At Xendit, I lead end-to-end enterprise payment solutioning from business discovery and RFPs through solution architecture, API integration, implementation, and production go-live.

I've supported 100+ enterprise merchants across 100+ payment methods in six Southeast Asian markets, designing flows for cards, virtual accounts, QR, e-wallets, direct debit, payouts, tokenisation, subscriptions, and cross-border payments.

Before Xendit, I delivered regional banking and digital banking initiatives at CIMB, Cyber Village, Fusionex, Hitachi eBworx, and Astra Insurance. My work has covered corporate banking, Host-to-Host integrations, reporting, mobile banking, loyalty platforms, and enterprise applications.

I translate complex requirements into practical, scalable solutions and partner closely with Sales, Product, Engineering, Operations, Security, Compliance, and merchant technology teams to resolve blockers and deliver successful go-lives.
