Rockstar🎓
Top SchoolAndreas Kohn is a Principal Engineer with 14 years of experience building and evolving scalable products, currently shaping architecture and delivery at Framer after a long tenure as Chief Architect at NEXT. He combines a pragmatic eye for big-picture system design with a knack for reading and fixing legacy code—something he genuinely enjoys—spanning front-end React toolkits like remirror and back-end systems around Kafka, Kubernetes, and C/C++ libraries. A long-standing Apache committer (Shiro, formerly Shindig), he routinely contributes careful bug fixes and clarity improvements that increase robustness and maintainability in widely used open-source projects. His background in migrating monoliths to microservices and moving data platforms from MongoDB/Elasticsearch to Kafka underlines his strength in operationalizing complex data flows. Based in Amsterdam, he brings both product-focused thinking and deep engineering craftsmanship to teams building user-centric, evidence-driven products.
