About Me
Michael Wellner
- Fullstack Developer -
As a Fullstack Developer based in Stuttgart, Germany, and now in my late 30s, my expertise lies in creating robust Java / Spring Boot backends, managing data via MySQL/Postgres and intuitive Angular frontends. I bring over a decade of experience focused on clean code, domain-driven design, and agile methodologies that lead to maintainable, scalable solutions. Additionally, I thrive in collaborative environments, utilizing standard industry tools like Git, IntelliJ, Jenkins, etc.
Throughout my career, I've specialized in developing microservice architectures that handle complex business requirements. I enjoy solving challenging technical problems - but always with the goal of delivering real, long-term value.
I believe in continuous learning, sharing knowledge, and mentoring the next generation of developers.
In the complex world of code, simplicity is the ultimate sophistication.

Tired of Auth Overkill? Meet idently - Simple, Stateless Deno Identity Gets Smarter
At its heart, idently is my take on dead-simple, stateless authentication built with Deno. The core idea? Forget emails and passwords. Just give users a secret code. They send the code, they get a JSON Web Token (JWT) back.
MaverickWave - I finally published my own CSS framework
After countless false starts over the years, I'm excited to finally share MaverickWave with you - a lightweight, responsive CSS framework I've built for modern web development. This project represents not just code, but a personal milestone in my journey as a developer.
