Work Experience

PowerPlay Studio, Bratislava — Medior Game Designer

Dec 2020 - current

Initially Powerplay hired me to help them develop new game concepts, but then Covid hit and we had to reorganize to strengthen our existing titles. There I was soon developing game events for live ops, helped expand existing features and also tried working as a game analyst for a while. Currently I am working as a designer on Athletics Mania where we are designing new features for guilds.

Charged Monkey, Bratislava — Game Designer

Jun 2018 - Jun 2020

I worked for Charged Monkey as a generalist designer, first as a part of a designer team and later when I showed my ability to self manage, create vision and design I was given the opportunity to be a designer on a hero collecting RPG game. There I was responsible for weekly planning, balance, level design and systems design. While this was the most fun I ever had working on a project and I am really proud of what we achieved, the project was scrapped in early alpha stages and with it I decided to leave the company.

Pixelfederation, Bratislava — Game Designer

Jan 2016 - Apr 2018

As a junior designer I started working in a new division of the company focused on Match 3 titles. During this time I found out that I really enjoy system design and balancing, on which I started to focus. While working on the first title I managed to move from a junior position to medium position.Sadly both titles had little success, so during the preproduction of the third title the company closed the match 3 division and with that we said goodbye.

Pixelfederation, Bratislava — QA Tester

Sep 2014 - Jan 2016

I worked as a tester for several Facebook and mobile games. The most prominent being Trainstation. From the position of junior tester I slowly worked myself up to lead and plan manual testing.
