    As part of my computer science studies and numerous personal software projects, I develop modern web, mobile, and backend applications. I work independently from planning through UI/UX design to implementation and deployment.

    My focus includes Android development (Kotlin, Jetpack Compose), web development with React and TypeScript, Firebase (Authentication, Firestore, Hosting), REST APIs, and the development of custom client solutions.

    In addition to my studies, I have implemented various projects for clients and my own applications. These include event platforms, management software, mobile apps, web apps, as well as cloud and hosting solutions. I place particular emphasis on clean code, performance, security, and a good user experience.

    I quickly familiarize myself with new technologies and accompany projects from the initial idea to the finished product.
