Gothenburg, Sweden
Summary
👤
Senior🎓
Top SchoolDennis Axelsson is a CTO and founder with a decade of hands-on software experience building full-stack systems from scratch, primarily in TypeScript and Java. He specializes in TDD and Clean Code, architecting scalable web and mobile platforms—designing databases, server backends, web-admins and apps for startups and enterprise clients. His work spans React, GraphQL, REST, and CI/CD on Kubernetes/AWS, with a track record of migrating monoliths to modern microservice and BFF architectures. Equally comfortable leading teams and writing production code, he mixes pragmatic engineering with an early-adopter mindset for frameworks and emerging AI trends. Based in Gothenburg, he brings entrepreneurial grit from founding Knegus AB and hands-on CTO leadership at Piffl, and off-hours he channels teamwork and discipline into football, futsal and piano.
