System Designing Software Developer

👨‍💻 I’m Jonas, a Software Developer with a keen focus on crafting robust Software Architectures in ☕️ Java. I thrive at the crossroads of business and technology, always keeping a pragmatic perspective on both realms.

👉 My approach is rooted in a combination of proven methodologies, including Extreme Programming (XP), Test-Driven Development (TDD), and Domain-Driven Design (DDD). I believe that these principles pave the way for scalable, efficient, and maintainable software solutions.
