Bio
Andy Klier
Denys is a highly competent developer who I have had the pleasure of working with at Zuar for the past few years. Denys possesses an impressive technical understanding at the top level in Python, Docker, and Bash, and presumably much more. His expertise in these areas is truly impressive, and he consistently demonstrates a deep understanding of best practices and industry standards. Denys has a keen eye for detail and a strong problem-solving ability, which allows him to tackle complex projects with ease. Denys' dedication and work ethic are truly commendable, even given difficult working conditions. He consistently goes above and beyond to deliver high-quality work within deadlines and his proficiency in English greatly enhances his ability to collaborate with team members.
Kenneth H. East
Denys is one of the finest software engineers that I’ve worked with, and I’ve worked with some truly exceptional ones; I can’t recommend him enough. He has led the development team for one of our products for about 1.5 years. During that time, he played a key role in the migration from a monolithic to a microservices architecture. His insight, experience, and leadership were essential to creating the flexible and scalable product our customers are using today. Denys isn’t just skilled technically — he also has a great knack for understanding the business drivers that shape what needs to go into the product. Denys is the guy I want on my team when the going gets tough.
