Summary
🤩
Rockstar🎓
Top SchoolSteven Looman is a seasoned Smallworld DevOps consultant and GIS-focused software engineer with 15+ years of experience building and automating large-scale Smallworld environments for utilities and infrastructure clients. He blends hands-on Magik and Python development with DevEx improvements—creating language servers, linters, and code-coverage tools used by other companies to speed and harden Smallworld development. Steven has led migrations to cloud and Git-based workflows, automated CI/CD for mixed Windows/Linux landscapes, and integrated Smallworld with APIs, Kubernetes, and monitoring stacks like Datadog and Splunk. He also contributes to open-source Python projects such as Home Assistant, where he improved UPnP device discovery, showing a pragmatic interest in broader developer ecosystems. Based in the Netherlands, he pairs an MSc in Computer Science with strong communication and project leadership skills that bridge domain experts and engineers. Not obvious at first glance: he actively builds tooling that applies typing-style checks to Magik, catching bugs before runtime and materially improving developer productivity.
