GitBench

Free, open source, cross-platform Git client for Windows, macOS, and Linux with a custom GPU-accelerated UI — all your repositories, organized and a click away.

Built a native desktop app in C# / .NET 10 compiled with Native AOT, so it ships as a small self-contained binary with no runtime dependency
Rendered the entire interface with a custom GPU-accelerated UI framework instead of an off-the-shelf toolkit, with light and dark themes
Implemented core Git workflows on top of the standard Git CLI: visual commit graph, branch checkout/rename/delete/merge/rebase, inline diffs, staging by file or folder, stashes, worktrees, and submodules
Designed a multi-repository sidebar with collapsible folder grouping for instant switching between projects
Automated per-platform Native AOT builds via GitHub Actions and packaged releases with Velopack for one-click auto-updates from GitHub Releases

Taito 8080 Space Invaders Emulator

Taito 8080 arcade hardware emulator written in C# that boots Space Invaders, with a Svelte/WebAssembly browser frontend.

Implemented the full Intel 8080 instruction set, MMU, and I/O ports as a pure-C# core with no I/O dependencies, validated by CPU instruction tests
Modeled Taito-specific hardware quirks including the bit-shift register and interrupt timing required to drive Space Invaders
Compiled the core to browser-wasm and exposed the Machine API to JavaScript via [JSExport], publishing it as an npm package consumed by the frontend
Built a Svelte 5 + Vite frontend that renders the framebuffer to a canvas, wires audio and keyboard input, and supports drag-and-drop ROM loading
Wrote a Vite build plugin that fetches and assembles ROM binaries from a public CDN mirror at build time so ROMs are not committed
