Message

At ONEBYZERO PHILIPPINES INC., I served as an Engagement Manager for AI, digital transformation, and data analytics engagements across telco, banking, insurance, petrochemical, and infrastructure sectors. I managed cross-functional teams of up to 15 and engagements ranging from focused sprints to multi-million dollar implementations.

I advised enterprise clients and served as their primary delivery contact, while driving project financial performance and contributing to account profitability and growth. I also translated complex data and technical delivery into actionable insights for business users and executive stakeholders.

I designed process improvement frameworks, governance dashboards, documentation standards, and time-tracking systems to reduce delivery cycle times and strengthen team alignment. I also surfaced AI and voice use cases across client business units.

Earlier, at ACCENTURE, INC., I documented requirements for SAP Fieldglass and SAP Ariba implementations, led UAT, and supported an SAP Ariba go-live for a health insurance client. At REPUBLIC BISCUIT CORPORATION, I led mobile application and system-module development through rollout; at TECHNO TIME RETAILERS CORP., I developed a spare parts inventory tracking template and standardized inventory reports, reducing reporting delays from one month to one week.
