What I'm looking for

I'm looking for a role where I can use data cleaning, reporting, and analytical thinking to improve processes, maintain accurate information, and support informed decisions.

I've supported data accuracy at CMCYS Consulting and Oclinicals by entering, cleaning, and verifying records, correcting inconsistencies, and creating reports to support analysis.

In healthcare settings, I've worked with EMR systems, reviewed insurance and medical-debt information, and assessed procedures requiring escalation. I also bring direct-sales experience, clear client communication, and advanced Excel skills.
