Mobile Engineering
Mobile engineering for products that handle real money, real data, and real compliance.
We build native and cross-platform mobile applications for companies where failure is not a soft landing. Our teams have shipped apps that process payments across 14 European markets, manage loyalty programs for 500K+ monthly active users, and pass PSD2 Strong Customer Authentication audits on the first attempt.
When companies come to us
You have an existing mobile product that needs architectural maturity — performance issues at scale, technical debt from rapid early development, or compliance gaps that block expansion into regulated markets.
You're building a new mobile product in a domain where security, compliance, or multi-market deployment complexity exceeds what a generalist team can handle. Fintech apps that touch PSD2/SCA. Retail platforms integrating with point-of-sale hardware. Healthcare applications subject to data residency requirements.
Your internal team is strong on backend or web, but you need senior mobile architects who have already solved the specific problems you're facing — not engineers who will learn on your timeline.
Engagement model
We offer three models depending on your stage and constraints:
- Fixed-scope builds: defined deliverable, milestone-based billing, 8–16 week timelines typical for MVP-to-v1 products
- Embedded teams: 2–4 senior engineers integrated into your workflow on 3–12 month retainers, operating as an extension of your internal team
- Architecture sprints: 2–4 week intensive engagements focused on solving a specific technical problem — migration, performance, compliance remediation
Technical competencies
Our mobile practice is built on depth, not breadth. We do not chase every framework — we go deep on the platforms that matter for production-grade applications.
- iOS: Swift, SwiftUI, UIKit, Combine, Core Data, CloudKit, WidgetKit
- Android: Kotlin, Jetpack Compose, Coroutines, Room, WorkManager
- Cross-platform: React Native with native module bridges for performance-critical paths
- Integrations: payment SDKs (Stripe, Adyen), biometric authentication, NFC, Bluetooth LE, hardware peripherals (fuel pumps, POS terminals)
- Compliance: PSD2/SCA implementation, GDPR data handling, PCI DSS for card-present transactions, App Store / Play Store regulatory review preparation
- CI/CD: Fastlane, Bitrise, GitHub Actions, automated screenshot testing, staged rollouts
What you get
Every engagement produces working, production-deployed software with complete handoff documentation:
- Production-ready application deployed to App Store and/or Google Play
- Architecture decision records (ADRs) for every non-trivial technical choice
- Automated test suite (unit, integration, UI) with CI/CD pipeline configuration
- Runbook for ongoing maintenance, monitoring, and release management
- Knowledge transfer sessions with your internal team
Sample engagement
A Fortune 500 European convenience retailer needed to rebuild their consumer-facing loyalty and payments mobile platform across 8 countries. The existing app had accumulated four years of technical debt, could not pass PSD2 Strong Customer Authentication requirements, and was integrating with 85+ fuel pump communication protocols across different hardware vendors.
We deployed a team of 4 senior mobile engineers for 14 months. The rebuilt platform launched on time, achieved PSD2 SCA certification in all target markets, and scaled to 500K+ monthly active users within the first year. The new architecture reduced average app crash rate by 94% and cut feature development cycle time by 60%.
