Native & cross-platform
Mobile App Development
Vrishchika Infotech develops mobile applications for Android and iOS that are shaped by a defined business requirement and a considered user experience. Each build is planned for the platform it runs on, tested on real devices, and supported once it is live.
Capabilities
What Mobile Development Includes
The work that makes up a mobile engagement, from the first platform decision through to the releases that follow launch.
Android Development
Native Android applications written in Kotlin against the Android SDK, using Jetpack components for navigation, lifecycle, background work and local storage. Builds target a current API level, with a minimum version chosen from the devices the audience actually carries. Release work is part of the job: signed builds, Android App Bundles and staged rollouts on Google Play.
iOS Development
iOS applications built in Swift, with SwiftUI or UIKit chosen according to the interface and the iOS versions the app has to support. Development happens in Xcode against Apple’s current SDKs, following the platform’s own interface conventions rather than porting an Android layout across. Code signing, provisioning and App Store submission are handled as part of the release.
Cross-Platform Development
Flutter and React Native, used where a single codebase across Android and iOS serves the requirement better than two native ones. The trade-off is settled before the decision is made: shared code costs less to maintain, native code sits closer to platform behaviour, and either route can still need a platform channel for specific features.
API Integration
Connecting an app to the systems it depends on over REST, covering authentication, pagination, error states, retries and what happens when the network drops. Responses are parsed into typed models rather than passed around as loose dictionaries, so a change on the server surfaces during development instead of in a crash report. Where an interface does not exist yet, we specify and build it alongside the app.
Firebase / Backend Integration
Firebase where a managed backend keeps a project simpler: authentication, Cloud Firestore, Cloud Storage, Cloud Messaging for transactional notifications and Crashlytics for post-release diagnostics. When the requirements outgrow that, we build a Node.js service with its own database and keep the app talking to one documented interface.
App Performance Optimization
Measurement before change: cold start time, frame rendering, memory use, network calls and battery impact, profiled on real devices as well as emulators. Typical work includes moving expensive operations off the main thread, reducing image and layout cost, caching what is safe to cache and trimming the size of the shipped binary.
Maintenance & Version Updates
Applications need attention after launch: new operating system releases, changed platform requirements, deprecated APIs and dependency security updates. We keep an app building and shipping over time, fix defects reported from production, and group enhancements into planned releases rather than scattering them across one-off patches.
Development workflow
How a Mobile Project Runs
The same four stages on every engagement. On a mobile build they cover the platform decision and requirement detail, interface and architecture planning, development tested on real devices, and the release and support that follow.
- 01
Discover
Understand requirements, business objectives, users and technical needs.
- 02
Design & Plan
Define user experience, technical architecture, milestones and implementation plan.
- 03
Develop & Test
Build using maintainable code while testing functionality, usability and performance.
- 04
Launch & Support
Deploy the finished product and provide continued maintenance and improvement when required.
Technology
The Mobile Stack
Tooling is chosen for the project rather than by habit. These are the technologies used most often on mobile work, along with the services that usually sit behind an app.
Native and cross-platform
Kotlin and Java with the Android SDK and Jetpack on Android, Swift and SwiftUI on iOS, and Flutter or React Native when one shared codebase is the better fit for the requirement.
- Kotlin
- Java
- Android SDK
- Jetpack
- Swift
- SwiftUI
- Flutter
- React Native
Backend and integration
Most applications need something behind them. We build REST interfaces on Node.js and use Firebase for authentication, data and file storage where a managed backend keeps the project simpler to run.
- Node.js
- REST APIs
- Firebase
