About

Professional summary

I am a versatile Virtual Assistant with experience in administrative support, customer-facing sales, social media management, and U.S.-based medical billing. I work effectively in remote environments and prioritize organized workflows, accurate documentation, and reliable client communication.

I have supported medical billing operations by reviewing patient and insurance information, validating coding and charge details, submitting electronic claims, and monitoring claim status. My experience includes handling claim corrections, resubmissions, reconsiderations, rejections, workers’ compensation, and no-fault claims.

I bring strong sales and customer engagement skills, including rapport building, client follow-up, upselling support, and clear communication with healthcare stakeholders. I am comfortable managing sales-related records and coordinating product activities in hospital-based settings.

In social media and virtual assistance roles, I have created and scheduled content, managed day-to-day administrative tasks, maintained documentation, and supported client workflows remotely. I am adaptable and able to work independently while keeping tasks organized and on schedule.

I am detail-oriented, proactive, and committed to quality. My strengths include communication, problem solving, time management, attention to detail, organization, and adaptability.
