"comment": "I had the pleasure of working with Sergey for five years at Remedy Product, during which he grew from a senior engineer into a trusted and capable tech lead. As Head of Product, I collaborated closely with Sergey across multiple projects, including Vend Park. I consistently relied on his diligence and technical skill to bring complex ideas to life.\n\nSergey is a reliable and hardworking engineer. He approaches every challenge with care and professionalism, and he leads with both competence and kindness. Beyond his technical contributions, he’s a team player who brings loyalty, integrity, and a steady presence to any team he's on.\n\nAny organization would be lucky to have Sergey."

"comment": "Sergey worked closely with Vend Park via Remedy Point Solutions. Over the course of about 2 years, he implemented a lot of our core backend functionality. Sergey's communication was incredible, and he was able to fully understand intricate business requirements and convert them to reliable and scalable code. \n\n Specifically he demonstrated proficiency across a variety of Google Cloud Platform tools, built a robust and scalable serverless backend, helped with data migrations and one-off user requests, and was always available for emergencies even over weekends. He led several projects including (for example) the implementation of complex pricing algorithms working across timezones and DST, as well as hierarchical application of parking passes and time-based parking rates specific to each garage and each user. \n\n Overall, I really admire Sergey's attitude and approach to problem-solving. He is much more than a typical backend developer - he is someone your team can count on as a backend lead that spans everything from project planning through to detailed implementation and maintenance. In addition, he provided oversight and acted as the team lead for about 6 engineers spread between mobile and web technologies. \n\n Thank you for your hard work Sergey!"

"comment": "I feel very lucky to have worked with Sergey and I want to sincerely recommend him.\n\nSergey is an incredibly strong backend developer and architect, and a true driver of the team. His expertise and experience help not only to solve complex tasks but to do so in the most effective way. If Sergey notices a problem, he never just points it out — he always suggests a solution. What’s more, he has the rare ability to see potential pitfalls and risks at the earliest stages of a feature’s discussion or development, which saves the team a huge amount of time and effort.\n\nI especially appreciate his willingness to share knowledge. Every call with Sergey feels like a mini masterclass: he doesn’t just explain the task, he helps you truly understand the bigger picture. Over two years of working side by side, I’ve learned more about API testing from him than I did in several years of independent practice.\n\nSergey is that rare kind of professional who combines strong technical expertise with kindness, willingness to help, and real team spirit. Working with him is a great pleasure and a big advantage for any company."
