How to Add a Health Check to a Raid Workflow
Use the Raid `Wait` task to block on HTTP endpoints or TCP ports until a service is healthy — and pair it with `Group` for retry semantics on flaky deps.

Raid
Raid is a configurable CLI built in Go that orchestrates common development tasks, environments, and dependencies across distributed code repositories — driven by a single, declarative YAML profile.
It started as an internal script runner for a team I worked with at Workday, grew over a few years into something genuinely useful, and was rewritten as an open-source Go tool that's now approaching v1.0.
Notable design choices: declarative-over-imperative YAML, multi-repo as a first-class concept, agent-native via the Model Context Protocol (every command and resource is exposed to AI agents through the same surface a human uses), and opt-in telemetry with full transparency about what's collected.

Uppy
Uppy is a real-time multiplayer browser game where players tap together to keep a balloon in the air. A short per-player cooldown forces cooperation, a bird tries to pop the balloon, and difficulty scales with lobby size.
The interesting part is the backend: there are no traditional servers anywhere. Each lobby runs as its own Cloudflare Durable Object — consistent shared state for every connected client, WebSocket fan-out built in. Auth, scores, and profiles persist in D1. Magic-link login goes through Cloudflare Email Service. The whole thing deploys with a single wrangler deploy.
Built as a learning project for Cloudflare's edge platform — and as an excuse to ship something silly. Free to play, works on phones.

This Website
My personal website that showcases projects, hosts the blog where I write about engineering decisions in long form, and acts as the central place I direct people who want to understand how I work.
Built with TypeScript, React, Next.js (App Router), and Tailwind CSS v4. Long-form content lives in MDX alongside the code, not in a separate CMS. Hosted on Cloudflare Pages, instrumented with PostHog and Google Analytics. Open-source so anyone can fork it as a starting point for their own site.
