Message

At MAXEON SOLAR PTE LTD, I govern a global Oracle ERP platform across 12+ countries and manage an architecture with 50+ business-critical integrations. I also led a migration of 90% of legacy on-premises infrastructure to AWS.

I directed the rollout of a Coupa ERP platform and designed Oracle IAM capabilities for role-based access, automated user lifecycles, and SSO/MFA. I’ve also served as AI Transformation Lead, connecting emerging technologies with legacy corporate finance infrastructure.

Previously, at NTT DATA SINGAPORE PTE LTD, I directed Oracle ERP service delivery and supported multi-country implementations. Earlier, I led an Oracle ERP upgrade finance track at ACCENTURE SINGAPORE and worked on enterprise application support, consulting, and financial systems at other organizations.
