Analysis

We map the flows that make or break a travel app before we build: the first thirty seconds, purchase, activation, and status. In this space the margin for error is tiny. When we started on Nimbus, the eSIM connectivity app, there was no codebase, no design, no market research, a founding team new to telecom, and a partner API with an incomplete provisioning stack, yet the expectation was world-class experience, fast onboarding, and zero activation errors. Getting that right starts with understanding the journey in detail, not with writing code. The output is a clear product and technical direction, and an architecture decided deliberately rather than discovered halfway through.

Development

We build travel and connectivity apps for iOS and Android in React Native, with the backend and integrations to support them. For Nimbus we delivered a mobile-first app from zero code to production: one-click eSIM activation, secure code-based login with no email-and-password friction, a clean plan picker for business and leisure travellers, and a full eSIM lifecycle of activation, usage, expiry and repurchase. Underneath it sits a modular backend with a scalable provider-and-plan architecture, with Stripe, chat and invoicing APIs fully integrated, built so new providers and products can be added without a rewrite.

Depending on what your app needs, our work includes booking and purchase flows, payments, email/OTP and social sign-in, activation and status handling, supplier API integration, and the customer-support and admin tooling that keeps it running. Everything is built and reviewed by senior engineers. Where AI-accelerated development speeds delivery, senior review stays on everything that touches payments and activation, because a travel app that fails at checkout or activation fails the whole trip.

Testing

A travel app is used in the worst possible conditions: a traveller who just landed, on an unfamiliar network, who needs data working in under a minute. So we test for that reality, not for the demo. Every payment and activation path is tested on real devices, across real error edge cases, because the moment that decides whether a customer trusts your app is the moment they activate. On Nimbus, end-to-end QA on real devices and real activation was central to shipping something production-ready that integrated smoothly with existing backends, in the words of the client's co-founder, "solid, production-ready software."

Release & Maintenance

We ship with staged rollout, crash and performance monitoring, and iteration on the flows that drive conversion and retention. Nimbus went from a napkin sketch to a live product with real users and the groundwork for a multi-service platform, built by a team distributed across five countries and time zones with tight feedback loops from concept to release. After launch, ongoing app support moves onto a retainer rather than ad-hoc fire-fighting, so releases, OS updates and new features are handled by a team that already knows the app.

Two delivery strategies

Delivery strategy

MVP
to production

A defined scope taken to a real, shippable app: live payments, live activation, on real devices. Best for a first release.

Delivery strategy

Continuous
development

Ongoing iteration feeding real usage data back into the roadmap. Best when live behaviour should drive what is built next.
