Summary
👤
Senior🎓
Top SchoolKonstantin Krylov is a Senior Java Software Engineer with 7+ years of experience designing and delivering high-load microservice systems across e-commerce, retail, and banking domains. He specializes in the Java/Spring ecosystem (including Spring Boot 3, WebFlux and Project Reactor), cloud-native deployments on GCP/Kubernetes, and pragmatic API design with OpenAPI. Konstantin has a strong track record of modernizing legacy systems, implementing reactive services, and optimizing performance via Redis caching, Kafka, and thorough testing (JUnit 5, Mockito, Testcontainers). At EPAM he helped drive a large digital transformation for a retail e-commerce platform and previously built banking microservices that improved internal tooling and operational efficiency. Now based in Valencia and working at Deutsche Telekom, he combines hands-on implementation with architecture-minded thinking and a knack for reverse-engineering complex systems. A detail not obvious from titles: he pairs reactive programming expertise with practical CI/CD and observability practices (ArgoCD, Jenkins, Prometheus) to reliably ship scalable services.
