Passionate about creating long-term value for organisations through delivery of cyber-secure, human-centric transformation solutions, focussed on bridging the digital divide between complex technologies and end-consumer. Having successfully led cross functional teams of well over 200 personnel in strength, across my career in the military, and having drawn a deep sense of satisfaction understanding and solving complex human centric problems, I see myself as a strong people manager. All the years of experience in zero tolerance environments, be it aviation, ground based defence or cybersecurity, crafted me into a disciplined professional with attention to detail, resilience and perseverance to see a project from start to finish with desired results and prescribed quality. These ingrained habits enabled me to consistently manage and nurture high performance teams.
