Currently mainly focussed on building a client application with digital twin system and trainer / trainee situation in Unreal and any free time I'm working on my own big passion project in Unreal VR as well. Then on the side using claude to do vibe coding several progressive web apps and marketing and improving websites.

Working on AI chat implementation for DollarDeploy (platform to automate DevOps, kind of like Vercel for your own servers.

Neat thing about AI chat is that you can write in any language and it will automatically translate and use the right tools (create VPS server, build and deploy app).

https://crit.md - a CLI tool for reviewing AI coding agent output like a GitHub PR.

I got frustrated with Claude Code and Cursor producing plausible-but-wrong changes with no easy way to annotate and push back, without making a full PR. crit makes the review stage fun again!

Works on both plans as well as code itself. It’s been very rewarding hearing from folks who use it, everyone has been very kind! My most successful side project already :)

A browser flight game with vanilla Three.js and Tone.js: https://www.wingweave.org/

There's no engine, no physics lib, just a requestAnimationFrame loop and chill music.

The dev highlight so far has been 30 players in the first 48 hours and already having to sanitize racial slurs from the leaderboard smh.

If you still copy/pasting to GPT to correct / improve your text, I built a free macOS menu bar app that rewrites text in place across any application. Select text, hit Cmd-Shift-R, text gets rewritten instantly.

BYOK — uses your own Claude/OpenAI/Mistral API key, so text never touches a third-party server.

I'm building DRESSED (trydressed.com) — an AI personal stylist that builds outfit recommendations from clothes you actually own. You scan your closet once, and every morning it picks an outfit based on today's weather and your Google Calendar events. Client dinner on Tuesday? Different outfit than a WFH day.

I'm a senior SEO at Intuit with 25 years in search and zero engineering experience. I built the whole thing using Claude as my coding partner — React SPA, Netlify serverless functions, Supabase, Google Calendar OAuth, Stripe. The hardest part wasn't the code. It was figuring out that AI styling advice is useless without a database of what the person actually owns, which is a solved problem once you think about it that way.

Launching on Product Hunt next week: Wednesday, April 8.

I maintain a website about German bureaucracy. The bigger the website grows, the harder it is to keep track of certain facts.

I'm building a pipeline that monitors various sources for changing information, and creates a pull request or an email notification when something changes. For example, it triggers an update to constants.json if the income tax threshold (§ 32a EStG) changes. It sends a daily email digest of relevant discussions in relevant communities. The goal is to lighten my workload and improve the quality of the information I share.

This is my first coding project where I use AI. I use Claude Code on a tight leash to write the code, and ChatGPT's smallest model to extract numeric values from monitored pages.

The website: https://allaboutberlin.com/

The git branch: https://github.com/All-About-Berlin/aab/tree/ai (under /monitor)
