What I'm looking for

I seek backend-focused roles leveraging Go and cloud infrastructure, with opportunities to influence architecture, improve performance, and work in collaborative Agile teams; preferably in companies valuing technical ownership and clear impact.

I am a senior software engineer with roughly 10 years of professional experience, dual Dutch/English nationality, and full professional fluency in English and Dutch. I began my career in PHP/LAMP backend development, moved into game development with C++ and Java, and for the past few years I have focused primarily on Go for server-side solutions, delivering production systems, CMS platforms, streaming applications, and real-time telemetry tooling.

I have experience across the full backend stack — databases (MySQL, PostgreSQL, MongoDB), server frameworks (Symfony, Laravel), cloud and ops tooling (AWS, Linux, Nginx) — and have contributed to architecture, user stories, automated testing frameworks, and performance optimization. Notable achievements include shipping a custom real-time web app for sim-racing telemetry and diagnosing/fixing a long-standing force-feedback bug by implementing custom DInput logic.
