00. About Me
I'm a freelance software developer from Germany. I have over 20 years of experience in the industry. My strength is taking projects from idea to reality and overseeing the whole process. I enjoy working closely with the product team to find the best solution for the customer. I have a track record of working with cross-functional teams, leading and mentoring junior developers and delivering results on time and within budget.
When I'm not coding you'll find me on my bike or in the workshop doing woodworking.

LYNQTECH Cloud-Plattform for Energy Providers 2023 - now
https://lynq.techAs a front-end architect, I am responsible for overseeing the complete software development lifecycle. This encompasses tasks such as design, development, testing, deployment, and maintenance. I actively engage in understanding user requirements, crafting system architectures, coding, cooperate with cross-functional teams, and placing emphasis on scalability, quality and performance. By giving deep dive TypeScript trainings I helped the team to grow and increase the general code quality in the project. Through my code reviews, I support my colleagues in the practical application of the topics they have learned and help them to further deepen their knowledge.
