Summary
👤
Senior🎓
Top SchoolSergei Ignatov is a seasoned Software Engineer with over 15 years of experience designing, optimizing and troubleshooting large-scale Java EE systems, currently contributing at Walmart Global Tech from San Jose. He has deep expertise in performance profiling, refactoring and architecture—demonstrated by scaling high-throughput government procurement systems and doubling contract-creation throughput through targeted optimizations. Comfortable across the stack, Sergei leverages Spring Boot, Hibernate, Oracle and WebSphere while also drawing on earlier work in C++, Groovy and client-server synchronization for complex integrations. He blends hands-on coding and daily code review with cross-team collaboration (analysts, QA, infrastructure) and on-call DevOps troubleshooting. Sergei pairs an MS in Computer Science with recent MS-level software engineering studies, and brings a pragmatic focus on measurable performance gains rather than theoretical design alone.
