I am a senior enterprise architect. I design and build distributed systems and other complex systems, and I work on AI engineering and inference engineering: taking language models from a prototype to a service that runs reliably and at a sensible cost in production. I founded systemdesign.academy, where I teach system design and AI engineering in plain English. I teach the same topics on my YouTube channel, Total Technology Zonne. Here you can book a 1:1 mock interview with written feedback, a resume and LinkedIn review, or an architecture consultation for your team. You can also buy my interview prep packs (AI Engineering, GenAI and LLM Engineering, Inference Engineering, Maths for ML, Forward Deployed Engineer). Each one is a PDF with real interview questions, full answers and a diagram for every question.
