Top SchoolVadym Lopatka is a founder and experienced software engineer from Kyiv with 11 years building resilient, event-driven microservices and high-performance backend systems. He led architecture and delivery as Lead Engineer on a trading CRM—shifting it to an event-based design, boosting performance by 25% and halving build times—then helped shape secure Mobile ID and e-commerce platforms earlier in his career.

Strong in Java/Kotlin, Kafka, Spring ecosystems, Kubernetes and CI/CD, he blends hands-on coding with team leadership, XP/TDD practices and developer onboarding. Colleagues describe him as an engineer who turns complex domain requirements into auditable, testable systems and who quietly optimizes developer workflows as well as production performance.
