Clust

A multi-sided mobility platform connecting riders, drivers, and operations through mobile apps, dispatch, payments, and real-time systems.

Clust is SystoBase’s flagship reference for end-to-end product engineering in ride-sharing — rider and driver apps, dispatch, payments, wallets, notifications, and operational tooling on production infrastructure.

Challenge

A ride-sharing operation cannot run on disconnected apps, spreadsheets, and a payment tool that does not know trip state. Riders expect live tracking and reliable settlement; drivers need fair assignments and clear payouts; ops needs one view of what is happening right now. Clust needed a single platform where those three sides stayed coherent under real load — not a stack of demos glued together.

Opportunity

Own the full product stack — mobile surfaces, dispatch logic, payments, notifications, and operator workflows — so the business can change pricing, coverage, and product flows without waiting on a third-party marketplace roadmap. That ownership is the difference between renting a ride product and running one.

Approach

We mapped the ride lifecycle and payment path before scaling architecture: request → match → trip → settlement, including failure modes (expired sessions, stale locations, webhook lag). Then we shipped rider and driver apps, the domain services behind them, and admin tooling as one system — with production constraints (idempotency, retries, geo freshness) treated as product requirements, not afterthoughts. Technical readers can go deeper in the architecture and lifecycle sections below; the business story stays here.

What we built

Rider and driver Flutter apps, React operations tooling, Django services for ride state, dispatch, location, notifications, and Stripe-backed payments — with PostgreSQL/PostGIS, Redis, Celery workers, and Firebase delivery on production infrastructure. The same ride identity flows from the mobile request through dispatch and settlement so ops, riders, and drivers are never looking at different truths.

Impact

Operations can see and intervene in live trips; product can evolve dispatch and monetization without rewriting the client stack; riders and drivers share one coherent lifecycle from request through payout. The platform is inspectable — not only described — in the architecture and ride-lifecycle sections on this page.

Result

A production multi-sided mobility platform — SystoBase’s reference for product engineering where marketplace logic, real-time systems, and payments have to stay correct together.
