Available to hire
Hi, I’m Eze, a full-stack JavaScript/Node.js engineer with 15+ years of experience building web apps and services that scale. I work mostly with Node.js, React, and TypeScript, and I’m certified by the Linux Foundation (Node.js) and AWS (Developer Associate).
At Adevinta, I’m part of the platform team behind Marktplaats. I focus on BFF architecture, micro-frontends, shared libraries, and tooling. This includes internal SDKs (React and Node.js servers), design systems, reviewing tech radars, assessing technologies, maintaining a custom SSR engine, and working with Next.js. I also contribute to CI/CD automation to streamline development workflows and take part in an internal AI guild, where I explore and test tools to boost engineering productivity.
