About Me

A fullstack developer with a passion for software architecture, security, and an eye for frontend design.

Personal

As a Fullstack Developer at Alfred Kärcher SE & Co. KG, I develop scalable web applications for e-commerce and IoT platforms on a daily basis. My passion lies in crafting thoughtful software architectures specifically designed for the AWS cloud – with a strong focus on performance, scalability, and security standards. Using technologies such as Next.js, TypeScript, GraphQL, and soon .NET, I bring ideas to life. It's important to me that teams can collaborate efficiently – that's why I establish standards, share knowledge, and ensure security is considered from the start. What drives me: Limited time, but infinite possibilities to make a difference.
