CTO at Laudus (Visma group), with ten years building and running web platforms. I'm obsessed with automation: containers that make processes run themselves, for the development team and for customers alike. Day to day: Python, Django, PostgreSQL, Docker, AWS and CI/CD. Outside work I experiment with containers, CI/CD and AI agents at jaimesa.nz.
