SaaS
Sweep Stake - Wheel Game
Gamification Platform with Admin Portal
Executive Summary
The Situation:A marketing SaaS company required a white-label gamification engine (spin-the-wheel) that other vendors could subscribe to and deploy to their own customers.
The Mandate:Architect a complex multi-tenant system: a highly interactive Flutter frontend for end-users, and a robust Next.js admin portal for vendors to customize their game mechanics and pay subscriptions.
The Result:Delivered a massive, engaging SaaS ecosystem that generated immediate recurring revenue for the client through B2B vendor subscriptions.

Technical Deep-Dive
Overcoming Bottlenecks
Engineering a secure, un-hackable wheel-spinning physics engine in Flutter where the outcome was determined securely by a backend API rather than client-side manipulation.
First-Principles Engineering
Built a cryptographic RNG (Random Number Generator) on the backend API. The Flutter app simply rendered the buttery-smooth rotation physics based on the secure, pre-determined API response, eliminating cheating entirely.
Business Impact
B2B Monetization
Integrated Stripe billing to handle automated vendor subscriptions seamlessly.
White-Label Scale
The Next.js dashboard allowed vendors to dynamically upload logos and change game parameters without developer intervention.
Cross-Platform Gaming
Flutter delivered 60fps native performance, making the gamification feel premium and addictive.
