WeBuildStack is a remote-first software development company in Bengaluru, India, that builds web and mobile applications and the cloud behind them. For a dedicated React Native engineer you interview first, with a 15-day risk-free trial and a tech lead reviewing every pull request: profiles within 48 hours, a start within one to two weeks, in your timezone. 15+ engineers, 100+ projects.
Mobile engineers who have pushed many builds through both store reviews, so they know the rejection reasons before they happen. React Native with Expo by default, Flutter when the design demands it, and the Fastlane or EAS pipeline so every merge produces a signed build on your testers' phones.
Keeping a long list smooth on a low-end Android phone: FlashList, memoisation and image caching.
Offline-first state: queueing writes, retrying and resolving conflicts after reconnecting.
Writing or reviewing a small native module in Swift or Kotlin for a device feature.
Walking through a recent App Store or Play rejection and how it was resolved.
The four ways to add a React Native engineer, stated fairly. The figures in our row are the ones every page on this site commits to.
| Channel | Time to start | Who reviews the code | Continuity | Trial | Management load |
|---|---|---|---|---|---|
| Marketplace freelancers (Upwork, Fiverr) | Days | Nobody unless you arrange it | One person; no replacement | Per contract | You manage everything |
| Vetted-talent networks (Toptal, Lemon.io) | Days to a week | Your lead | Replacement by the network | Usually a trial period | You manage the work |
| Dedicated-team companies (WeBuildStack and others like us) | Profiles in 48 hours; start in one to two weeks | A tech lead reviews every pull request | Replacement guarantee; no minimum term | 15-day risk-free trial | Shared: you direct the backlog, the company handles HR, quality and replacement |
| In-house hire | Months | Your lead | Highest | Probation | Everything, including recruiting |
Need the whole thing built instead? See our Mobile App Development service.
Builds the app for iOS and Android from a clean machine and fixes anything that only works on one laptop.
Ships a screen or bug fix through your EAS or Fastlane pipeline to TestFlight and Play internal testing.
Reviews crash reports and start-up time, then sends a ranked list of stability fixes.

Yes, for a dedicated React Native engineer you interview first, with a 15-day risk-free trial and a tech lead reviewing every pull request. Profiles within 48 hours, a written monthly rate with them, a replacement guarantee, no recruitment fees and no minimum term; the engineer works in your repositories, stand-ups and hours from Bengaluru, India.
Yes. Privacy labels, data-safety forms, screenshots, review notes and the replies when Apple asks for a demo account are all part of the job. Publishing is under your developer accounts, so you keep ownership of the listings.
Yes. They write Swift and Kotlin native modules when a Bluetooth device, a payment SDK or a camera feature needs it, and keep the Expo config plugin so your builds stay reproducible in CI.
Usually within 3 to 7 working days. Profiles list the apps each mobile engineer has published, and you interview before anyone is assigned.
If the engineer is not a fit in the first 15 days, which normally includes at least one signed build on your testers’ phones, you pay nothing for that period and we replace them or part ways. No minimum term.
Detox or Maestro flows run in CI on every merge, and before each release the engineer checks the build by hand on a low-end Android phone and an older iPhone, not only on the simulator. Crash reports from TestFlight and Play internal testing are triaged in the same sprint.
What arrives within 48 hours: two or three matching profiles with code samples, each engineer's availability and earliest start date, and a written monthly rate. You interview before anyone starts.
