About this gig
DO NOT HIRE A FREELANCER WHO JUST WRITES CODE. HIRE A PARTNER.
Most mobile apps fail because they crash under load or get rejected by the App Store due to fragile code architecture. If you are a founder or business owner, you need clean, scalable native apps.
I engineer production-grade iOS and Android mobile applications designed for user retention, security, and technical longevity.
TECHNICAL STACK & SPECIALIZATIONS
- Native iOS: Swift, SwiftUI, CoreData, Xcode
- Native Android: Kotlin, Jetpack Compose, Room
- Cross-Platform: Flutter, React Native
- AI Integrations: OpenAI API, Gemini, Claude, Chatbots
- Backend & Infrastructure: Firebase, Supabase, REST APIs
PRODUCTION PROCESS
- Blueprinting: We map out user flows and database logic.
- UI/UX: Layouts aligned with Apple & Google design guidelines.
- Clean Coding: Modular architecture (MVVM/Clean Architecture).
- Rigorous QA: Device testing and edge-case validation.
- App Store Deployment: Complete handholding through store submission.
️ THE ENTERPRISE GUARANTEE
- 100% IP Transfer & full source code ownership.
Production Stability: Post-deployment bug-patch support.

I help businesses convert modern web design and workflow automation into measurable revenue. Based in the UK, I work as a digital systems architect for brands, enterprise companies, and fast-growing B2B operations looking for high-tier digital solutions.
Too many platforms look great but fail to solve operational problems. I bridge that gap by combining premium frontend engineering (WordPress, Webflow, Framer, Wix Studio) with powerful backend automation (n8n, Make, Zapier, AI Agents).
FAQ
Will I own the source code and intellectual property?
Yes, absolutely. Upon final project delivery and milestone completion, full ownership of the source code and all intellectual property rights transfers entirely to you. You will have full access to the repositories.
Do you develop native apps or cross-platform apps?
I build both depending on your budget and goals. I specialize in native apps via Kotlin (Android) and Swift (iOS) for maximum performance, as well as cross-platform apps using Flutter for multi-platform efficiency.
How do you ensure the mobile app passes App Store reviews?
I engineer all applications in strict compliance with Apple’s Human Interface Guidelines and Google Play's Developer Policies. I handle the configuration and guide you directly through the store submission process.
Can you integrate advanced AI capabilities into the app?
Yes. I regularly implement advanced AI integrations, including OpenAI API, Gemini, and Claude services. This covers everything from intelligent chatbots and semantic search to automated data processing tools.
