What we do

Product engineering, end-to-end.

From the first sketch to the App Store — design partnership, mobile, backend and ops, delivered as one tight package.

Mobile, native-grade

iOS and Android, written in React Native or Flutter where it fits — and native when it doesn't. Built for App Store review on day one and instrumented from launch.

React NativeFlutterSwiftKotlin

Full-stack, end-to-end

APIs, auth, payments, dashboards. A .NET or Node backend that runs in production with monitoring, logs and a deploy pipeline your team can own.

.NET 8NodePostgreSQLAzure

From idea to shipped

Specs, design partnership, build, store submission. One team, one Slack channel, one timeline — not a relay of agencies and contractors.

Shipped, not shelved.

A selection of apps Nyxtron has built and ships. Each one is in production today — mockups shown, tap through to the live stores.

Frequently asked

Questions, answered.

Most projects run 6–14 weeks. We start with a discovery sprint to lock scope, then move into 2-week build cycles with a demo and a deployed build at the end of each. Post-launch retainers are available for continued iteration.
Yes — UX flows, prototypes and ship-ready interface work are part of the standard package. For deeper brand or motion systems we partner with a curated network of senior designers, but you'll always have one point of contact at Nyxtron.
React Native, Flutter or native Swift/Kotlin on mobile. .NET 8 or Node on the backend. PostgreSQL, Azure, Expo. We pick the stack in week one based on what the product actually needs — never before.
Absolutely. We drop into existing repos, review code and ship pull requests like any senior engineer would. If your team is stuck on a hard mobile or full-stack problem, that's exactly where we're useful.
We're remote-first and work across time zones with clients globally. All communication runs through a shared Slack or Teams channel, with weekly written progress updates and a live demo at the end of every sprint.
