I had the pleasure of working with Sergiy on a web project and was thoroughly impressed. He has a great eye for design, pays attention to detail, and quickly understands the task at hand. Communication was smooth, and all feedback was implemented promptly. I highly recommend Sergiy as a reliable and talented UI/UX designer.
I had the pleasure of working with Sergiy during his time as a Product Designer at SettlePay, where he made a significant impact, particularly within our crypto-related initiatives. Sergiy demonstrated a deep understanding of user experience and product design. His designs consistently reflected both creativity and clarity, balancing user needs with technical feasibility. Beyond his design skills, he was a great team player—collaborative, proactive, and always open to feedback. He worked closely with product managers, engineers, and other designers, helping to align everyone around a shared vision.
I had worked with Sergii on a large financial project in the b2b2c sphere. He played a very difficult role - take a project after 2+ years in prod and take it from only one on the project designer. I am sure, that he not only supported the high level of design, he also brought new fresh solutions and started playing over the box. Super sub) Thank you a lot!
