What I'm looking for

I seek roles where I can apply data accuracy and customer service strengths, improve processes, support teams, and grow into greater responsibility within a collaborative, client-focused organization.

I am a data analytics and customer service professional with hands-on experience in data entry, virtual assistance, and managing high-volume customer interactions. I consistently ensure accuracy when handling large datasets and contribute to process improvements that support better decision-making.

In customer service roles I managed inbound inquiries via phone, email, and chat, resolved complaints to retain client loyalty, and helped train new team members by sharing best practices for engagement. As an intern and volunteer coordinator, I organized records and schedules, assisted with data cleanup projects, and supported event logistics to ensure smooth operations.

I bring strong time management, database management, MS Office proficiency, confidentiality, and leadership skills. I am adaptable, client-focused, and committed to delivering efficient support that improves processes and fosters positive relationships.
