Summary
👤
Senior🎓
Top SchoolSergejs Visockis is a pragmatic software engineer with 11 years in production-grade distributed systems, and over 7 years focused on cloud-native microservices across insurance, cybersecurity, transport and trading domains. He specializes in JVM-based backends (Java, Spring, Jakarta EE) and AWS Kubernetes platforms, with a strong emphasis on reliability, performance tuning and observability in high-availability environments. Sergejs routinely owns features end-to-end—from architecture and data models to CI/CD, monitoring and on-call support—and has led migrations (CodeCommit/EC2 to GitLab/EKS) and major data migrations delivered faster than planned. He has hands-on experience solving low-latency JVM issues (e.g., ~40% memory reduction) and building integrations for large enterprise systems (GraphQL, SOAP/REST, Kafka). Based in Stockholm, he pairs mentoring and cross-functional collaboration with a bias for pragmatic, production-ready solutions that reduce operational cost and complexity. An unspoken strength is turning legacy systems into observable, maintainable platforms that scale in production.
