Yevhen S.
lead / senior software engineer
Over the past 12 years of professional Java development, I have taken on various roles in projects—including developer, mentor, conference attendee, and tutor for beginners. My overall Java enterprise experience includes building clientserver applications, working with concurrent systems, implementing high-load system strategies, and conducting unit, integration, and end-to-end testing. Most of the projects I’ve contributed to were in the pharmacy, healthcare, and financial sectors. I have worked with a wide range of frameworks, including Spring Infrastructure, Micronaut, Quarkus, and traditional J2EE. Each project involved developing scalable and modular applications tailored to the specific strengths of the framework. Additionally, I have designed and implemented concurrency solutions to ensure performance, thread safety, and efficient resource utilization in multi-threaded environments.
