Summary
Sergiu Breban is a Senior Full Stack Engineer with 11 years of experience specializing in Java back-end, cloud infrastructure and React-based web UIs, delivering high-performance systems for healthcare, trading and HPC customers. He combines deep distributed-systems knowledge (Masterโs in Distributed Systems) with hands-on expertise in Spring Boot, AWS, Docker, MySQL and messaging middleware to dramatically improve throughput and reliability in production services. As a contractor and freelancer focused exclusively on remote work, he has repeatedly reduced processing times and defect ratesโe.g., cutting data-load times from 30s to under 3s and slashing delivery time for platform rollouts by 90%. Sergiu is comfortable across the full stack and infrastructure layers, from designing exchange simulators and high-throughput message translators to building cloud-native healthcare portals with strong data security controls. Pragmatic and metrics-driven, he favors root-cause analysis and reusable components that scale across teams and products.
