Profile
I?m a highly experienced and technically adept Full-stack Developer (albeit more specialized in Frontend frameworks like React and React-Native), who can writeclean, maintainable, and optimized code in multiple programming languages like TypeScript, Java, C#, Ruby, PHP and HTML5. By virtue of an excellent understanding of complex data models and algorithms and the ability to get acquainted with and make use of cutting-edge developments and frameworks, I can be a very productive and helpful addition to any development team. I?m also able to manage and guide groups of fellow colleagues, as proven at several client projects where I have overseen small development teams or at my employment at the University of Bonn as a tutor / mentor in courses like Software Technology and Object-Oriented-Programming.
