What We Build

Full-spectrum mobile development

From product concept to App Store submission — every phase of your mobile product handled by specialists.

React Native Apps

Cross-platform iOS and Android apps from a single TypeScript codebase — with native performance and access to device APIs.

Flutter Apps

Google's UI toolkit for pixel-perfect, high-performance apps across iOS, Android, web, and desktop from a single Dart codebase.

FlutterDartMulti-platform

Native iOS (Swift)

Pure SwiftUI and UIKit development for applications that demand maximum iOS performance and the latest platform capabilities.

SwiftUIUIKitCoreData

Native Android (Kotlin)

Jetpack Compose and Kotlin for Android apps that leverage the full depth of the Android platform.

Every phase of your mobile product covered

From concept to App Store — a complete mobile delivery service.

Mobile Product Strategy

Mobile Product Strategy

We map your target user, define the MVP feature set, and choose the right technology (React Native, Flutter, or native) based on your specific requirements — not on what is currently fashionable.

Platform Recommendation

Cross-platform vs native decision framework based on your user base and feature requirements.

MVP Scoping

Define the minimum viable product that validates your hypothesis without over-engineering.

App Store Strategy

Keyword research, ASO planning, and monetisation model definition.

Technical Feasibility

Device API requirements, offline complexity, and backend dependency mapping.

Why CodeXCrew

What makes us different

01

Architecture-first thinking

We design the system before writing the code. Every project starts with a documented architecture review — so you never inherit hidden technical debt from short-sighted early decisions.

02

No surprises, no overruns

Fixed-scope projects come with firm estimates. Dedicated-team engagements get weekly burn reports. You always know exactly where your project stands and what it's costing.

03

Senior engineers only

We don't staff projects with juniors learning on your budget. Every engineer assigned to your project has at least 5 years of production experience in the relevant stack.

04

You own everything

Full IP ownership, source code, documentation, and infrastructure access on delivery. No vendor lock-in, no licensing fees, no dependency on us to keep your product running.

05

Design-dev in one team

Designers and engineers work together from day one — not sequentially. This eliminates the classic handoff gap where beautiful designs become impossible to build.

06

Remote-first, timezone-aligned

Our team spans multiple time zones but we align to yours. You'll have real overlap for live collaboration, not just asynchronous updates and morning surprises.
