Juni 2026 bin ich zu Gast bei der Java User Group Hamburg und zeige, wie Spec-Driven Development mit dem AI Unified Process (AIUP) in echten Java-Projekten funktioniert. 🎟️ Anmeldung: https://www.meetup.com/de-de/jug-hamburg/events/314804008/17 May 2026 07:55 +0000at://did:plc:detb4ybuqm4rx75degde6pcq/app.bsky.feed.post/3mlzv3q5pmb23https://bsky.app/profile/martinelli.ch/post/3mlxemshjlk2qNew tutorial online: Build a web app with the AI Unified Process unifiedprocess.ai I published a new step-by-step tutorial for the AI Unified Process: Build a web app from a blank canvas to a tested application.

Code is generated from it. Tests are derived from it. Decisions are based on it.

The test proves the contract holds.

Estimated effort without AI: several days. AI didn't just help with the coding. It helped with the conception, too. #AI #SoftwareDevelopment #Productivity11 Apr 2026 08:20 +0000at://did:plc:detb4ybuqm4rx75degde6pcq/app.bsky.feed.post/3mj7fpp63mk27https://bsky.app/profile/martinelli.ch/post/3mj5umhmzgk2zluma.com/busybk3l https://luma.com/busybk3l10 Apr 2026 17:41 +0000at://did:plc:detb4ybuqm4rx75degde6pcq/app.bsky.feed.post/3mj5umhmzgk2zhttps://bsky.app/profile/martinelli.ch/post/3mgtwdw467c27Spec-Driven Development is not for developers alone. It is the bridge between business and development. Without business, there are no requirements. Without requirements, there are no specifications. And without specifications, teams may still build software, but not necessarily the right thing.12 Mar 2026 07:55 +0000at://did:plc:detb4ybuqm4rx75degde6pcq/app.bsky.feed.post/3mgtwdw467c27
