Top SchoolJun Ze is a security consultant and experienced backend/DevOps engineer based in Kuala Lumpur with eight years of hands-on experience modernizing Go codebases and strengthening test infrastructure across high-profile open-source projects like Podman, Thanos, Loki, and Juju. He blends vulnerability assessment and penetration testing expertise from Deloitte with practical IAM and automation work, now applying that security-first mindset at Atos. Jun’s contributions consistently focus on code modernization—migrating deprecated APIs, improving test isolation, and tightening dependency management—to make large distributed systems more reliable and maintainable. Comfortable across Linux environments and cloud-native tooling, he frequently improves CI/test reliability and fixes platform-specific issues, including Windows peculiarities. Notably, his open-source footprint spans CNCF projects and widely used tools, signaling an ability to operate at scale while keeping code quality high. He pairs a formal cybersecurity education with pragmatic engineering practices, quietly preferring subtle, high-impact refactors over flashy rewrites.
