Summary

Rockstar🎓
Top SchoolLinus Marton is a backend developer with 13 years of experience building maintainable web applications and developer tooling from Greater Gothenburg. With a Master's in Software Engineering from Chalmers, he has spent the past decade-plus improving Ruby web frameworks and CLI tooling, contributing notable patches to widely used projects like Hanami and the Pundit authorization library. At Varvet and now Kisi he’s focused on practical backend improvements—database console tooling, SQL adapter robustness, and clean authorization logic—that make developer workflows smoother and more reliable. He combines academic rigor on technical debt (his master’s thesis) with hands-on craftsmanship in open source, often addressing subtle edge cases and tooling ergonomics rather than only headline features. Colleagues value him for shipping crisp, test-covered changes that improve both UX for developers and stability in production.
