Undo

Filesystem safety net for the shell

Tracks what your last command did to the filesystem, shows you the diff, and rolls it back. Snapshots are taken before the command runs, so recovery does not depend on the tool that caused the damage. One Homebrew command to install.

Whook

Self-hostable webhook gateway

Durably capture, inspect, retry and replay inbound webhooks from a single binary. Every delivery is written to a write-ahead log before it is acknowledged, so nothing is dropped across restarts and a failed endpoint can be replayed hours later.

Qrshare

Laptop to phone in one command

Move files, folders, text or URLs across the local network by scanning a code printed in your terminal. No app on the phone, no account, no cloud hop. The transfer never leaves the LAN and the server shuts itself down when it is done.

Sched

Distributed workflow orchestration

A workflow engine in the spirit of Temporal and Cadence, without the operational weight. Workflows are ordinary Go functions; the engine handles durable state, parallel branches, retries and replay after a crash. Currently what most of my time goes into.

LLM Gateway

Cost-aware inference router

An OpenAI-compatible endpoint that routes each request to the cheapest model still meeting its latency and quality target. Semantic caching returns known answers without a call at all, and per-key rate limiting and cost tracking keep a team's spend visible.
