Android Development, Accelerated with AI

Device Compatibility Tests

AI drafts test scenarios for different Android versions, screen sizes and manufacturer customizations, and the engineer checks each test before it joins the suite.

AI Assisted Code Review

AI helps our engineers spot null safety issues, coroutine misuse, memory leaks and common Android pitfalls before a senior developer reviews the code.

Performance Across Devices

AI helps engineers read profiling data on memory, CPU and battery use, so the team can find slow screens and fix them for mid range and low end devices.

Routine Compose Code

Claude Code drafts routine Kotlin code such as Jetpack Compose screens, data classes and ViewModel scaffolding, and Compose previews let the engineer check each UI change before it merges.

The whole Unico Connect team uses Claude Code daily. Our engineering leads estimate that roughly 80 percent of our production code is AI generated. Engineers are expected to understand the code AI produces, and a tech lead or senior developer reviews it before it ships.

What Our Kotlin Android Developers Build

Native Android Applications

Full-featured Android apps with Jetpack Compose or XML layouts. Material Design 3 compliance, edge-to-edge displays, and adaptive UI for phones and tablets.

Jetpack Compose UI

Modern declarative UI built with Compose. Animations, theming, and responsive layouts that take advantage of Android's latest design capabilities.

Background Processing & Sync

WorkManager for scheduled tasks, foreground services for real-time operations, and reliable data sync strategies for offline-capable applications.

Google Play Services Integration

Maps, location, in app purchases with the Google Play Billing Library, push notifications (FCM), and Sign in with Google through Credential Manager. Deep integration with the Android platform services your users expect.

Kotlin Multiplatform

Kotlin Multiplatform proofs of concept that test sharing your business logic in Kotlin between Android and iOS, while each app can keep its native UI. Flutter is our preferred stack for cross platform mobile apps.

Android App Maintenance

Ongoing support including OS compatibility updates, crash analysis, Google Play policy compliance, and feature development.

VETTING PIPELINE

How engineers earn a spot on our team

Our hiring process has three stages, from the application screen to a project deep dive with background verification, and every new engineer then serves a probation period.

4 checks
Application screen

We source engineers across India through LinkedIn, Wellfound, employee referrals and outbound headhunting. Every application is checked for stack relevance, years of experience, English and time zone overlap before it moves to a technical interview.

60 to 90 min
Live coding and scenario questions

A live coding round of 60 to 90 minutes in the primary technology of the candidate, followed by scenario based questions on practical applications of that technology.

3 checks
Project deep dive and background verification

Candidates walk us through a recent production project, covering the architecture decisions and what they would change in hindsight. A third party background verification agency then confirms prior employment, education and identity.

Probation
A probation period follows

New engineers then serve a probation period, and those who do not meet our bar do not continue with us.

Frequently Asked Questions

Rates run $25 to $50 an hour depending on seniority, and fixed scope projects have a $10,000 minimum. US specialists bill $150 to $300 per hour for comparable work. Store and backend services are billed separately by their vendors, such as the US$25 one time Google Play developer registration fee and any Firebase usage above the no cost Spark plan limits. Your cost also depends on how many screens and platform integrations the app needs and how much existing Java code has to move to Kotlin.
