What we do.

DigitalJet eliminates technical debt and modernizes your Android codebase, Whether you need ongoing app maintenance or want to scale efficiently by migrating shared logic to Kotlin Multiplatform, we deliver senior architectural execution.

The Focus

We partner with companies that have an established app but struggle with legacy code, OS compatibility crashes, or the financial burden of maintaining separate Android and iOS engineering teams.

The Location

Pure nearshore delivery aligned 100% with the EU/CET time zone - meaning seamless daily collaboration without the offshore delay.

Who this is for

DigitalJet is a good fit if:

  • You already have an Android app in production that requires ongoing maintenance or a modern architectural upgrade.
  • Your app suffers from technical debt, legacy Java/XML code, or stability issues on newer Android versions.
  • You want to transition to Kotlin Multiplatform (KMP) to share core logic with iOS and reduce engineering overhead.
  • You don’t want the risk, cost, and management hassle of hiring a full-time, in-house mobile team.
  • You need predictable monthly delivery, long-term stability, and senior technical ownership.
  • You want a nearshore partner in the EU time zone that integrates seamlessly with your internal product teams.

Who this is not for

DigitalJet is not a good fit if:

  • You’re looking for the cheapest possible development or outsourcing.
  • You need a massive agency or rapid headcount scaling.
  • You want hourly freelancers for short-term, ad-hoc task execution.
  • You’re still validating an idea or building an MVP without an existing production app.

What you get.

01 ARCHITECTURE

Legacy App Modernization

We eliminate your technical debt without breaking production. This includes migrating old Java/XML to 100% Kotlin and Jetpack Compose, refactoring to Clean Architecture (MVI/MVVM), and updating obsolete third-party SDKs.

Jetpack Compose Refactoring
02 CROSS-PLATFORM STRATEGY

Kotlin Multiplatform Migration

Stop building the exact same business logic twice. We extract your data layers, network clients, and business rules into a shared KMP module, keeping your UI native while cutting engineering overhead by up to 40%.

KMP Shared Modules Code Sharing
03 STABILITY

Proactive App Care & Support

Complete operational peace of mind. We target and eliminate real-time crashes via Firebase Crashlytics, optimize performance, and keep your app fully compliant with Google Play’s changing target API level requirements.

How we help

UI Modernization (Compose)

We incrementally migrate heavy legacy XML layouts to Jetpack Compose, making your UI faster, modular, and easier to scale.

Strategic KMP Migration

We extract network layers and business rules into Kotlin Multiplatform, sharing stable code with iOS without enforcing a rewrite of your native UI.

OS Compatibility & Upkeep

We keep your app up to date with Google Play’s target API guidelines and fix regressions caused by new Android 15/16 system behaviors.

Legacy Debt Elimination

We refactor outdated Java source code into modern Kotlin, establishing clean architectural patterns (MVI/MVVM) and solid dependency injection.

Automated Release Pipelines

We fix broken CI/CD build pipelines and handle internal testing tracks and production deployments on the Google Play Console seamlessly.

Pragmatic Technical Guardrails

We act as an extension of your technical leadership, ensuring refactoring stays focused on real business value, not overengineering.

We don’t believe in high-risk, expensive rewrites. We fix code systematically.
