Radovan in a few words

I am a code enthusiast with over 7 years of experience in web development for mobile and desktop devices. With a passion on modern development and clean code, I have a huge contribution in building great, high quality products. I contribute in every phase of development, from developing products to mentoring and managing teams.

My calm and relaxed personality helps people to enjoy being around and to stay relaxed in my presence too. I motivate others, share my passion, and part of me is to relate with people and manifest their virtues. Putting things in perspective is my way to answer many unclear questions.


About You & Co. KG


Web Developer  - As a freelancer

Hamburg, Germany

October 2020 - September 2021 (11 months)

I was responsible to build and maintain the CMS used internally and from external clients. My main work was on the client side with React, but I had a big impact in improving both, the product and developer experience in general. During the contract, I played a big role on reducing the build time, implementing E2E tests in the pipeline, enhancing the code quality and testing coverage and in general improving the look and feel of the application.

August 2020 - September 2020 (1 month)

I was working with Wertfaktor on couple of smaller projects but the main one was Calculator for selling house partials. Easy usage by producing a WordPress plugin (creating a zip in the CI after each change which is easily uploadable to WP). Drastic UI and UX improvement including smooth animations and consistent design (had a massive conversion growth without a single bug based on the feedback I received). Developed with high quality code and 100% testing coverage.
