What I'm looking for

I’m looking for a role where I can design secure, scalable cloud architectures, lead engineering teams, and build full-stack AI-enabled products—combining cybersecurity orchestration with reliable delivery and measurable cost and uptime improvements.

I’m a Strategic Solution Architect with 8+ years bridging enterprise infrastructure, cybersecurity, and modern software development. I bring Oracle Certified AI & Cloud Associate and ISC2 Certified Cybersecurity credentials, focused on designing secure, scalable architectures that hold up in production.

As a Technical Team Manager at TactfulConsult Ltd, I engineered secure, cloud-native designs for Financial, Manufacturing, and Government institutions. I lead security orchestration with Tenable Nessus and Infoblox DDI to automate vulnerability remediation, and I’ve delivered client-facing tools using React and Python backends—including a $51K Vulnerability Assessment & SIEM Integration project that went live with Tenable Nessus and closed in April 2026.

Before that, as an Enterprise Systems / Cloud Administrator, I decommissioned redundant Azure infrastructure to save $30,000 annually and managed secure endpoint onboarding with Microsoft Intune/MDM. I’ve also built and optimized architectures across Azure and AWS (including Kubernetes), strengthened identity with Active Directory/Azure Active Directory, and implemented Zero Trust using OneLogin PAM—while maintaining an engineering-first culture that improves velocity through Agile/Scrum.
