Building an app that actually ships, actually works, and actually gets used — that's the job.
I'm a Senior Mobile App Developer with 8+ years of experience building iOS, Android, and cross-platform apps using React Native, Flutter, Swift, and Kotlin. I've shipped apps in FinTech, healthcare, e-commerce, cybersecurity, real estate, and on-demand delivery — several of which reached the App Store's top rankings in their category.
Why clients bring me in:
Most mobile projects fail for one of three reasons: the wrong tech stack was chosen for the budget, the architecture couldn't scale past MVP, or the developer disappeared mid-project. I solve for all three. I work across both native and cross-platform stacks, so instead of forcing your project into whatever framework I happen to know, I recommend the right one for your timeline, budget, and long-term maintenance needs — then I stay through launch and post-launch support.
Core expertise:
✅ Cross-Platform Development — React Native, Redux, Flutter, TypeScript, Zustand
✅ Native iOS Development — Swift, SwiftUI, UIKit, Core Data, MVVM
✅ Native Android Development — Kotlin, Java, Jetpack Compose, MVVM/MVP/MVI architecture
✅ Backend & APIs — REST APIs, GraphQL, Node.js, Firebase, Supabase
✅ AI Integration — OpenAI API and Gemini API integration for AI-powered mobile features (chatbots, smart search, content generation inside apps)
✅ Authentication & Payments — Firebase Auth, social login, Stripe and other payment gateway integrations, in-app purchases (StoreKit)
✅ Data & Offline Support — SQLite, Realm, Core Data, Cloud Firestore, offline-first architecture
✅ Maps, Location & Real-Time Features — Google Maps, MapKit, MapBox, geolocation, real-time chat and messaging, push notifications
✅ Cloud & DevOps — AWS, Google Cloud Platform, Docker, CI/CD pipelines (GitHub Actions)
✅ Deployment — End-to-end App Store and Google Play submission, review handling, and post-launch optimization
Industries I've worked in:
FinTech and payments (cross-border remittance, peer-to-peer money transfer), healthcare (health tracking, meditation/wellness apps), cybersecurity (enterprise threat intelligence and zero-trust access apps), e-commerce and marketplaces, on-demand delivery and logistics, real estate, events/media, and social/community platforms.
Selected work:
A cross-border FinTech remittance and subscription platform built for the European market (React.js, Node.js, TypeScript, microservices, MongoDB)
A peer-to-peer digital payment app for a Caribbean FinTech startup (React Native, Node.js, Express, MongoDB)
An AI-powered identity verification SDK using NFC scanning and OCR for KYC/AML compliance, built for Android and iOS (Kotlin, MLKit, NFC, Retrofit)
A VPN application with military-grade encryption, kill switch, and subscription billing (Kotlin, OpenVPN, Firebase, In-App Billing)
Two enterprise cybersecurity apps covering threat intelligence and zero-trust network access, with role-based dashboards and audit logging (Kotlin, Retrofit, Room, Firebase)
A real-time news app for a U.S. broadcast client with live video streaming and breaking-news push alerts (Kotlin, ExoPlayer, Firebase Messaging)
An IoT control app using the MQTT protocol to manage ESP32-powered hardware in real time (Swift, SwiftUI, MQTT)
A multilingual car rental app for the Saudi Arabian market with real-time vehicle tracking and payment integration (Java, REST API, Google Maps, Firebase)
How I work:
I start every project by clarifying scope and constraints before writing a single line of code — vague requirements are where budgets and timelines go to die. From there: architecture and technical planning, iterative development with regular check-ins, testing (unit tests with Jest, manual QA on real devices), and a clean handoff with documentation. I use Git/GitHub for version control on every project, so nothing lives only on my machine.
Communication:
I respond within a few hours during standard working hours and flag risks or blockers immediately rather than letting them surface at the deadline. If something in the original plan isn't going to work, I'll tell you early enough to change course — not after you've paid for a dead end.
Availability:
I'm currently available for new projects — full-time or part-time engagements, fixed-price or hourly, MVP builds through long-term maintenance contracts.
If you need a mobile app built right the first time — whether that's a new iOS/Android build, a React Native or Flutter cross-platform app, or an existing app that needs fixing, scaling, or a new feature — send me a message with a bit about your project and I'll tell you honestly whether I'm the right fit and how I'd approach it.
