What is ClickNBack

ClickNBack is a cashback platform built end-to-end as a real product: a native iOS app backed by a custom REST API, both developed and maintained by a single engineer.

The backend is deployed and running in production. The iOS app is in active development.

The platform covers standard cashback flows — authentication, offer browsing, and transaction tracking — but the goal is not to demonstrate features in isolation. The goal is to show how a product behaves as a system: how the client and backend co-evolve, how data flows across layers, how failures are handled, and how the codebase sustains itself as complexity grows.

Why build this?

After 7 years building iOS applications at companies like Cabify — a ride-hailing platform serving millions of users across Spain and Latin America — I wanted a project that demonstrates full-stack ownership: not just the iOS client, but the API it talks to, the infrastructure it runs on, and the product decisions behind it.

ClickNBack is that project. It is not a demo. It is a working product, built with the same standards I apply in professional environments.
