It all started with

... a great Christmas present 28 years ago: my first own computer. The performance of this 'marvel of technology' is currently probably surpassed by any better smartwatch, yet this PC was the cornerstone for my way into the digital world of today. With it I learned the basics of a text-based operating system, how to use a mouse and what this Minesweeper was all about.

Since then I am interested in everything that has to do with bits and bytes. The area doesn't matter, from A like Artificial Intelligence over M like Mobile Device Development up to Z like the ZIP-Algorythm.

My professional qualifications

Dream job: software engineer? For me it really is! Today, 20 years after the beginning of the training, I not only have a profound expertise in almost all areas of agile software development, but also in parts of DevSecOps as well as first experiences as a teamlead due to my long-term professional activity.

This know-how has been gained through the implementation and support of a large number of projects as well as my personal interest in realizing them with the help of the latest technologies.

What distinguishes me

An always concentrated and conscientious way of working and the ambition to continuously deliver optimal work results. I value solid communication as well as close cooperation within the team. In addition, my colleagues can rely on me at all times. What's more, I'm motivated, like to familiarize myself quickly with new projects and fields of activity, and am eager to develop professionally.

About me personally

I was born 36 years ago in Augsburg, Germany. I successfully completed my traning as an IT specialist in the field of application development 17 years ago and have been working as a software developer in the field of web technologies ever since.

Besides my professional hobby I also like to spend my free time on the motorcycle or behind the camera. In the latter, I am particularly fond of macro and wildlife photography.

Teamwork

For me, teamwork is the fundamental element of excellent software development, based on mutual trust and respect.

I actively establish a culture of open knowledge exchange and collaborative problem solving through methods such as pair programming.

This approach not only strengthens team spirit, but also leads to high-quality solutions more efficiently through diverse perspectives.

Leadership

For me, modern leadership means creating an inspiring environment in which innovation and individual excellence flourish.

I lead teams with a clear vision and empathy, fostering the personal development of each individual through constructive feedback and coaching.

My focus is on building psychological safety to form high-performance teams that deliver outstanding results on their own responsibility.

Mentoring

I consider targeted mentoring to be an essential investment in the sustainable development of the team and long-term knowledge transfer.

I actively accompany colleagues through code reviews and workshops to deepen technical understanding and firmly anchor best practices.

It is my personal aspiration to empower others to surpass themselves and take responsibility for their own career path.

Communication

Precise and target-group-oriented communication forms the backbone of successful projects and sustainable stakeholder relationships for me.

Through my experience in technical project management, I convey even complex issues in an understandable way between development and management.

I attach great importance to a transparent, solution-oriented dialogue in order to proactively avoid misunderstandings and clearly define shared visions.

Quality standards

My quality standard defines software that is not only functional, but also robust, scalable, and maintainable in the long term.

By using modern technologies and best practices such as Clean Code, I ensure sustainable architectures from the very beginning.

A comprehensive test strategy with automated procedures ensures this high standard and creates confidence in every release.

Planful working

A structured and methodical approach is for me the indispensable basis for the timely realization of complex projects.

Through detailed analyses and realistic milestone planning, I always maintain control over resources and schedules even in critical project phases.

Proactive risk management and transparent communication ensure predictable and smooth project success.
