What I'm looking for

I’m available for full-time or part-time remote roles and I’m ready to support operations, client relations, and accounting tasks—working across U.S. Central or Eastern time zones with an immediate start.

I’m a Finance and Accounting graduate currently working as an Administrative Coordinator, where I support daily operations across multiple company branches and keep communication flowing between teams.

I manage client outreach and follow-ups through phone and messaging, and I help strengthen relationships while staying organized with accurate business documentation. I’m also comfortable drafting formal communications, contracts, and correspondence with clients and vendors.

In previous roles, I provided administrative support to university departments—handling schedules, documentation, event logistics, and acting as a point of contact for students, faculty, and external stakeholders.

On the accounting side, I supported senior accountants with bookkeeping, tax preparation support, and financial reporting for multiple clients, processing invoices, receipts, and expense reports while maintaining compliance with Mexican fiscal regulations (SAT) and audit-ready records.
