We’re excited to announce Jannik Streek as a speaker at Agentic Conf Hamburg on March 22nd!

About Jannik

Jannik Streek is an Open Source Software Engineer at B310 Digital GmbH. He has been contributing to numerous open source projects for many years. Since mid-2025 he has been experimenting full-time with agentic programming, understanding what can already be achieved and identifying its remaining limitations.

The Talk: Beyond the Vibes: Lessons from Using Spec Driven Development Frameworks for Agentic Coding

Spec Driven Development (SDD) promises a better approach to agentic programming in larger software projects by focusing on the what, not the how: defining requirements from which implementation can be derived. Instead of going prompt by prompt and nudging code changes, specifications clearly separate requirements from implementation and let you think in capabilities.

Historically, specs were among the lesser loved artifacts in the software lifecycle — serving mainly collaboration, documentation, and compliance purposes. Now the tables might be turning, placing specs at the center of how we build software with AI agents.

In this talk, Jannik compares different Spec Driven Development frameworks (such as OpenSpec, SpecKit, and others), shares practical lessons from working on open source projects with them, discusses the challenges of adoption, and honestly explores when the overhead of writing specs actually pays off — and when it doesn’t.
