Build Pillar · Mobile App Development
An app nobody opens is the most expensive thing you can build.
I build React Native apps with Expo: one codebase, iOS and Android, wired into the CRM, payments, and ops that actually run your business. A sales-team app that works the lead queue from the field, a customer app that does one thing well, an internal tool that kills a manual process. Not a showcase app that sits at four installs.
What goes into a mobile app that earns its build cost.
Not a wrapper around your website. Scoped flows, a real backend, integrations into your CRM and payments, a store launch, and maintenance through every OS update.
Scoping and flows
What the app must do, who uses it, and the screens to get there. Drawn out on paper before any code, so the build solves the real job.
React Native + Expo build
One codebase, iOS and Android. Native-feel navigation, offline handling, push notifications. Expo means over-the-air updates without waiting on store review.
Backend and API
Node.js and MongoDB, or wired into your existing system. Auth, data sync, the API the app actually runs on. Built, not bolted on.
CRM and payments integration
The app reads and writes to your CRM, takes payments through Razorpay or Stripe, fires WhatsApp and push notifications. It lives inside your stack, not beside it.
App store launch
Apple Developer and Google Play setup, store listings, screenshots, review submission, and the back-and-forth with reviewers. I handle the launch, you own the accounts.
Maintenance and updates
OS updates break apps. On a retainer I keep it running through iOS and Android version changes, ship new features, and monitor crashes. Off retainer, you own the code and any developer can pick it up.
How a mobile app project actually runs.
Map the one job
What the app exists to do, who opens it, and the shortest path through it. Feature creep killed before it starts.
Screens and data
Every screen drawn, the data model defined, the API contract written. The build has a spec before a line of code.
Ship to TestFlight
React Native build, backend wired, integrations connected. You test real builds on TestFlight and Play Internal weekly, not at the end.
Store and hand off
Store submission, review, go-live. Code in your GitHub, accounts in your name, a runbook for whoever maintains it.
One operator vs. app agency vs. marketplace freelancer.
| What matters | One operator (me) | App agency | Marketplace freelancer |
|---|---|---|---|
| Cross-platform | React Native, one codebase for both | Often native, two builds, two bills | Varies, often one platform only |
| Connects to your business | Wired into CRM, payments, ops | Extra scope, extra invoice | Usually a standalone app |
| Who builds it | I do, start to finish | Junior dev, rotating team | One person, until they vanish |
| Backend included | Backend and API built together | Separate team | Often not offered |
| Store launch | Handled, including reviewer back-and-forth | Handled, slowly | Left to you |
| After launch | Maintained through OS updates on retainer | AMC contract | Gone |
Apps and the systems they run on.
Three builds across the stack: one with the mobile apps already live, two with the backend a mobile layer plugs straight into.
Three ways to bring me in.
App scope + spec
~1-2 weeks
Your idea turned into a real spec: user flows, screen list, data model, integration points, and an honest call on whether an app is even the right move. Build it with me or take the spec elsewhere.
App build sprint
6-10 weeks
A focused v1: React Native app, backend and API, core integrations, tested on real devices, submitted to both stores. One job, done well, fixed scope.
Retainer
ongoing
I keep the app alive. New features each cycle, OS-update fixes, crash monitoring, store resubmissions. Friday WhatsApp report on usage and what shipped. Pause anytime.
The real questions before building an app.
Tell me what the app needs to do.
Send me a short brief: who opens the app, the one job it does for them, and what it needs to connect to. I will reply within 24 hours with whether an app is the right move, what a v1 looks like, and a rough timeline. No sales call needed.
