01
Context & Challenge
As an official Samsung Members Star, Marvin needed to distribute 1,000 exclusive Samsung voucher codes to his community. Distributing codes manually via direct messages typically takes 8 to 12 months, causing heavy administrative strain and risking vouchers expiring before reaching followers.
02
Engineering Methodology
Took his prototype from Lovable, deployed it live to production, and built a custom voucher coupon automation system connecting React, Resend email delivery, Google Sheets, and Google Apps Script.
03
Findings & Impact
Distributed all 1,000 voucher codes autonomously in just 6 months—beating the usual 8-12 month timeline by half and delivering vouchers instantly with zero manual intervention.
