Vincent Grimmeisen

Software & Security Tester | Expert in Secure, Scalable, and AI-Driven Software Development
Vincent Grimmeisen is an experienced software and security tester with a strong focus on developing secure, scalable, and innovative software solutions. He has a particular interest in the integration of artificial intelligence into modern software development processes to elevate efficiency, quality, and security to a new level.

He holds a Bachelor of Science in Computer Science and has over five years of hands-on experience in IT security and software development. This combination of academic background and practical expertise gives him a comprehensive perspective on the technical, organizational, and security-related aspects of modern IT systems. One of his most formative experiences was his involvement in a Software-as-a-Service (SaaS) project, which he supported successfully from initial concept and minimum viable product (MVP) through to international release. At the same time, he advised clients on IT security issues and conducted security audits.

As a trainer, Vincent provides practical instruction on the possibilities and limitations of modern AI-supported programming tools. In his courses, he emphasizes a deep understanding of the underlying technologies as well as a responsible and efficient use of these tools. Topics include the core features and working principles of GitHub Copilot, Claude Code, and Gemini CLI, supplemented by methodological foundations such as "lossless feedback loops"—a concept for continuously optimizing development processes through targeted feedback and learning cycles.

His technical expertise is backed by recognized certifications, including:

Offensive Security Certified Professional (OSCP)
Certified Red Team Operator (CRTO)
Certified Information Systems Security Professional (CISSP)
