What I'm looking for

I’m looking for a role where I can strengthen zero-trust security operations—investigate threats with root-cause analysis, automate diagnostics, and improve SLA-driven incident response across cloud and enterprise systems.

I’m a highly analytical cybersecurity professional with 7+ years of hands-on experience optimizing secure enterprise IT infrastructure, defensive response workflows, and production databases. I focus on monitoring infrastructure health, managing identity governance, and investigating systemic threat metrics to keep operations resilient.

I transitioned into dedicated contractual and MSP consulting to support distributed cloud configurations and robust access structures across global sectors. I mitigate system gaps through deep-dive query isolation, automated diagnostics, and strict SLA compliance within zero-trust architectures.

I’m also hands-on with high-severity incident and change governance using ServiceNow, and I improve reliability by turning investigations into runbooks—highlighted by a documented 25% reduction in application downtime. In earlier roles, I reduced critical downtime by 25% through proactive monitoring and root-cause analysis, while automating repetitive diagnostics using custom Python and Bash scripts.
