Mobile Systems.
Native-grade apps that hold 60fps under load.
Premium native experiences designed for the next generation of handheld tech.
Mobile Systems is where we build the apps people actually keep on their home screen. Most of what we ship runs on React Native with the New Architecture (Fabric and TurboModules), reaching for SwiftUI or Kotlin when a screen needs real platform fidelity or a native sensor pipeline. The shared rule across both paths is the same: the app should feel like it belongs to the phone, not like a website wearing a wrapper.
We treat a mobile app as a constrained system, not a smaller web page. Memory is finite, the network is hostile, batteries drain, and a single dropped frame is visible to the human eye. So we design for the worst case first — cold start on a mid-tier Android device, offline writes that have to reconcile later, a list with ten thousand rows — and let the best case take care of itself.
This service is for founders and product leaders who have outgrown a prototype and need an app that holds up in the store: predictable performance, real crash-free numbers, and a release process that does not require a heroic effort every two weeks.
Production App Binaries
Signed, store-ready iOS and Android builds on React Native New Architecture, with SwiftUI or Kotlin modules wherever a screen needs native fidelity.
Offline-First Data Layer
Local-first storage with background sync, optimistic writes, and conflict resolution so the app stays usable on a dead subway or a bad hotel network.
Release Pipeline
EAS or Fastlane lanes for automated builds, code signing, TestFlight and Play internal-track distribution, plus over-the-air update channels for JS-safe fixes.
Performance Budget & Instrumentation
Enforced startup, frame-rate, and bundle-size budgets wired to Sentry and Firebase Performance, with crash-free session tracking from day one.
Design System for Touch
A typed component library with gesture, haptics, and motion primitives that respect platform conventions on each OS.
Handover Engineering Docs
Architecture notes, module ownership, signing-key custody, and a runbook your team can ship the next release from without us.
Founders and product leaders shipping a real consumer or B2B app that needs native-grade performance, dependable crash-free numbers, and a release process that runs on rails instead of heroics — not a web app in a wrapper.
React Native or fully native? How do you decide?
Default is React Native on the New Architecture because it gives one codebase, fast iteration, and OTA fixes for JS-layer bugs. We drop to SwiftUI or Kotlin per screen when something needs real platform fidelity — complex camera or sensor pipelines, deep widget and Live Activity support, or animation that has to be perfect. It is a per-feature decision, not an all-or-nothing one.
How do you keep the app from getting slower release after release?
Cold start, frame time, bundle size, and memory each carry a hard number, and a build that regresses any of them does not merge. In production we watch crash-free sessions and slow-frame rate in Sentry and Firebase Performance, so a degradation surfaces as a metric on a dashboard well before it surfaces as a one-star review.
Can our team take over the codebase after launch?
Yes — that is the intended end state. You get typed, documented code, signing-key custody, CI lanes anyone can run, and a release runbook. We can stay on for a retainer if you want, but the handover is built so you are not dependent on us to ship version two.
