Senior Solution Architect at Hawk Cyber Security who deployed Zero Trust and cut security-alert false positives by 30%.

At Hawk Cyber Security, I support the design, implementation, and documentation of solutions across WAN, LAN, and cloud environments. I led end-to-end Zero Trust deployments across hybrid cloud and on-premises environments, and created Microsoft Sentinel dashboards and correlation rules that reduced false positives by 30%.

Across my work at Hawk Cyber Security, BCG, and INFOSYS, I’ve designed network and security solutions using Cisco, Azure, and SD-WAN technologies. Earlier, at Federal Home Loan Bank, I led a team of five engineers and authored a disaster recovery plan supporting 95% recovery time for all components.
