About Djim

I’m Djim Molenkamp, a software engineer based in Amsterdam.

I studied Aerospace Engineering at TU Delft and specialised in Control & Simulation. My thesis was on reinforcement-learning-based controller selection, and the research on controller selection for aggressive quadrotor manoeuvres was published by the AIAA in 2017. Along the way I ran MediaCopters, a small aerial filming company, and worked as an early engineer at Avy, an Amsterdam/Berlin drone startup that was accepted into the European Space Agency’s incubator programme.

At the end of 2016 I moved into software, and I’ve worked as a freelancer for most of the time since: BinckBank, GLS, KLM (twice: first at the Digital Studio on computer vision and a digital twin of Schiphol, then at BlueLabs connecting the Engine Shop’s machines), Remia, Kadaster, and since 2023 Tata Steel, where I’m lead developer on a platform for the Secondary Steelmaking process. I like the work where software meets physical systems, because there a bug costs more than a page reload.

Long before all that, in 2002, I started DjimDesign, a small web design company building custom websites for clients. In 2024 I turned it into something new: an AI-first studio where a team of AI agents designs, builds, tests and writes, and I act as CEO and final reviewer. It’s the most interesting engineering problem I’ve worked on, and I write about how it goes in Notes.

I’m Dutch, and I speak six languages, some better than others.
