About

Professional summary

I am an operations and customer experience professional with more than 15 years of experience in service operations, customer support, team coordination, sales, and e-commerce. My work has focused on improving daily execution, maintaining high service standards, and creating positive customer experiences.

I currently work as an Assistant Manager at ALTERLIFE Fitness Excellence in Athens, where I lead and train a 15-member team. I coordinate daily priorities, support staff performance, address operational issues, and help deliver service to a member base of more than 1,200 customers.

I have hands-on experience in team leadership, scheduling, coaching, performance support, customer escalations, sales monitoring, and process improvement. I am comfortable working in fast-paced customer-facing environments where reliability, communication, and problem-solving are essential.

As the founder of an independent e-commerce business, I managed end-to-end operations including more than 500 online sales, customer support, order processing, supplier coordination, inventory availability, product listings, and after-sales service.

I also planned and managed digital advertising campaigns through Google Ads, Facebook, and Instagram, while maintaining website content through WordPress. My background combines operational leadership, commercial awareness, customer care, and practical digital commerce experience.

I have worked in both Greece and the United States, developing adaptability and strong professional communication in international service environments. I am interested in opportunities where I can contribute to efficient operations, team performance, customer satisfaction, and business growth.
