Kiryl Kavalenka

Senior Product Designer

Hey, I’m a designer with 7 years of experience.

Currently, I’m a Senior Product Designer at StarOfService with a focus on product growth.

I'm used to a Swiss army knife role—besides the design activities, I dive deep into data analytics and research, pitch ideas and write a bit of code to tailor elegant and efficient solutions for complex systems.
