I've built payment and e-commerce systems at GoTo Financial, Bukalapak, Garasi.id, and Goxeus, delivering integrations, platform features, and partner websites with measurable business impact.
At GoTo Financial, I increased third-party users by 3.2 million through GoPay integration, integrated two new banks, delivered a split-bill system that increased TPS by 12%, and helped modernize legacy applications for Bank of Indonesia requirements.
At Bukalapak, I integrated warehouse management with external parties to reduce distribution-center setup costs by up to 150 million IDR. I also redesigned loyalty features that grew seller participation from 28% to 93% in six months and improved active rates by more than three times.
Most recently at Goxeus, I rebuilt a partner website that increased traffic and customer engagement by 20%, then integrated email marketing that increased monthly new users by 80%. I work across Java, Golang, Python, Ruby, PHP, React, cloud infrastructure, APIs, and data platforms to turn business requirements into reliable products.
