What I'm looking for

I’m looking for a billing/back-office role where I can own accounts receivable and collections, ensure deadline-driven accuracy and compliance, and use KPI analysis and procedure manuals to improve cycle times, reduce errors, and strengthen client support.

I’m an Industrial Engineer and Quality Specialist who’s built my career around accurate billing and back-office financial operations. I support accounts receivable and billing across multiple regions—focused on compliance, deadlines, and clear client communication.

In my accounts receivable roles, I manage end-to-end billing cycles, invoice delivery, billing disputes, and adjustments while keeping financial records accurate. I also work with financial databases such as Finalli and QWS to support verification and reconciliation.

I drive measurable improvements through analytics and standardized processes. For example, I reduced monthly closing time by 20% with an Excel-based tool, cut accounts receivable tracking time by 40% through training, and increased control and verification of critical data by 80% through weekly and monthly audits.

Across larger billing environments like UPS, I improved Amazon’s billing process and created procedure manuals that increased accuracy and efficiency by 80%, while also streamlining authorization response time in Mexico from 1 week to 3 days. With ISO 9001:2015 Lead Auditor certification, I bring a quality-first mindset to every billing and reporting operation.
