👤
Senior🎓
Top SchoolSergey Kapustin is a pragmatic Java developer with a decade of professional experience and over three years focused on building cloud-native web applications for monitoring, analytics, and fintech. He routinely delivers backend services using Java 11/17, Spring ecosystem, JOOQ/Hibernate, PostgreSQL, Kafka and Kubernetes, and drives quality via JUnit5 tests, Liquibase/Flyway migrations and OpenAPI-driven code generation. At GlowByte he built features that visualize Kubernetes infrastructure and integrate Prometheus metrics, while earlier roles included fintech work in Kotlin and B2B portals with distributed services. Known for performance tuning, modular refactoring and cross-team collaboration, he combines hands-on coding with architecture discussions and code review discipline. An interesting thread through his career is blending ops-aware development (metrics, orchestration, CI/CD) with product-facing analytics, making him effective at turning infrastructure signals into actionable business features.
