I'm an experienced full stack software engineer with a passion for AI, UX and cybersecurity.
I've spent the last 2 years creating Applied AI libraries and apps, most notably herdctl, Paddock and Local Review.

Stuff I've been working on lately
It is faster to generate lots of code than it is to read, understand, push back on or approve lots of code. The balance of effort is shifting hard toward the review side - so I built Local Review, a GitHub-style PR UI for the stack of commits still sitting on my laptop.
Paddock now runs on your own machine with one command, opens on the Claude Code history you already have, and tells you exactly which parts of your ~/.claude it is and isn't touching.
Paddock is a thin wrapper around Claude Code that runs it on a server and gives it a web UI — persistent, resumable chats you can reach from any laptop or phone, with forking, sub-agents, file sending and schedules on top. Here's why I built it and how it works.
I justed added support for Composable Fleets to herdctl. As I build herdctl into more projects, I increasingly find myself creating a fleet of agents per project, and wanted a way to run them all from a central place so that I can juggle a bunch of things at once.
herdctl makes it really easy to run agentic workflows on a schedule. One of the first such workflows I added to herdctl itself was a daily security audit. This has been running for a few weeks now, so I wanted to share some early results.
TypeScript, AI, React and NextJS
herdctl is an open-source orchestration layer for Claude Code that enables autonomous AI agent fleets. Define agents in YAML, trigger them on schedules or chat messages, and let them work through GitHub Issues, Jira, or Linear autonomously. "Kubernetes for AI agents."

mdx-prompt lets you use JSX to write LLM prompts, giving you the familiarity of React and the power of composability, templating logic, testing and reuse that come from JSX & MDX.

bragdoc.ai is a SaaS application that uses a blend of AI and traditional SaaS technologies to help professionals keep track of all the great work they've done, and automatically generate high quality, evidence-based weekly summaries for your boss or performance review documentation to support your next promotion. It's also completely open source. I blog about it often.

Local Review is a GitHub-style pull-request UI for the stack of commits already on your machine, before any of it is pushed. A coding agent writes a dozen tidy commits in an afternoon; Local Review shows every one of them as its own PR, grouped into the colour-coded stacks you mean to open, across one repo or several. You comment, your agent reads the comments out of plain YAML files and replies in the same place, and when a stack is right it goes up as GitHub native stacked PRs. It's read-only on your repos, never talks to GitHub, and only listens on localhost. npx local-review.

Paddock is browser tabs for Claude Code. Before tabs, every page needed its own window; Claude Code is at that stage now — one session per terminal, on one machine. Paddock is the tab bar: an open-source, self-hosted home for all your Claude Code chats, persistent and resumable from any browser, and sorted into projects once there are too many to keep track of. Chats can run on their own via schedules and event triggers, background work outlives the turn that started it, and an external Management API lets your other tools drive the whole instance over MCP. Built on herdctl.

react-auto-intl uses AI to automatically internationalize and translate your React and Next JS applications. It can reduce days of tedious work to minutes.
Find out moreI've been writing JavaScript, HTML & CSS for 20 years. Along the way I've gotten good at UX, AI, IaC and CI/CD. My go-to's are TypeScript, React and Prisma, CICD'd to the cloud.
I've deployed large scale applications to AWS and Google Cloud, using terraform, kubernetes, and docker to create scalable architectures from the ground up using CI/CD and IaC.
I'm fluent with GitHub and GitLab CI/CD pipelines, and know how to get my code into production quickly and with high quality.
I've been programming with JavaScript since long before it was cool to do so. These days I'm a TypeScript fanboy, but I still love JavaScript. I'm also a big fan of React, Next.js, and Tailwind CSS.
I've also been written my fair share of Python, mostly using it for AI projects. I've used C++ for some embedded systems work, and hate Java. Well, dislike anyway.
