Over deze dienst

Your website already works. It just loads too slowly, loses search visibility, or has accumulated frontend debt.


I audit and improve real React and Nextjs codebases. This is not a template website service.


I focus on the issues that affect production products:

Core Web Vitals and Lighthouse bottlenecks

JavaScript, images, fonts and third-party scripts

React and Nextjs rendering boundaries

Technical SEO, crawlable routes and metadata

Monitoring, analytics and safe production changes


You get a clear before-and-after summary, implemented fixes within scope, and a practical backlog for the rest.


I build production e-commerce experiences at MANGO, including global store search for around 3,000 locations, loyalty, navigation, performance and technical SEO.


Message me before ordering if your work spans multiple apps, a monorepo, or needs a larger refactor.

I’m a full stack developer specializing in Next.js, Typescript, and AWS. Currently, I freelance at Mango, where I improve and optimize user interfaces to enhance the e-commerce experience. I also co-founded Catalyst Creativity, an AI-driven tool designed to streamline creative processes. My strength lies in solving complex technical problems and transforming ideas into functional, scalable digital products: sleek frontends, powerful backends, and full SaaS solutions.
