Summary
👤
Senior🎓
Top SchoolVitalii Prozapas is a backend developer with 11 years of experience building high-throughput Java microservices and cloud-native systems, currently improving a global CPaaS platform from Alicante, Spain. He combines deep Java/Spring expertise (Spring Boot, WebFlux, Quarkus) with practical experience in Kafka, Redis and SQL/NoSQL to deliver measurable gains—reducing technical debt, cutting infra costs, and improving latency and throughput in production. Vitalii has repeatedly led migrations from monoliths to microservices, designed fault-tolerant event processing that handles 100K+ concurrent fallback events daily, and has a product-minded approach that ties architecture choices to business impact. Comfortable across AWS, Azure and GCP, he also brings hands-on experience integrating payment and third‑party APIs in B2B SaaS contexts and shipping zero-downtime releases across diverse customer infrastructures. Not obvious from titles alone: he consistently drives both operational cost optimizations and security improvements, reducing authorization incidents while boosting platform stability.
