Thaw Ecosystem — Platform & Core Maintainer

A macOS menu-bar manager built with Swift/SwiftUI alongside its cloud-native engineering footprint.

  • stonerl/Thaw: Own core features, reverse engineering, and release automation (CI/CD, signing, notarization) while testing compatibility for macOS beta releases.
  • thaw-app/platform: Manage entire organization governance, permissions, and environment gates via declarative Pulumi (IaC).
  • thaw-app/raycast-extension: Developed Raycast integration layer for deep-linking automation protocols and configuration hooks. Minor Contributions

Outside the terminal

  • 🙅 I cannot do LeetCode. I can ship to production, though.
  • ❄️ I use NixOS for gaming.
  • 🎮 The Witcher 3, CK3, Victoria 3, EU5—and an honorable mention for Forza Horizon 5 (and 6).
  • 🐺 I have a calupoh (wolfdog), ~50 budgies, and 6 agapornis.
