01 · positioning

I am a senior web engineer, specialised in headless platforms and Next.js. Over eight years, including a year and a half as front-end tech lead on a headless e-commerce platform, I have worked from rendering all the way to production. I also cover the back end and the infrastructure, as an extension of the web.
