Together with two other business partners, I bought a well-functioning social media agency with which we take care of the marketing and placement of Creator on Instagram and TikTok. This allows us to realize advertising campaigns by connecting the right brands with the creators on the platforms.

I am now a self-employed entrepreneur in the B2B sector and implement complex web applications of all kinds according to the wishes of my customers. I also operate my own servers, which give me the opportunity to offer my customers managed hosting and individual server solutions.

Civilian service in training and further education. During this activity, I assisted in the supervision of organized training courses, carried out office work and performed general support work.

The first internship in August 2018 became a part-time position from February 2019 until mid-2023 with repeated short-term hourly increases as an intern during the summer vacations. Here, activities such as design & implementation of web layouts and frontend applications, development and implementation of responsive designs, testing & quality assurance of the applications created, development and conception of user-friendly websites, implementation of digital advertising media, programming support for the lead backend developer, independent planning and implementation of large parts of a PHP-based ERP system of a travel provider and implementation of a visualization dashboard of a mailing product were carried out. We worked with PHP, JavaScript, jQuery, AJAX, CSS, CodeIgniter, Symfony, Bootstrap, Tailwind and MySQL.

In this internship, I found a place in the MRUM team (Mobile Realtime User Monitoring), where I had the opportunity to get to know React, Kubernetes, PostgreSQL, unit testing with Jest and NX.

This was a week as an initiative of my high school to get to know a profession of his choice better. This gave me my first contact with the profession of software developer.
