I build resilient cloud platforms and lead global SRE engineering teams.
United KingdomWhat I'm looking for
At Mimecast, I lead a global Platform Engineering organisation responsible for SRE, AWS cloud infrastructure, reliability, and security compliance for a security product suite. I built a follow-the-sun support model across the UK, Poland, and India, cutting response time by 20% and raising response SLA to 99%.
I previously scaled Entegral engineering from 7 to 25 people while delivering cloud, desktop, and mobile products end to end. By re-architecting core infrastructure, I increased cloud platform capacity 10x without a corresponding increase in operating cost.
Across nine years at Cisco, I progressed from Engineering Manager to Senior Engineering Manager and led secure collaboration platform infrastructure for 4,000+ internal users at 99.9% uptime. My automation work improved engineering efficiency by 20%, while Secure SDLC improvements raised compliance by 80%.
I combine hands-on platform engineering across AWS, Kubernetes, automation, and secure delivery with MBA-backed commercial leadership. I enjoy building capable global teams, reducing operational risk, and aligning engineering strategy with product and business outcomes.
