Hire Android developers who can take ownership of real production work — native Kotlin applications, Jetpack Compose interfaces, API integrations, offline workflows, performance optimization, Play Store releases and legacy app modernization — as individual engineers, technical leads or a complete mobile delivery team.
Add Android engineering capacity exactly where your roadmap needs it. Our Android developers can work inside an existing product team or take responsibility for a defined mobile workstream — from a new Kotlin app to an inherited codebase that needs modernization, stabilization or faster release cycles. For fully managed delivery, see our custom mobile app development services.
Build Android applications with Kotlin, Jetpack Compose and the Android SDK for products where platform performance, device integrations, offline capability or Android-specific user experience matter, through to Play Store release.
Modernize older Android applications without turning the project into an unnecessary rewrite: Java-to-Kotlin migration, XML Views to Compose, architecture cleanup, dependency and target SDK updates, Gradle modernization and modularization.
Connect Android applications to the systems that actually run the business — REST and GraphQL APIs, OAuth / OIDC authentication, payments, CRM and ERP integrations, maps, analytics and Firebase. For broader system work we pair Android engineers with custom software development teams.
Build applications that keep working when connectivity is weak or unavailable, using Room, local caching, WorkManager, background synchronization, retry strategies, queued transactions and safe conflict handling.
Resolve crashes, ANRs, slow startup, excessive battery use and memory pressure through startup and memory profiling, rendering and network optimization, R8 tuning and production monitoring across real device types.
Keep an existing app secure, compatible and releasable as Android, Google Play policies, third-party SDKs and backend services change — OS compatibility, security patches, release automation and technical debt reduction.
Do not staff every Android requirement with the same generic profile. Match the engineer to the architecture, product stage and responsibility the work actually carries. If your roadmap spans more than one platform, you can also hire mobile app developers across the wider mobile stack. If you need the whole application designed, built and released rather than added engineering capacity, see our Android app development services.
Production ownership, architecture decisions, performance work, modernization and complex integrations, with Kotlin, Coroutines, Flow, Compose, testing strategy and release management.
Kotlin-first native Android products and modernization of Java-heavy applications, including Java-to-Kotlin migration, coroutines, Flow, sealed types and testable business logic.
Modern declarative Android UI and gradual migration from legacy XML layouts — state management, navigation, Material 3, adaptive layouts, accessibility and View interoperability.
Inherited applications that have become hard to release, difficult to test or expensive to maintain: codebase assessment, dependency upgrades, refactoring, modularization and CI/CD.
Mobile products that depend on APIs, hardware and enterprise systems — REST / GraphQL, OAuth, payments, maps, BLE, NFC, barcode scanning, camera, biometrics and IoT connectivity.
Technical ownership rather than another pair of hands: architecture, code standards, release strategy and review — or a full pod with backend, UI/UX, QA, DevOps and cloud engineers.

Share your app, current stack, required seniority, responsibilities, integrations, device requirements and preferred working-hour overlap. DreamzTech will match the requirement to relevant Android developer profiles. You review and interview the shortlisted developers before selecting who joins your team.
DreamzTech can often shortlist 2–3 relevant Android developer profiles within 48 hours once the requirement is clear. The actual start date depends on developer availability, interviews, contracting, security review, repository access and onboarding requirements.
DreamzTech Android developer engagements can start from $20 per hour or approximately $3,200 for a 160-hour monthly allocation, subject to the role and commercial agreement. Seniority, architecture responsibility, specialized device expertise, working-hour overlap, security requirements and team composition can affect pricing.
Yes. You can hire a dedicated Android developer for an ongoing monthly allocation or build a larger Android delivery team with QA, backend, design, DevOps and project leadership based on the roadmap.
Yes. DreamzTech can match Android developers with experience in Kotlin, Jetpack Compose, Coroutines, Flow, Material 3, Android Jetpack, Room, WorkManager, Hilt, Retrofit, Firebase and other modern Android technologies according to your application requirements.
Yes. Android developers can work with existing Java applications, stabilize inherited codebases and plan gradual Java-to-Kotlin modernization where the migration is justified. A full rewrite is not always necessary.
Yes. The right approach depends on the codebase. Teams can introduce Compose incrementally, keep stable existing Views where appropriate and migrate screens or design-system components in stages rather than forcing an all-at-once rewrite.
Yes. Android engineers can support build configuration, signing, internal and closed testing tracks, staged rollout, versioning and Google Play release workflows. Store-policy and account requirements remain subject to Google’s current rules.
Yes. Developers can integrate Android apps with REST, GraphQL, WebSockets, Firebase and custom APIs as well as authentication, payments, maps, CRM, ERP and cloud services. The exact experience should be matched to your backend architecture.
Yes. Common modernization work includes Java-to-Kotlin migration, Compose adoption, dependency upgrades, target SDK updates, architecture refactoring, performance improvement, test automation and CI/CD modernization.
Look beyond Kotlin syntax. A strong Android developer should understand lifecycle behavior, state management, background execution, networking, offline data, architecture, testing, performance, security and Play Store releases. For modern native apps, Kotlin and Jetpack Compose experience are especially relevant.
Hire a native Android developer when Android-specific performance, device APIs, background behavior or a substantial Android-only roadmap matters. Flutter can be a strong fit when Android and iOS share most functionality and code sharing is a major priority — in that case you can hire Flutter developers instead. The right answer depends on product requirements, not framework popularity.
Yes. A delivery team can include Android engineers, backend developers, QA engineers, UI/UX designers, DevOps or cloud engineers and a project or technical lead. The team should be sized around the roadmap rather than using a fixed package.
DreamzTech engagements can provide full source-code and IP ownership according to the signed contract. Repository access, handoff, documentation and third-party licensing should be confirmed during contracting.
Yes. Engagements can be structured with agreed overlap for U.S. working hours and U.S.-led stakeholder communication. Define the required overlap during matching so the correct developer or team is selected.
