• Led the rebuild of the app’s settings system, replacing eight hand-built pages with typed setting lists that later categories also use, and rewrote its search to handle typos, accents and languages written without spaces.
• Built features from the interface to the Electron app: library sorting and search, saving the queue as a playlist, editorial album banners, and its first tray, menu bar and keyboard shortcuts.
• Built Cider’s current Google Cast support, first shipped to stable in July 2026 as an opt-in feature: a CastV2 sender in TypeScript and C#, TV playback with synced lyrics, and a permission flow that keeps Apple Music credentials off the TV.
• Refactored the audio engine’s effects chain, fixing Dolby Atmos compatibility, clipping and memory leaks; in the Windows app, stopped WebView2 from painting while hidden, released leaked audio sessions and fixed menus on high-⁠DPI screens.

* An estimate. Cider’s license server counts each license once, by a hash, when it checks in. Only copies on the newer service report to it, so Cider v3 from the Microsoft Store is not in the count. The Flathub figure is Flathub’s own count of installs since March 2022, not counting updates. To check it, select Downloads/Month on Cider’s Flathub page.

• SD-card CAN logging in Vector BLF format for the car’s ESP32-⁠C6 telemetry unit, with an allocation-free classifier that flags sessions containing faults or drive data, covered by software-in-the-loop tests that run on the host.
• Fixed a use-after-free in the CAN transmit path and out-of-bounds reads in the ESP-⁠NOW parser that were dropping live telemetry.
• One containerized CLI for the STM32 and ESP-⁠IDF builds (build, lint, DBC code generation, SIL tests, flashing), with CI on the same images.
• Every STM32 binary carries a post-link header with its commit, branch, size and CRC, so anyone can check which firmware is on the car.

• A transfer protocol with its own mDNS discovery, pinned mutual TLS, code-based pairing using a commitment scheme, and resumable uploads that are hashed while they stream.

A hobby project for now. I plan to open-source it once it’s ready.
