Bilingual operations professional delivering virtual assistance, project coordination, and billing KPI performance.
What I'm looking for
I’m a bilingual business management professional focused on virtual assistance, project coordination, and administrative operations—especially billing, invoicing, and KPI-driven performance. I bring a practical, leadership-ready approach to organizing workflows, supporting remote teams, and keeping cross-functional work moving with clear communication and structure.
In my most recent role as a Billing & Collections Supervisor, I supervised a team of 10 billing specialists and improved invoice-processing time by 50% in a hybrid work environment through digital collaboration. I built KPI dashboards to monitor billing accuracy and operational performance, coordinated with finance, sales, and operations to improve payment cycles, and implemented a new billing system that reduced both processing time and operational errors.
Before that, I strengthened my project and executive support capabilities as a Project Coordinator and Executive Assistant to the CEO, managing timelines, tasks, and follow-ups on strategic initiatives while liaising between leadership, internal teams, and external stakeholders. Earlier, as an Administrative Assistant (including roles supporting settlements, document control, regulatory documentation, and monthly KPI reporting), I developed a strong operational foundation—and I continue to leverage tools like Microsoft Excel, SAP, MS Project, Power BI, Trello, Notion, and Google Workspace to deliver measurable results.
