Senior🎓
Top SchoolCarl Colijn is a senior software engineer with over eight years of professional experience and a long history of hands-on development dating back to the late 1990s, currently building video transition frameworks and build-tooling for Adobe Premiere Pro. He is a versatile full-stack developer and owner of a small software firm, comfortable shipping native Windows/Mac applications, Office/Access solutions, web tooling and Python scripts, often combining low-level APIs, GPU compute kernels and IPC in cross-platform C++ projects. His tooling fluency spans Visual Studio/Xcode, gcc, VBA, VBScript and both Git and SVN, and he’s improved release automation for popular open-source work such as the ShadowFox Firefox theme. Equally at ease in agile teams or classical setups, Carl focuses on code quality, build chain enhancement and pragmatic integrations like analytics and licensing. Based in Arnhem, Netherlands, he pairs an MSc background in molecular sciences with a pragmatic engineering mindset shaped by decades of diverse client and product work.
