Briefe über das Bauen, Identität, Verantwortung und die Arbeit, die nicht in Git sichtbar wird. Persönlich und technisch. Kein Zeitplan, kein Funnel. Ein Brief erscheint, wenn es etwas gibt, das es wert ist, gesagt zu werden.
Certificate renewal had been failing for thirteen days. The blackbox exporter said 75 days remaining. The origin had 17. When a CDN terminates TLS, every external certificate probe you have is measuring the wrong certificate.
Brief lesenMulti-tenant isolation with a Postgres schema per bounded context. Separate Flyway migration streams, a separate EntityManagerFactory each, and the HikariCP pool sizing that quietly decides whether your decomposition survives contact with max_connections.
Brief lesenSwapping the message broker under a 65-module Kotlin modular monolith. Six versioned topics, KRaft, an idempotent producer with acks=all, and why every publish call site stayed exactly as it was.
Brief lesenDanceClub now speaks 15 languages. The gap between two and fifteen closed in one night. The hardest bug wasn't the translation. It was the safety net.
Brief lesenA spreadsheet with 72 dance events across Europe. Instead of weeks of data entry, I built a pipeline that scrapes, validates, and publishes. 59 went live. 13 were correctly refused.
Brief lesenA Facebook share URL that returned nothing. An event website that redirected to a different business. An Instagram profile instead of an event page. When you automate at scale, 'event link' means 10 different things.
Brief lesenA real PulseAI crisis: a production workflow that compiled, passed every validator, and silently shipped wrong data for three days. What the fix proved about Rule III and Rule VIII of the manifesto.
Brief lesenSix months to build DanceClub. More than two years to become the person who could. A letter about responsibility, the work that doesn't show up in git, and the laptop my mother bought me with the last money she had.
Brief lesenKein Zeitplan, kein Spam. Eine E-Mail, wenn ich etwas Neues veröffentliche. Jederzeit abbestellbar.
