Martin Hölzemann

I’m an IT leader and software development team lead with more than 20 years of experience building and scaling digital solutions. My journey started back in the 90s as a print and web designer, then moved into web development in the early 2000s, and later into leadership roles where I’ve been shaping teams and technology strategies ever since.

Most recently, I led international developer teams at CHECK24, one of Germany’s biggest e-commerce companies, driving scalable architectures, APIs, and agile workflows. Before that, I served as Head of IT in a mid-sized retail group, responsible for IT strategy, infrastructure, and custom development.

Alongside my professional career, I explore how to bring AI and app development together. Some of my projects include the Zenvale App (Sleep & Relax Sounds) and ongoing work on the Zone System Trainer and a Scheimpflug App for large format photography.

🔧 Skill set highlights:

  • IT leadership, agile team management, mentoring
  • Software architecture & digital transformation strategy
  • AI integration in mobile apps (Flutter/Dart)
  • Backend development (Symfony, APIs, MySQL)
  • Project management with Scrum, Jira & Confluence
  • EDI (openTrans) and B2B applications


What drives me: combining technology and business, helping teams grow, and turning innovative ideas into sustainable digital products.
