Summary
Stanislav Bieliaiev is a Senior Software Engineer based in Valencia with a strong track record of building and modernizing microservice platforms using Java, Spring, and cloud-native technologies. Over multiple GlobalLogic engagements he migrated legacy C and older Java codebases to Java 17, containerized services with Docker and Kubernetes, and moved critical systems to AWS (EC2, S3, EKS, RDS) while improving authentication to STS/IAM or Keycloak. He routinely drives 80–90%+ unit and integration test coverage, refactors synchronous workflows to asynchronous for performance, and implemented chunked uploads and other resiliency improvements to handle large files safely. Experienced in both backend Python stacks and Java ecosystems, he contributes to architecture, mentoring, POCs, and operational automation with ArgoCD and CI workflows. Comfortable leading end-to-end MVPs and integrations for healthcare, GenAI, and financial systems, he combines pragmatic delivery focus with a habit of documenting and knowledge-sharing across teams. A detail that often goes unnoticed: he repeatedly turns migration and refactor efforts into opportunities to raise test discipline and reduce operational risk across the product portfolio.
