Role: Full-stack Developer (freelance, full build from client-supplied wireframes)
Summary: Spin to Win promo game: weighted prizes, eligibility rules, vouchers, CRM API and duplicate prevention.
Context: Revolution Bars, a UK bar chain, wanted a digital Spin to Win game to drive sign-ups and repeat visits across its venues, with campaigns their marketing team could run themselves. The client supplied the wireframes, and I took them to a full, production-ready build.
What I delivered:
A branded, mobile-first spin-the-wheel experience where guests enter their email to play
Weighted prize logic, so the odds of each prize can be controlled per campaign
Eligibility rules and duplicate-entry prevention to stop repeat plays and abuse
Voucher generation, management and tracking for the prizes won
CRM API integration, so every entry flows straight into the client's marketing database
A backend where campaigns, prizes, limits and odds are configured without touching code
Validation, security safeguards and full functional testing before launch
