What I'm looking for

I seek a role combining customer support and data analysis, in a collaborative, deadline-driven environment with growth opportunities.

I am a results-oriented customer service and administrative professional with over five years of progressive experience supporting executive teams, clinical research, and technical support operations. My background blends customer-facing roles with data analysis and medical billing, enabling me to translate client needs into actionable solutions.

I have contributed to data-driven projects—creating charts and graphs in Excel, performing analyses for study submission, and working with SQL and Tableau for reporting and validation. I am comfortable with ticketing systems, CRM tools, and remote support platforms, and I prioritize clear communication and timely resolution.

I hold a Bachelor of Accounting and certifications as a Certified Scrum Master and Certified Data Analyst. I bring strong attention to detail, adaptability, and a collaborative mindset to help teams meet deadline-driven objectives.
