What do you need help with?

A new mobile product needs engineering expertise

Turn product requirements into a mobile application. Engineers assess platform constraints and implement core workflows, with technical choices grounded in device requirements and the expected maintenance workload.

Separate apps are slowing feature delivery

Assess where shared code can reduce duplicate development across mobile platforms. Cross-platform engineers evaluate existing dependencies and implement shared features while preserving native behavior where the product requires it.

Mobile workflows need backend or device access

Connect an app to business systems or device capabilities. Mobile engineers implement authenticated API access and handle interrupted connectivity, including data synchronization when users return online.

An existing app needs ongoing engineering support

Add engineering capacity for an app already in production. Specialists investigate crashes and maintain compatibility with operating system updates, while supporting store submissions and planned feature changes.

Native iOS and Android development

Build platform-specific applications or extend an existing codebase with native mobile developers. They translate product requirements into tested screens and device behavior, including accessibility requirements.

iOS developers: Implement Swift applications using SwiftUI or UIKit, connect Apple frameworks and maintain compatibility with supported iOS versions.
Android developers: Build Kotlin applications using Jetpack Compose or existing Views, manage background processing and investigate device-specific defects.

Native engineers can also review architecture and identify constraints before substantial feature development begins.

Cross-platform app development

Flutter developers and React Native engineers build shared mobile applications while retaining native code where device APIs or performance requirements demand it. Bring them in for a new application or a focused assessment of whether an existing product can support shared development.

Work can cover Dart or TypeScript implementation, reusable interface components, native module integration and automated tests. Engineers assess plugin maintenance and platform differences before recommending code sharing, so the decision accounts for ongoing support as well as initial development.

API and device integration

Connect mobile workflows to backend services and device capabilities. Mobile integration engineers implement REST or GraphQL clients and coordinate API contracts with backend developers.

Identity and data: Integrate OAuth 2.0 or OpenID Connect, protect credentials in platform storage and implement offline synchronization with explicit conflict handling.
Device features: Add push notifications and deep links, or connect camera and location workflows with appropriate permission handling.

Integration testing covers expired sessions and interrupted requests before changes reach production.

App maintenance and release support

Keep an existing application compatible with operating system changes and store requirements. Mobile maintenance engineers investigate production defects using Firebase Crashlytics or Sentry, then profile affected workflows to isolate memory or responsiveness issues.

Release engineers configure mobile CI/CD with GitHub Actions or Bitrise and maintain signing credentials. They support App Store Connect and Google Play submissions, including staged rollouts and release checks. Ongoing support can include dependency upgrades and regression testing across the agreed device coverage.

Selected work

Enterprise digital platform delivery for a European Qualified Trust Service Provider

A leading European trust service provider required senior technical and delivery capacity to manage the expansion of its national digital identity platform under strict regulatory deadlines. We deployed specialized consultants to support requirements scoping, AWS cloud architecture, and end-to-end integration workflows. The project was delivered on schedule, successfully rolling out compliant onboarding and biometric verification at national scale.
