Projects & interests

A few projects where product thinking meets family, community, and the joy of making things useful.

Game

Watt Fighters

A velodrome racing game for riders on smart trainers and power meters: match sprint, keirin behind the derny, elimination, points and scratch races, the flying 200 m and the time trial, on 20 velodromes in 3D, against bots or other riders, on one computer or online. A handicap that learns each rider makes it a real race, even between a 120 W kid and a 340 W parent. You only pedal: the line up and down the banking is ridden for you. A race announcer and Coach Mac talk you through each race. It runs in Chrome and Edge, as an iPhone and iPad app in TestFlight, and as Android and Windows apps, and is free in open beta. I built it in 8 days with Claude Code.

Family platform

wilssens.com

Email and websites at the family domain for everyone named Wilssens: forwarding or a real mailbox at an address like [email protected], and a web address like https://steven.wilssens.com or https://leo.wilssens.com that points to an existing site or hosts a new one. Sites can be built in a visual page maker, uploaded, or published straight from AI apps, a command line and code editors, and approving a request sets everything up automatically, from the Zoho mailbox to the website address. Today it serves my immediate family for free; payments are built and switched off, ready if it ever grows beyond us.

Windows app

AI Breaker

The off switch for AI on Windows: a Windows 11 app that turns off the AI in Windows, Office and the browsers from one window, in four levels, shows what each level will stop before it is applied, proves afterwards from Windows’ own logs that it worked, and undoes everything in one click. Built for the half of adults who are more concerned than excited about AI, on the idea that people feel safer when they hold the switch. It uses only the controls Microsoft documents, never touches Defender, and is in testing now with a waitlist at $19 once.

Community project

Junior Track Cycling

An independent reference hub and training platform for junior track racers and the parents behind them: gearing and rollout rules kept as data, a rollout calculator, every discipline explained, ride analysis built for the velodrome, an AI coach with consent and safety gates for minors, and an MCP server so riders, parents and coaches can use their data from Claude. Built, and being ridden on the real track before it opens.

Family project

Leo Wilssens

A sponsor-facing media kit for Leo Wilssens, my son, a junior track sprinter: results, race reports, photos, velodrome rides and four browser games, with the rules for publishing about a minor written first and enforced in the build. Kept deliberately separate from the community hub.

This site

steven.wilssens.com

The site you are reading, built and run like a product. React pages are prerendered to static HTML and served from Cloudflare Pages, with every push to main deploying to production and every branch getting its own preview. Its own privacy-friendly analytics track visits, Core Web Vitals per device, and search engine and AI crawler traffic. Every page also comes as Markdown, with llms.txt and structured data, so AI assistants read it as well as people do. The resume PDF is generated from the same data as the pages, and a private MCP server lets me review the site the way a recruiter would and update it from a Claude conversation.
