AI product designer and developer — AI products, learning systems, interactive web experiences. Hannover, Germany · working in English and French.
Background in learning design (Chief Learning Officer at MCR until 2022), French law, court mediation and negotiation — which is why the products I build handle rules, incentives and trust.
I design the product and make the technical calls — architecture, stack, interactions — then direct AI coding tools that build to my spec. I review and test everything that ships. The work below runs on the page: lorenzocolombani.com.
| Work | What it is | Live |
|---|---|---|
| OpenBots (v0.5.0) | Claude as a team of persistent, named teammates — a native macOS app with durable local state, explicit approvals and six built-in characters. No API key; it rides the subscription. Swift 6, MIT. Preview build: the executor for consequential actions is disabled. | Repo |
| Data Vault Foundations | A 14-chapter interactive learning platform on Data Vault 2.1 — architecture, SQL, dbt, EU compliance, Python — with quests, feedback and hands-on exercises. | Open |
| TVA Case File | A motion-and-typography case file in the language of the Loki title sequence: seven "deviations," one timeline, running in the browser. | Open |
| "AI, Applied." | 87 real-world AI use cases from 15 contributors, 94+ tools — convened the contributors and built the site for the Wharton Alumni AI Studio (an alumni nonprofit). Astro, React, GSAP. | Open |
| The Bridge | An interactive web film — Three.js portals, GLSL, GSAP. A 4.5-minute proof that a method can be a place you walk through. Score: Kevin MacLeod. | Open |
