Rockstar🎓
Top SchoolJoey De L'arago is a software engineer based in Brussels with nine years of experience building desktop and backend systems across Python, C++, Java/Typescript and cloud services. He has worked on Cura, the leading open-source 3D printing slicer, contributing bug fixes and geometric algorithm improvements in the slicing engine and improving G-code generation for better print accuracy. Joey has experience spanning full-stack desktop app development (PyQt/Python), microservices and high-throughput report generation, plus automation via GitHub Actions. At Ultimaker he combined technical contributions with community management, running meetings and reviewing community PRs, and at Over-C he helped migrate a monolith to microservices while integrating AWS services and resilient queues. Now working at Enprove and Materialise, he brings practical production experience in both low-level C++ optimizations and higher-level system design. A detail-oriented engineer, he often surfaces subtle algorithmic and calculation fixes that materially improve real-world hardware outcomes.
