My name is Tim Sommer. I'm an Enterprise Architect at a Belgian insurance broker, based in Antwerp. I've been passionate about computers and programming for as long as I can remember. I watched the .NET Framework rise as a student, spent the better part of my career building on Microsoft technologies, and somewhere along the way shifted from writing code to making the architectural decisions that determine how systems evolve.
These days my focus is on Enterprise Architecture, AI governance, data platforms, and the practical engineering decisions that sit between a whiteboard and a production system.
I write here about what I find. Architecture decisions, AI systems, honest assessments of tools that are overhyped and tools that quietly work. My audience is practitioners; other architects, senior developers, tech leads who'd rather read one honest post than ten optimistic ones.
Beyond the technical: I'm a speaker and occasional educator. I care about volunteering, the environment, social equality, and the open web. I like music, travel, and long runs & hikes. I'm an amateur photographer. I practice Zazen. I read a lot. I never seem to have enough time, which is probably why I built a pipeline to write code for me.
Posts on this blog are written by me, occasionally drafted with AI assistance.
The ideas, opinions, and hard-won lessons are always my own.
