About
Finance, Accounting, and Tax professional with 10+ years of experience across Big Four audit and corporate finance roles in technology and retail industries. I began my career at Deloitte, where I built a strong foundation in auditing, financial reporting, and internal control assessment before transitioning into corporate finance leadership roles. Currently, I serve as Finance, Accounting, and Tax Associate Manager at Quipper Edukasi Indonesia, where I oversee financial reporting, budgeting and forecasting, tax compliance, and audit coordination. My role focuses on ensuring financial accuracy, strengthening internal controls, and supporting strategic decision-making through financial analysis and clear reporting to management. Throughout my career, I have developed experience in managing end-to-end finance operations including financial statement preparation, cash flow management, budgeting, tax reporting, and audit processes. I enjoy working at the intersection of finance operations and business strategy—helping organizations build efficient financial systems, improve compliance, and drive sustainable growth. I am experienced with various accounting systems such as SAP, Odoo, Xero, and Microsoft AX, and I value collaboration, problem solving, and continuous improvement in finance processes.
