Products, systems, and tools made with care.
Case studies across operating systems, self-hosted infrastructure, developer platforms, game development, and published optimization research. Each one is grounded in working software or a verifiable research artifact.
case studies
- GenOS A Rust operating system from bootloader to desktop ↗2026A from-scratch x86_64 operating system with its own UEFI loader, no_std kernel, isolated userspace, capability-based file access, scheduler, and native framebuffer desktop.
- Overseer Self-hosted command center for every machine ↗2026One self-hosted control plane for Linux, macOS, and Windows: live terminals, coding agents, files, health telemetry, safe updates, and an MCP server in a single Go binary.
- OpenCel A self-hosted deployment platform ↗2026A Vercel-inspired deployment system you can own: connect GitHub, build on push or pull request, create preview URLs, promote releases, manage secrets, and inspect logs.
- The Hollow Icon Hopeful dark-fantasy life-sim action RPG ↗2026A Unity 6 RPG where a restorer hunts the improperly dead, rebuilds a mountain bastion, and chooses whether to heal corruption or wield what it remembers.
- TIDY UP! A complete co-op Roblox party game ↗2026Tiny players sort toys across a giant bedroom while lava rises—an immediately readable cooperative loop backed by server authority, persistent progression, live-ops hooks, and touch-to-gamepad controls.
- Applied optimization Research tooling behind two peer-reviewed papers ↗2022Reproducible instance-generation and validation tools for photo-slideshow and urban traffic-signal optimization, developed alongside two published metaheuristics studies.
