Work Experience
QA Tester
Jan 2023 - July 2023
Kool2Play
Functional and exploratory testing during development of a twin-stick shooter URAGUN
Clear bug reproduction, documentation, and communication with developers
Provided structured gameplay feedback alongside QA duties
One gameplay/weapon trait proposal implemented into the final release
Worked directly with the dev team close to 1.0 launch under time pressure
I had worked with Jarek for several months prior to the Uragun 1.0 launch, and I must say that he is one of the most dedicated and hardworking folks I have cooperated with. His passion for games is tangible, and his eye for detail is superb. He had a real influence on the final quality of our game, and we owe him a lot! He is one of those guys who embodies great determination and deserves a chance in the game development industry.
