About.
“Think Different”
– Steve Jobs
Dynamic Operations Manager with extensive experience in leading high-performance teams within the Internet and technology sectors. Currently overseeing market operations for Greece, I am dedicated to advancing our operational metrics, enhancing customer experiences, and ensuring consistent achievement of KPIs through strategic data analysis. With a robust background in Information Security and Digital Forensics (MSc from the University of East London) and Computer Science (BSc), my expertise extends to operational excellence, regulatory compliance, and environmental safety in collaboration with Facilities and Environment Health & Safety teams.
I am committed to defining and implementing robust operations strategies that optimize vehicle deployment and workforce efficiency. This includes preparing requests for proposals (RFP), monitoring competitors, and driving regional operational improvements. As a strategic liaison with government officials and key stakeholders, I foster relationships, ensure compliance, and spearhead community and safety initiatives.
Passionate about cultivating a positive, inclusive, and safe work environment, I focus on attracting, developing, and retaining top-tier talent, ensuring all team members are aligned with our mission and values. Beyond my professional endeavors, I am also an avid football enthusiast, actively participating as a goalkeeper for a local team.
