Kotlin Multiplatform (KMP) & Native Mobile
Shared Kotlin Multiplatform domain logic paired with native SwiftUI (iOS) and Jetpack Compose (Android) interfaces, offline sync, and store release prep.
- Engineering teams maintaining duplicate iOS and Android business logic with drifting bug fixes
- Field operations, logistics, and fintech products that must keep working in patchy mobile coverage
- Founders launching a mobile product who want native iOS/Android feel without funding two full teams
Technical bottlenecks we resolve
Concrete operational and architectural issues we eliminate for engineering teams.
iOS and Android teams implementing the same API, caching, and validation rules twice
Share 70–85% of non-UI domain logic in Kotlin Multiplatform while keeping native SwiftUI and Compose screens.
App crashes or lost form data when field staff lose 4G/5G signal
Encrypted local SQLDelight storage with deterministic background sync queues when connectivity returns.
Manual, error-prone mobile builds slowing down QA feedback
Automated Fastlane / GitHub Actions pipelines publishing signed builds to TestFlight and Google Play Internal Testing.
Kotlin Multiplatform Shared Domain Core with Native SwiftUI & Jetpack Compose UI
Native UI Layers
Platform-native rendering, gestures, and accessibility support.
Shared State Engine
Unidirectional state management and shared business rules.
Encrypted Offline Store
Local persistence with queued background delta reconciliation.
Typed Networking
TLS networking with automated token refresh and retry backoff.
Native UI Responsiveness
Platform-native SwiftUI and Jetpack Compose views without WebView wrappers.
Offline-Capable Workflows
Local state persistence lets field and clinical users queue actions during spotty connectivity.
Hardware-Backed Auth
Face ID, Touch ID, and Android BiometricPrompt wired to platform-encrypted credential stores.
Store Policy Readiness
Pre-submission compliance checks against Apple HIG and Google Play privacy/permission guidelines.
Start with one bounded workflow before any ongoing commitment
Clear deliverables, client prerequisites, exclusions, and acceptance criteria so expectations match on both sides.
- Clean KMP + iOS/Android repository structure in your Git account
- Authentication plus one core end-to-end user workflow on iOS and Android
- Local SQLDelight offline cache wired to your staging API
- CI build pipeline publishing to TestFlight and Google Play Internal Testing
Shared KMP module + one end-to-end native screen flow (e.g., auth + offline-cached core workflow) on iOS & Android.
Staging REST/GraphQL endpoints (or mock spec), brand assets, and Apple Developer / Google Play Console test access.
Apple/Google review turnaround times, hardware peripheral SDK licensing, and full multi-screen store launch.
Signed iOS TestFlight and Android Internal Track builds passing agreed functional scenarios on physical devices. Backed by a 10-business-day defect remediation window. 100% of IP assigns upon pilot invoice settlement.
Offline-Capable Micro-Lending & Field Onboarding Platform
Completed Client Engagement (Client anonymized under mutual NDA)
Client Problem
Field credit officers onboarding rural borrowers faced frequent 3G dropouts that wiped multi-step KYC forms, while manual back-office underwriting checks took 2–3 days per application.
What We Delivered
- Offline-capable KMP field agent app storing encrypted KYC drafts locally until sync
- Idempotent Spring Boot credit-scoring and disbursement orchestration APIs
- Role-based back-office review queue with immutable PostgreSQL audit logs
- Automated Testcontainers integration suite covering payment webhook retries
Measured Results & Basis
Measured via p95 Spring Boot API response telemetry across rule-engine and credit-bureau lookup calls.
Verified via unique idempotency-key constraints and daily ledger reconciliation audits post-launch.
Common technical & commercial questions
Key implementation, security, and pilot sprint answers for your engineering team.
Why Kotlin Multiplatform (KMP) instead of React Native or Flutter?↓
KMP compiles directly to native JVM bytecode on Android and native Objective-C/Swift frameworks on iOS with no bridge overhead, letting your team keep 100% native SwiftUI and Compose UI. Where a unified UI toolkit fits better, we also deliver in Flutter.
Do you guarantee App Store and Google Play approval?↓
Final store approval is always controlled by Apple and Google reviewers, so no honest agency can guarantee instant approval. We prepare releases against Apple HIG and Play Store policies and remediate any engineering-related review feedback built within agreed scope.
