What I'm looking for

I seek a senior infrastructure or cloud role where I can lead technical teams, drive large migrations and modernizations, improve uptime and security, and scale operations with automation and monitoring.

I am a Senior IT Administrator with deep experience directing enterprise infrastructure across on‑premise, virtualized, and cloud environments, supporting 300–500+ users. I design and maintain Windows/Linux servers, VMware/Hyper‑V platforms, Azure and Microsoft 365 integrations, and robust network and security controls that have improved uptime to 99.9% and reduced incidents and downtime significantly.

I lead and mentor technical teams, deliver large migrations and cloud solutions, and streamline operations through automation, monitoring, and process improvements. My work has driven measurable gains — including a 30% efficiency improvement, 25% reduction in downtime, and successful enterprise Microsoft Cloud deals — while maintaining compliance and strong incident response capabilities.
