Top SchoolThomas Kellermeier is a Senior Software Engineer based in Berlin with 11 years of experience building and leading full-stack web teams, currently at Contentful.

As former lead at neXenio he drove a collaborative web app from concept to production using Kubernetes, Docker, Node.js, React, Redux and GraphQL while supervising sprints and customer feedback. His academic background from Hasso Plattner Institute and early work at TomTom and in research projects gave him a strong algorithmic and ML grounding, applied to real-world problems like city-scale parking search optimization. Outside of work he experiments with applying machine learning to practical apps and explores adjacent fields such as electrical engineering, reflecting a persistent curiosity beyond typical engineering duties.
