Hi, I'm Jens

I'm a cross-platform mobile engineer and Tech Lead at November Five. Day to day that means leading a team of four to six engineers and a QA, staying close to the codebase, and thinking about how we build things well — across iOS, Android, and Kotlin Multiplatform.

I've been in mobile since 2014, starting as an iOS engineer and gradually expanding from there. React Native, some frontend web, then Kotlin Multiplatform. Android isn't my native ground, but I can navigate the codebase when needed. Before that, I did a Master's in Electronics-ICT with a focus on ICT, graduating in 2013. My thesis was on machine learning — building a model to recognise sounds in a home environment. An early interest in AI, back when it was purely ML.

AI has become part of how I work: how I plan, how I write code, how I lead a team. I've been experimenting with that seriously since fall 2025, and this is where I write about it — not as finished thinking, but as a working log from someone doing it in a real context.

Outside of work: I spend time with my fiancée and our cat. I cycle, I lift, and occasionally show up to a CrossFit class. I also do photography — mostly landscapes, the kind that require a hike to get to.

That's the short version. The rest is in the posts.
