CASE STUDY · 5 O'CLOCK
A complete rebuild of 5 O’Clock — new Flutter mobile app, NestJS service layer, and Next.js vendor panel shipped in four weeks with zero data loss.

“5 O’Clock is a modern social dining, nightlife discovery, and rewards platform that connects users with restaurants, lounges, bars, and entertainment venues through a single mobile-first ecosystem.”
Users can browse venues, assess the vibe before they leave the house, scan bills to unlock points, leave social reviews, redeem rewards, and check in to live experiences — turning a normal night out into an interaction loop with the brands they visit.
For operators, the platform ships a dedicated vendor management system: listings, offers, redemptions, customer engagement, and real-time analytics — so every venue can run promotions, track repeat customers, and manage day-to-day operations from one place.
When the project came to us, the previous platform had stalled. The app suffered from poor performance, vendor integrations were missing entirely, the legacy architecture was unstable, and the client was facing a hard four-week deadline before a public relaunch. We rebuilt the platform end-to-end on a modern stack — Flutter for mobile, NestJS for services, Next.js for the vendor panel — without losing a single legacy user during the migration.
The result is a faster, more stable platform with a fully working vendor ecosystem, scalable infrastructure ready for peak dining-hour traffic, and a relaunch that landed exactly on schedule.
