I manage a globally diverse, fully remote team of security professionals and traditional DevOps engineers. We build security focussed automation, and build tools to enable the security team to respond more effectively to security events in a complex multi-cloud environment that encompasses approximately 8000 AWS accounts, and 600 Azure subscriptions. We also build custom tools to support the organization's compliance efforts (NIS2, EU Cyber Resilience Act, CISA recommendations, and US Executive orders), and work with the FinOps teams to identify efficiencies.

Infor is an ERP software company, with approximately 17,000 employees globally. I worked as part of the corporate architecture team. My job was to design, test, implement and document solutions so that they can be consumed and managed by the Network team.I am an escalation point for my colleagues during incidents or outages. I have also acted as lead responder during major security incidents.Remote Access - Designed and implemented a highly scalable, highly available remote access solution using AWS Route 53 Geolocation and Cisco Anyconnect - Automated configuration using python and Jinja templates - Using this architecture, our team tripled remote access capacity in 5 business days without service interruption. This allowed a rapid shift to work from home at the beginning of the pandemic. This remote access service has had 100% uptime since it was put into production. - Automated capacity monitoring, alertingNetwork automation - Dynamic discovery of ~2000 devices across a 130 site multi-vendor network using custom python scripts (netmiko, nornir, genie/pyats/textfsm parsers) and API integration. - Configuration backups to Gitlab using Ansible. Automated reporting on configuration changes.Security Automation - Created a custom script that correlates data from multiple internal security tools and external threat sources and then identifies the most severe threats based on risk - This allowed our team to accurately identify compromised devices and prioritise remediation. It reduced reporting time from seven days to a few hours, and contributed to a >97% reduction in malware infections in ~3 months WAN redesign - Designed and implemented a redesign of branch office WAN that improved availabilty, redundancyIPAM automationNGFW DeploymentSplunk CloudVulnerability ManagementMonitoringTrainingEDR (Cisco AMP for endpoint, Crowdstrike Falcon)Cisco Umbrella
