Independent builder shipping AI products, developer tools, and native apps.

I turn everyday friction into focused software — from an English learning workspace
to subscription intelligence, a privacy-first macOS utility, and reusable tools for developers.

• Product first: start from a real workflow, ship the smallest useful loop, then learn from use.
• Local and private by default: keep data on-device whenever the product allows it.
• Native where it matters: use Swift/AppKit for macOS behavior and Tauri for lightweight cross-platform apps.
• Open by default: document the trade-offs, publish reusable parts, and make contribution paths clear.
