Guilherme Vinicius C.
Data Entry Specialist | Admin, Excel, Denticon, Open Dental
I help businesses and healthcare teams stay organized with accurate data entry, admin support, and reliable record-keeping, the kind of behind-the-scenes work that keeps everything running without constant oversight. Over the past two years, I've worked daily in spreadsheets and management systems where accuracy was the whole job. In my dental operations role, I managed insurance verification for up to 8 offices at once, covering roughly 5,600 patients a month, led a team of 6, and built SOPs and onboarding systems from scratch. I'm experienced in Denticon and Open Dental, and comfortable picking up new tools quickly. What I bring to clients: Data entry and accurate record-keeping across systems Spreadsheet work in Excel and Google Sheets Process documentation and SOP creation Insurance verification and eligibility management (dental) Clear, professional communication with clients, teams, and partners I care about building systems that hold up under volume, not quick fixes. Whether you need steady data entry, admin support, or someone who knows dental insurance workflows inside out, I'd love to help keep your work accurate, organized, and running smoothly.
