Summary
👤
Senior🎓
Top SchoolJonathan Fernández is a seasoned Support Escalation Engineer specializing in Azure Linux with over two decades of hands-on experience in UNIX-like systems and 10+ years in enterprise support roles. At Microsoft he focuses on complex troubleshooting, system recovery, boot and custom-install issues, and optimizing cloud infrastructure for reliability and performance. His deep roots in HPUX, AIX, Solaris and long-term Linux practice since 1997 give him a rare cross-platform perspective that informs performance tuning and HA remediation. He has led UNIX delivery teams, driven ITIL-based process improvements, and coached peers through the Azure Linux Academy to elevate team technical proficiency. Jonathan combines practical automation and tooling experience from roles in SRE and large-scale Linux operations with a continuous curiosity for improving documentation and operational workflows. Based in Costa Rica, he pairs pragmatic incident ownership with a mentor’s mindset, often surfacing systemic fixes rather than one-off patches.
