Luka Breitig criou o Tymeslot e cuida da sua manutenção. Ele construiu o motor de agendamento, a camada de sincronização CalDAV, a interface de agendamento em Phoenix LiveView e a infraestrutura do widget incorporável: os sistemas documentados nestas páginas. Ele trabalha como engenheiro de software e desenvolvedor de IA.
Seu foco técnico abrange duas áreas:
Entre seus outros projetos em atividade estão o In A Nutshell (busca semântica com IA em conteúdo de vídeo, com citações por marcação de tempo) e o Transvexis (tradução multilíngue que atende clientes em mais de 39 idiomas).
Além de desenvolver, Luka capacita equipes de engenharia em desenvolvimento de software assistido por IA: fluxos de trabalho agênticos, revisão de código com IA e navegação em bases de código desconhecidas com ferramentas como Claude Code e Cursor. Ele ministra workshops para organizações como NobleProg e Cegos Integrata e já palestrou em conferências internacionais de desenvolvedores sobre integração de IA e padrões para produção.

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.
