About me

I am a com­puter science stu­dent based in Ber­lin. I star­ted to deve­lop a pas­sion for pro­gram­ming and web de­ve­lop­ment in 2015. Du­ring that time I did an appren­tice­ship as an IT systems engineer, which I suc­cess­fully fi­nished half a year ear­lier than expec­ted in Fe­bru­ary 2016. Du­ring that time I rea­lized, that I enjoy pro­gram­ming and sol­ving pro­blems even more than in­stal­ling and confi­gu­ring hard­ware, e.g. secu­rity sys­tems and compo­nents of data centers. I went on to pur­sue this ca­reer and in Octo­ber 2016 I star­ted to study com­puter science in Berlin. After my first semes­ter I al­ready got my first job as a part-time web deve­loper, where I mostly worked with Wordpress and Bootstrap. I wanted to learn more and gain first profes­sional expe­rience as a deve­loper and I am glad, that I had made this deci­sion, be­cause I learned a lot!

After that in 2019 I did an abroad internship in Portugal, which lasted 5 months. I worked in the Lisbon area at Primetag, a portuguese SAAS company in the influencer marketing business, where I developed a dashboard and testing system for the company to manage all their end-to-end tests for their platform using React and Node.js. The next thing I am looking forward to is to dive deeper into JS territory and do more fullstack development!

Projects & Work

These are some of my web de­ve­lop­ment side pro­jects and uni­ver­si­ty pro­jects. Du­ring my time at the uni­ver­si­ty I al­so did ma­ny other pro­jects using Java, which co­vered to­pics like al­go­rithms, data struc­tures, image pro­cess­ing, unit tes­ting etc.. You can find some of these on my Github profile.


Cydash is a webapplication to manage end-to-end tests which I have built during my internship at Primetag in Portugal in 2019.

React, Redux, Node.js,,

Private due to being an internship project, though you can take a look at the demo!


Overlays is a university project which I did together with Luisa Kurth. The goal of this game is to give the player a better intuition for overlapping colors. The game gets more difficult with each level!

jQuery, Bootstrap, Sass, Canvas API, Node.js
