We needed more than a pretty UI — on-demand fuel means live GPS, dispatch, Razorpay, and four surfaces that stay in sync. They owned the full stack from concept to stores. Six months in we were past 12K downloads with a 4.7 Play Store rating; the ops dashboard alone saved our team hours every day.

Live cricket plus real-money contests is unforgiving — questions have to fire on real wickets and boundaries, not ten seconds later. They built the event-to-question pipeline and the broadcast layer so hundreds of thousands of users get the same moment at the same time. That is not a feature you patch in later.

Fantasy cricket breaks on match day, not in Figma. We needed live score ingestion, leaderboards that update ball-by-ball, and settlement people trust. They architected for the spike before our first India match — Redis leaderboards, dual-source scoring, scaling that wakes up before the crowd does.

Nine surfaces — six apps and three web portals — with one coherent API. Users, partners, and experts each see their own product, but bookings and calendars stay honest in real time. Most shops would have shipped three backends and a maintenance nightmare; we got one platform we can actually evolve.

Crash games live or die on fairness and latency. Players need to trust the round, and the server has to win the math without feeling rigged. They built provable fairness and atomic cashouts — and infrastructure meant for serious concurrent load, not a demo that collapses on a busy evening.

Color prediction looks simple until thirty thousand people hit the same sixty-second round. Pool math and settlement can't leak margin or trust. Their pool-matching engine and Redis-backed bet flow meant we could scale rounds without the database catching fire — that is the product.
