Michiel de Gooijer
AI Tutor | Senior Developer | Web Apps, iOS & Android | From Idea to Launch
PROFESSIONAL SUMMARY
10 years of experience in software development, starting with Microsoft Dynamics 365 Business Central (AL programming, custom extensions, API development, ERP automation) and now fully operating at the intersection of AI and modern web development.
I use AI-powered workflows and "vibe coding" with tools like Claude Code, Codex, Z.AI, MiniMax, and the latest Kimi models to go from idea to production in days, not months. I don't just follow AI trends — I build with them daily, picking whichever model or tool gets the job done fastest.
Currently building cross-platform iOS and Android apps and shipping multiple SaaS products as a solo developer and digital nomad. Extremely strong at connecting APIs — whether it's stitching together AI services, payment providers, mapping tools, or third-party platforms, I make systems talk to each other fast and reliably.
I am highly adaptable and open to all working arrangements, including remote, hybrid, on-site, and relocation for the right opportunity. My focus is on delivering value and driving impact, from idea to launch.
