Summary
👤
Senior🎓
Top SchoolJonas Lith is an experienced systemutvecklare based in Stockholm with 13 years of professional software development, currently building payment services at Svea Ekonomi using Java EE and C#. He is pragmatic about code quality, specializing in test-driven development, refactoring, and design patterns to deliver maintainable systems. His broad language and platform fluency—C/C++, C#, Java EE, Python, PHP, JavaScript, .NET, Linux, OpenGL and SQL—lets him move between backend services, embedded work and tooling with ease. Jonas pairs an academic foundation in engineering physics and computer science with hands-on embedded experience from early internships, which informs a practical approach to concurrency and systems-level thinking. He’s comfortable both writing unit and functional tests and shaping architecture, often favoring incremental design improvements over big rewrites. Colleagues would note his steady delivery on financial systems and a mindset that balances robustness with pragmatic shipping.
