What I'm looking for

I’m looking for a role where accuracy, timely processing, and excellent service matter. I want to apply my lab data entry and medical billing/coding training while supporting smooth day-to-day operations and a team-focused environment.

I’m a versatile, dependable professional with a diverse background in healthcare support, retail management, and customer service. I’ve handled high-volume, detail-driven work—ranging from laboratory data entry to front-line guest service—while keeping quality and accuracy consistent.

In hospital settings, I streamlined laboratory workflow by accurately entering patient data and sample information into the hospital database. I also operated specialized diagnostic machinery and prepared pathology slides for physician review, supporting timely results for clinical staff.

Beyond healthcare, I delivered service excellence in fast-paced retail environments for many years, processing returns, exchanges, and money orders at the service desk. I managed inventory stocking, price changes, merchandising, and technical customer requests like mixing paint, cutting keys, and measuring/cutting fabrics.

As an assistant manager, I coordinated daily operations through staff hiring, firing, and training, while maintaining financial integrity through secure cash drops, bank deposits, and detailed daily paperwork. I’m especially proud of my track record in records management, vendor relations, and safety compliance—ensuring smooth operations and a welcoming, reliable experience for every client and guest.
