Summary
🤩
RockstarJon Ronnenberg is a pragmatic full-stack and mobile developer with 16 years of experience building thin, decoupled web and mobile architectures across browser, server and native platforms. Based in Copenhagen, he has deep JavaScript expertise (Node.js, functional and OOP patterns), Titanium mobile development for iOS/Android, and a long history of frontend work using AJAX, CSS3 and HTML5. He pairs hands-on engineering with strong test and CI instincts—contributing to well-known open-source projects like svg.js, laravel-mix and tapjs with improvements to testing, cross-platform reliability and build tooling. Jon’s approach favors thin clients, generic data access layers and future-proof separation of concerns, enabling independent evolution of each layer. He is multilingual (Danish/English, reads Swedish, understands Norwegian) and combines a curious, pragmatic mindset with a track record of maintaining code quality and robust test suites.
