From the Sunset District, San Francisco
I’m Tony, an SRE in San Francisco. Nights and weekends, I build software with a focus on privacy.
See what I’m building01 / About
I live in the Sunset District with my family and two Shiba Inus who have perfected the art of treating every request as a suggestion.
I’m training for an ultramarathon, and all the running gives me time to think up projects and work through how I might build them with AI. I spend nights and weekends turning those ideas into software.
I prefer software that runs locally, keeps dependencies to a minimum, and doesn’t track people.
A native Bitwarden and Vaultwarden client for iOS, iPadOS, and macOS. No third-party code in the runtime.
I reimplemented the crypto in Swift and check it against RFC vectors and weekly differential tests with the upstream C reference. Vault data stays encrypted on disk. On macOS, an ssh-agent signs git operations behind Touch ID.
A browser engine I’m building from scratch in Rust, from HTML parsing to layout and GPU rendering.
I test rendering against reference screenshots and document what each part of the engine supports. The repository is private for now, but I’m happy to walk through it.
An MCP server that gives AI models scoped access to Kubernetes clusters. Secrets are redacted by default, and destructive operations require human confirmation.
KUBECONFIG never leaves the local process. The project is still in progress.
An invite-only messaging app inspired by ICQ, with a buddy list and numeric user IDs. No phone number or address book required.
Use the hosted version, or self-host it in about fifteen minutes. The project is still in progress.
03 / Process
I’ve been trying different ways to use AI on these projects. Sometimes I have one agent write code and another review it. I’ve also had models interview each other to find questions I hadn’t thought to ask.
I started webber, my first browser engine, without much of a plan. Eventually I wrote strict specifications and started over with webber2. Having those written down gave me something concrete to check the code against.
