focused fixes.
• 🏃 Long-distance mindset — I run a marathon every year.

• colinhacks/zod (#5856) — Stopped .merge() from silently dropping refinements; now throws like .pick() / .omit() / .extend().
• TanStack/query (#11364) — Added direct coverage for Subscribable, pinning down listener lifecycle, deduplication, state tracking, and bound subscribe behavior.
• TanStack/query (#11365) — Added direct coverage for Removable, pinning down GC defaults, timer scheduling, rescheduling, cleanup, and destruction.
• TanStack/table (#6215) — Fixed a NaN bug that left resized columns permanently stuck at 0 width.
• TanStack/hotkeys (#4) — Added hotkey conflict detection with four strategies: warn / error / replace / allow.
• adobe/react-spectrum (#9659) — Exposed isRequired in render props across DateField, TimeField, DatePicker & DateRangePicker.
• code-yeongyu/oh-my-openagent (#1794) — Fixed an OpenAI API error by teaching isGptModel() to recognize GPT models behind proxy providers.
