Refined digital experiences,engineered with intent.
Rotterdam-based full-stack engineer. I help teams ship web products, sharp interfaces, AI integrations, and reliable delivery pipelines, with whatever stack the product needs.
Hello
I'm Max Kruijs Voorberge, a Senior Full-Stack Engineer from Rotterdam. I work across modern product and platform implementation, not one fixed framework. That can mean interfaces, APIs, auth, databases, integrations, deployment and the architecture between them. I like turning messy product requirements into software that feels clear, fast and maintainable. For client work, reach me through MKV Labs, the company behind my software, AI and product work.
Work that's considered, built to last.
I build products end-to-end: interfaces, APIs, AI, performance, and the pipelines between them.
Web & Full-Stack Development
Production apps, dashboards, webshops and content platforms with clean architecture and the stack that fits the product.
AI & LLM Integration
Local or cloud LLM features with retrieval, streaming responses, agent loops and connections to real workflow data.
Code Quality & Maintainability
Type-safe foundations, API contracts, tests and standards that make a codebase easier to extend.
Performance & Web Vitals
Lighthouse and Core Web Vitals work across bundles, assets, metadata and the details that keep pages fast.
CI/CD & DevOps
Automated test, preview and release pipelines with GitHub Actions, GitLab CI, Azure DevOps, Vercel and Azure.
