Mobile App Development | Cross-Platform iOS & Android Solutions
I build high-performance, native-feeling mobile applications for both Apple iOS and Google Android from a single React Native and Expo codebase. This methodology dramatically slashes your initial development costs and simplifies long-term maintenance, as updates are published to both app stores simultaneously. Whether you need a standalone mobile application or a companion app that talks to your existing web platform backend, I handle everything from database schema integration and native device APIs to App Store optimization and publishing.
Geographic Alignment & Remote Execution
My mobile development services are designed to solve the challenges of diverse device ecosystems and network constraints. In West Africa (Nigeria, Ghana), I optimize applications to be lightweight (smaller download sizes) and design offline-first databases so apps work reliably when offline. I integrate SMS verification APIs (like Termii) and localized payment frameworks. For global businesses, I provide smooth integrations with FCM, Apple APNs, Stripe Terminal, and modern authentication protocols to ensure compliance with GDPR and CCPA guidelines.

Process Roadmap
Step 1
Feature Mapping & Flows
We specify user journeys, screen flows, offline-handling requirements, and backend API contract designs for both operating systems.
Step 2
Mobile-First UI Design
I design interactive, high-fidelity mobile layouts in Figma, optimizing for comfortable touch targets, standard gestures, and brand identity.
Step 3
Development & Expo Testing
Writing code in TypeScript. You receive access to live development builds via Expo Go, allowing you to test features on a real phone from day one.
Step 4
Beta Testing & TestFlight
We publish beta releases via Apple TestFlight and Google Play Internal testing to gather feedback from real-world user devices.
Step 5
App Store Submission
I compile the production bundles using Expo Application Services (EAS), set up the store listing assets, and guide the app through approval.

A global fintech platform backend and multi-app frontend suite unifying accounts, multi-currency FX, card issuance, blockchain settlement, and compliance, alongside two embedded sub-products — an offline/NFC point-of-sale system and an escrow-based safe-transaction service.
Pillar FAQs
Why do you use React Native and Expo instead of native Swift or Kotlin?
React Native compiles to native components, giving you the identical speed, look, and feel of Swift/Kotlin. By using it alongside Expo, we write a single codebase that deploys to both iOS and Android. This reduces development time and ongoing maintenance budgets by up to 50% without sacrificing user experience.
How do your mobile apps handle unstable internet connections?
I design apps with an offline-first architecture. By implementing local storage engines like SQLite, AsyncStorage, or WatermelonDB, the app caches user interactions locally and securely. Once the internet connection is restored, it background-syncs the cached data with your primary server.
Do you handle the entire app store approval process?
Yes. Publishing to the App Store and Google Play can be complex due to strict privacy policies and interface requirements. I handle metadata optimization, screenshot generation, privacy policy compliance, app store review notes, and submission troubleshooting until the app is live.
Can the mobile app connect to my existing website or database?
Absolutely. If you already have a web dashboard, CRM, or backend API (Node.js, Laravel, Django, etc.), I build the mobile app to communicate with that same backend. This ensures user profiles, data records, and administrative settings stay perfectly synchronized across all screens.
What is your stack for user authentication on mobile?
I implement secure OAuth flows including "Sign in with Apple" and "Sign in with Google," native biometrics (Face ID/Touch ID), and phone number verification (OTP) via SMS gateways to maximize login security and minimize friction.
