This is my November Fedi reminder that I am a talented #Java developer looking for a developer position either remote, or based in Tampa, FL. I have some neat skills, like #CoreJava, #JavaEE, #Spring Frameworks, #WebServices, #Kafka, and many others. If you want to set up a call, I promise I will respond. (And I only ask you apply the same rule.)
Oh yeah, something-something-pumpkin-spice; now it's a November post.

Wer glaubt, URL-Verkürzung sei nur UX, irrt. Entropie entscheidet über Vertrauen, Kollisionen über Haftung. Ein Shortener ohne Architektur öffnet Tür & Tor für Missbrauch. #Java24 liefert die Werkzeuge. @svenruppert zeigt wie.
