Bio
Onur Tekin
I had the pleasure to work in the same project with Marcin. He is enthusiastic and hard-working, self-motivated, and always prompt to learn whatever is necessary to get the job done as planned. Marcin managed to optimize the app delivering high quality React code, covered with necessary tests. As a person, he is adaptable, works very well both in teams and autonomously, always with a smile on his face and an injury on his back.

I had a pleasure working with Marcin when I had a deadline coming too soon. He was able to provide a couple of great developers who saved the day! Not only could I get extra hands from Marcin, he also helped me to find flaws in our process and gave some advice on how to improve it. Thanks for everything Marcin!
