About

Professional summary

I am a customer support and technical support professional with experience assisting English-speaking customers through email, phone, chat, and social media. I focus on clear communication, empathy, accurate case handling, and practical problem-solving.

I have supported customers with account access, login credentials, password resets, multi-factor authentication, and other basic technical enquiries. I document interactions thoroughly, create and update tickets, and escalate complex cases when needed.

My background also includes operations support, database record checking, field-agent registration coordination, and monthly reporting. I am comfortable maintaining central management systems and ensuring information meets compliance requirements.

I have practical technical experience in computer hardware, software installation, troubleshooting, networking, fault diagnosis, and computer repairs. As a business owner, I have combined customer service responsibilities with computer sales and technical support.

I am proficient with customer support and customer data systems, including Zendesk, DFM Ticketing System, Conversocial, and SAP Customer Data Cloud. I also use Microsoft Office applications for documentation, reporting, and communication.

I am seeking opportunities where I can apply my customer service, technical troubleshooting, ticket management, and operations support capabilities to help customers and teams achieve effective resolutions.
