84 Units Sold (@ IDR 166M) · ~IDR 13.94B GMV · Role: Digital Advertiser & Lead Acquisition (Mortgage KPR, admin, & akad managed by developer team).
In strategic collaboration with property developer PT Bagus Permata Biru, I directed paid digital buyer acquisition campaigns for residential housing units priced at IDR 166,000,000 per unit, generating approximately IDR 13.94 Billion in gross transaction value (GMV) across 84 completed unit sales.
My responsibility was strictly focused on performance marketing and lead generation: orchestrating targeted paid media funnels and qualifying prospective buyers. Back-office administrative filing, mortgage bank approval processing (BRI, BTN, BNI, Mandiri), and official notary deed signings (akad) were managed entirely by the developer's internal team.
