Can you start from a prototype?

Yes. We evaluate what to keep, what needs production engineering, and what the first credible release requires.

Do you handle design as well as engineering?

Yes. The service covers the product as a whole, including the user experience, interface decisions, architecture, implementation, and release readiness.

Have you shipped a mobile app?

Yes. Close Circle, our own iOS app, is built with Expo and React Native. It is in TestFlight and launching soon, and its support and legal pages are on this site.

Web and mobile apps

Web, iOS, and Android, shipped as one product.

Responsive web apps, native mobile apps, and the backend they share. Design, engineering, testing, release, and the first months after.

Good product engineering connects the interface, the architecture, the operations, and the roadmap. We work across those boundaries so the product feels coherent to users on every screen and stays workable for whoever maintains it next.

You might be here because.

Start from the constraint you have, not from a solution somebody already picked.

A web product needs a companion mobile app, or the reverse.
A consumer flow is losing users to friction or instability.
A prototype needs production architecture and operational readiness.
Two apps drifted apart and now need one backend and one design.
A release has to pass App Store and Play Store review.
A business system has outgrown manual work and disconnected tools.

What changes

One product, every screen.

One backend, one design, every screen. The phone and the browser hold labelled placeholders until real screenshots exist.

What we deliver.

What an engagement can include. Scope is agreed in writing before work starts.

Product definition and technical planning
User flows and interface design
Responsive web applications
iOS and Android applications
Backend services and integrations
Testing and release pipelines
App Store and Play Store release
Post-launch iteration

Ways to engage.

Four shapes the work can take. Most engagements start small and grow into ownership.

Product definition

Turn an idea or business need into a focused plan and technical approach.

App build

Design, engineer, test, and release a web or mobile product.

Focused feature team

Own a meaningful product area inside an existing roadmap.

Launch and iteration

Support the release, learn from real use, keep improving.

How it runs.

Recorded like a drawing's revisions: what changed, and who signed it.

A
Clarify
Identify the user, the problem, the constraints, and the smallest valuable release.
B
Shape
Resolve the experience, the architecture, the integrations, and the delivery plan.
C
Build
Deliver in tested slices with regular product decisions and visible progress.
D
Operate
Release safely, observe real behaviour, and keep the roadmap moving.

Questions

Before we start.

Practical answers about this kind of engagement.

Ask something else

Yes. The product model changes, but both need clear workflows, dependable engineering, and deliberate operating decisions.
