Luka Breitig a créé Tymeslot et en assure la maintenance. Il a conçu le moteur de planification, la couche de synchronisation CalDAV, l’interface de réservation en Phoenix LiveView et l’infrastructure du widget intégrable : les systèmes documentés dans ces pages. Il travaille comme ingénieur logiciel et développeur IA.
Son expertise technique couvre deux domaines :
Parmi ses autres projets en ligne figurent In A Nutshell (recherche sémantique par IA dans les contenus vidéo, avec citations horodatées) et Transvexis (traduction multilingue au service de clients dans plus de 39 langues).
En parallèle, Luka forme des équipes d’ingénierie au développement logiciel assisté par l’IA : workflows agentiques, revue de code par l’IA et prise en main de bases de code inconnues avec des outils comme Claude Code et Cursor. Il anime des ateliers pour des organismes tels que NobleProg et Cegos Integrata, et est intervenu lors de conférences internationales de développeurs sur l’intégration de l’IA et les bonnes pratiques en production.

A booking page looks like a form over a calendar. The hard part is that every calendar system disagrees about which events make you busy, and once my code answered that question in two places, the two answers disagreed too.

I put out the first version of Tymeslot two days ago. I built it because the scheduling tools I tried were either dated or too heavy to run myself.
