Message

At Superior CS Group, I lead and coordinate the billing and collections team and prepare aging analyses to support cash management and cash-flow planning. I also reconcile bank and account balances across multiple entities and compile monthly financial statements.

I automate processes with Excel Power Query and AI tools such as Claude, and prepare management reports and payroll projections. I also onboard and train new employees and standardize procedures.

Previously, at Iron Mountain, I managed revenue, billing, collections, and aging reports for LATAM countries, and reconciled revenue accounts including deferred revenue and accruals. At the U.S. Embassy in Venezuela, I reviewed and recorded vendor invoices in Oracle ILMS, developed payment-process procedures, and supported regional finance teams.
