Featured Architecture & Automation
Automated User Lifecycle Management
Problem: Manual offboarding left temporary security gaps and cost hours of administrative overhead per week.
Action: Developed Python and Power Automate scripts integrated with Azure AD to automate account provisioning, expedite token revocation, and streamline Mimecast archiving.
Result: Reduced manual admin effort by roughly 5+ hours per week and reduced offboarding revocation time from manual delays to within minutes.
Hybrid Infra & Domain Consolidation
Problem: Fragmented bare-metal and cloud servers across entities caused management silos and inconsistent security configurations.
Action: Managed the consolidation of a hybrid environment (6 Azure VMs + Hyper-V) and centralized DNS/SSL certificate management to improve security oversight.
Result: Contributed to a 99.9% uptime metric and helped enforce uniform, group-wide security policies across all corporate entities.
Enterprise Mimecast DLP Deployment
Problem: The enterprise lacked unified data leak prevention (DLP) and faced increasing inbound phishing threats.
Action: Configured Mimecast Content Examination Policies, Advanced Threat Protection (ATP), and standardized secure routing rules for 100+ active inboxes.
Result: Improved email threat detection, blocking all malicious payloads used in internal testing, and enforced strict compliance data handling (POPIA) on outbound mail.
