Sergei is a very talented, versatile, and hardworking UX designer. He has vast design experience and his technical capabilities are outstanding. He is very detail-oriented and always delivers high-quality work. I worked with Sergei on some very complex projects and he always delivered excellent results on time. There are very few UX designers that are good in both UX design and Front-End development but Sergei has this unique ability to deliver on both fronts. Sergei's unique skill set makes him a valuable asset for any company. He is very knowledgeable and has a brilliant attitude. He contributed to the team through his professionalism and passion. It was an absolute pleasure to work with Sergei. I wish him all the best in achieving his goals and dreams.

Sergei and I have worked on multiple projects together here at Quotit (National General). Sergei's natural ability to dissect a problem and work through ambiguities has been a big asset to our team. He is able to grasp a proposed vision quickly and run with it. Aside from his top notch design skills, what really makes him shine is his ability to think big. Sergei is constantly thinking about the customer experience and finding new ways to innovate. Many of my projects have been initiated by Sergei's insights, where he has been able to take a simple observation and craft an entire customer strategy for us to implement. H has single-handedly driven incremental revenue for us just through his ability to think strategically and act on it.

I had the pleasure of working closely with Sergei. Sergei initially joined our team as a UX designer, but he quickly demonstrated great ability to adapt and learn.One of Sergei's most impressive achievements was his rapid mastery of React and front-end development. Not only did he design impeccable UI mock-ups, but he also took the initiative to dive into front-end development, seamlessly implementing his designs. His contributions have been invaluable to our team, and I have no doubt that he will excel in any endeavor he undertakes. It's been a pleasure working alongside Sergei, and I wholeheartedly endorse him for any role that requires either UX design or front-end development expertise.

Working with Sergei at Gettr was awesome. He was a Senior UX/UI Designer for our desktop and mobile apps, and he really knows his stuff. Sergei made our apps easy to use and look great. It's not just about making things look pretty for him; it's about making them work well for our users. What's really cool about Sergei is not just his skills but how he is with people. He listens, really listens, and his ideas always make our work better. He's always learning new things and making sure our apps are the best they can be. But more than that, Sergei is just a great guy to have on the team. He's positive, works well with everyone, and always keeps us moving forward. Any team would be lucky to have him. He's not just about making great designs; he makes the team better, too.
