04 / About MWAR
The specialist behind MWAR
MWAR is my IT services business, combining software development, cloud and infrastructure expertise with practical delivery. I’m Martijn Warrink. With more than twenty years of experience in software and IT, I help organisations turn ideas into working, maintainable solutions.
I approach complex challenges from multiple angles. I can develop the application, automate its deployment, set up the infrastructure and work with users and teams to understand what is needed. No unnecessary layers or complicated handovers: you work directly with the person delivering the work.
Alongside my professional work, I continue to explore new technologies, including Rust and modern infrastructure. I’m analytical, practical and take responsibility for the outcome.
