Throughout my career, I have been recognized for transforming complex business requirements into robust technical solutions that deliver significant business value. Notable achievements include spearheading a system revamp at PT Extramarks Education Indonesia, optimizing payment systems to handle double the concurrent transactions, and implementing an automated daily reconciliation system that minimized human errors.
