Senior🎓
Top SchoolErwin Graanstra is a pragmatic software engineer with a decade of experience building PHP-driven web applications, Magento extensions, and LAMP-based systems, currently running his own consultancy from Assen. He blends front- and back-end expertise (Yii2, Spring MVC, JS, HTML/CSS) with hands-on Linux administration and security, and occasionally dives into C#, Java, Python and Lua for niche tasks. His background includes e-commerce and gaming sites where performance and maintainability mattered, and he’s comfortable shipping both plugins and small open-source tooling. Outside code he does audio mastering—a detail that reflects a meticulous ear for quality and refinement. Known for a direct communication style, he encourages persistence from collaborators: retry or quit.
