Cross-Platform App Development
Full-cycle React Native apps in TypeScript — architecture, UI, native modules, store submission — sharing one codebase across iOS and Android.
JavaScript-powered native apps — React Native engineers who turn one codebase into two five-star store listings.
Devlex Infotech's React Native developers build native-feeling iOS and Android apps from a shared TypeScript codebase, letting your web and mobile teams speak the same language. We work with the modern React Native stack — the New Architecture, Expo EAS, Reanimated 3, and TanStack Query — to deliver apps that start fast, animate at 60fps, and share up to 90% of code across platforms.
Founded in 2020, we have delivered 25+ projects for 10+ clients in 5+ countries, with React Native powering many of our fintech, marketplace, and on-demand delivery builds. Hire a single senior engineer to accelerate your roadmap or a full cross-functional pod with QA and DevOps — backed by our 95% client retention rate and 24/7 production support.
Full-cycle React Native apps in TypeScript — architecture, UI, native modules, store submission — sharing one codebase across iOS and Android.

The frameworks, platforms, and tools our react native developers work with every day.
“Devlex rebuilt our patient scheduling platform from a legacy PHP system into a HIPAA-compliant React and Node.js application. No-show rates dropped 27% within three months of launch, and their team caught compliance gaps our own auditors had missed.”
“They delivered our Flutter app for iOS and Android in 14 weeks, exactly on the quoted budget. App Store rating sits at 4.8 and the weekly sprint demos meant there was never a single surprise.”
“We hired a dedicated team of five from Devlex to build our property management portal, and eighteen months later they still feel like our own employees. Releases ship every two weeks and platform uptime has held at 99.95%.”

Rates begin at $20/hour, with dedicated full-time engineers from $2,600/month (160 hrs/mo). One React Native team replaces separate iOS and Android teams, so total project cost typically drops by a third.
Within 24-48 hours. We maintain an in-house bench, so there is no sourcing lag — you review profiles the same day, interview within 24 hours, and onboarding starts immediately after sign-off.
Always. The NDA is signed before any product discussion, and every engagement contract assigns full intellectual property and source code ownership to you from day one.
Yes — we guarantee at least 4 hours of daily overlap with North American and European schedules, run async updates for the rest, and provide 24/7 support once your app is live.
If a developer is not meeting the bar, we swap in a replacement free of charge — typically within 5 business days — and manage the knowledge transfer so your sprint cadence never breaks.
