About me

An experienced practitioner in architecture and modernisation

I am Jan Marco Schreier, a freelance IT architect and transformation consultant with over 20 years of experience in software development, software architecture, DevOps and technical consulting.

My focus is modernising business-critical software systems that have grown over many years. I combine architecture work, automation and hands-on technical implementation with technical coaching. What comes out of it is not just concepts but solid technical foundations – and teams that can carry the solutions forward themselves.

I have worked as a Cloud and Software Architect, Principal IT Consultant, Lead DevOps Engineer, Technical Coach and Product Owner, among other roles. These different perspectives help me bring technical, organisational and business requirements together and develop practical solutions.

In my daily work I use AI-assisted and agentic tools productively – for analysis, implementation, refactoring, documentation and quality assurance. The review, both on the substance and on the technical side, expressly stays with me: I work human-in-the-loop, check results against the architecture and automate quality assurance rather than trusting the tools blindly. I have built and proven this way of working in an application of my own – including connecting existing systems through custom MCP servers.
