What I'm looking for

I'm looking to lead revenue assurance, billing, finance operations, or data-driven process improvement work where I can strengthen controls, automate reporting, resolve billing exceptions, and improve operational performance.

At Valueonshore Advisors supporting AT&T, I manage end-to-end billing validation, reconciliation, and revenue assurance to prevent leakage and support accurate revenue recognition.

I build automated Power BI dashboards and KPI models that help leadership monitor revenue trends, wholesale metrics, billing performance, and operational exceptions. I also partner with project managers and cross-functional teams to investigate escalations and maintain internal-audit compliance.

Previously at Tata Communications, I re-engineered billing workflows to sustain a 99.5% on-time billing SLA and reduced invoice-on-hold instances by 15% through root-cause analysis and data validation.

At British Telecom, I helped eliminate 5 million minutes of rating and billing errors and automated Excel and Power BI reporting, saving one FTE of recurring effort while improving billing workflow efficiency by 25%.
