Senior🎓
Top SchoolJohn Gutierrez is an Associate Software Maintenance Engineer with a decade of experience delivering reliable, high-performance solutions across healthcare, enterprise, and consulting contexts. Skilled in C#/C++, .NET (Core & Framework), SQL, Docker/Podman, and Azure DevOps, he has a track record of optimizing systems—reducing EF Core query times by up to 50% and streamlining CI/CD workflows. He combines hands-on debugging and customer-facing support (now at Red Hat for APAC RHEL customers) with practical engineering—writing scalable back-end APIs, improving async/multithreaded flows, and producing clear documentation. Comfortable working with legacy stacks and modern toolchains, he leverages automation and AI to cut repetitive work and improve code quality. Based in Metro Manila, he’s a fast learner open to expanding into languages like Java, Python, and COBOL, and brings a pragmatic focus on user-facing reliability often overlooked in pure engineering summaries.
