Projects led by DDITA’s principal engineer in senior engineering and technical-lead roles at enterprise employers. Scope and outcomes are described without naming the organizations or disclosing their internal configurations.
Full-stack Cisco Meraki ecosystem migration
Enterprise modernizationExecution. Led a cross-functional engineering team replacing fragmented legacy edge hardware with a unified cloud-managed Meraki fabric: SD-WAN, enterprise switching and next-generation security rules in a single dashboard.
Impact. Standardized network delivery templates, shorter edge deployment timelines, centralized visibility across global operations, and zero-downtime cutovers during critical business hours.
Cisco ASA to Palo Alto NGFW consolidation
Acquisition integrationExecution. Technical lead for harmonizing edge security across several corporate entities acquired by the parent organization. Directed a distributed consultant team through discovery and mapping of legacy ACLs, translated them into Palo Alto Layer-7 application and user-aware profiles, and enforced unified policy through Panorama.
Impact. Eliminated vulnerabilities inherited from acquired sites, standardized corporate VPN terminations and unified the edge security posture.
ClearPass authentication remediation through automation
Root cause analysisExecution. Built custom Python libraries that query API endpoints and ingest real-time RADIUS and authentication logs. Automated log correlation isolated a flawed Group Policy Object being pushed to all wired and wireless clients.
Impact. A 70% reduction in authentication failure events after remediation, stabilizing endpoint onboarding and cutting NOC overhead.
Zero-touch security device provisioning
Python automationExecution. Designed modular Python automation for the security device provisioning pipeline: hands-free ZTP for physical and virtual Palo Alto NGFWs and Cisco ASAs, generating site-specific XML and text configurations, baseline security policy, encrypted VPN and local routing.
Impact. Edge firewall build time dropped from multiple days of engineering labor to single-digit, error-free automated hours.
Azure Firewall policy administration at scale
Cloud securityExecution. Engineered network security policy across a multi-tenant public cloud footprint using Azure Firewall and Azure Firewall Premium, applying Infrastructure as Code alongside native cloud shell configuration for NAT, application and network rule collections bridging cloud compute to on-premises data centers.
Impact. Continuous automated sync checks keep rule changes consistent across all global regions, maintaining operational compliance.
