Hiring Manager
Openkyber
Dear Hiring Manager,
Securing Microsoft 365 environments at scale has become second nature to me, having designed and overseen controls that protect over 20,000 users globally. Openkyber's commitment to empowering organisations through secure collaboration platforms resonates with my engineering philosophy. I optimise security without hindering productivity, and I would bring that mindset to your team.
My current role as M365 Security Architect has me partnering with cross-disciplinary teams to map security controls against business objectives. I conduct regular threat modelling sessions that translate compliance frameworks into actionable engineering requirements, keeping our Azure and Microsoft 365 footprints secure while enabling DevOps velocity.
Previously, as a Senior Designer, I led projects that blended security, compliance, and user experience. One highlight was redesigning an enterprise identity platform that reduced account takeover attempts by 40% and earned SOC 2 compliance, all while maintaining positive employee feedback on login experiences.
