Need a mobile app that is reliable, secure, and actually ships? I’m a Senior Mobile Developer with 11+ years of experience building production Android, iOS, and Flutter apps, with a strong focus on payments, POS, and e-commerce.

What I can do for you:

Build Flutter apps from scratch (Android + iOS from one codebase)
Maintain, debug, and improve existing Flutter, Android (Java), or iOS (Swift) apps
Migrate apps to Flutter (I’ve led a React-to-Flutter migration with a 30% performance improvement)
Integrate payment gateways, third-party SDKs, and hardware devices (payment terminals, barcode scanners)
Connect your app to a backend: REST APIs, Supabase, Firebase, Google Maps
Set up CI/CD (CodeMagic, Fastlane, GitHub Actions, Azure Pipelines)
Publish and manage releases on Google Play Console and App Store Connect

Why work with me:

Worked on enterprise payment apps used in real transactions, with a security-first mindset
Led dev teams and mentored junior developers, so my code is clean, reviewed, and maintainable
Full-stack background (PHP, MySQL, Supabase), so I can handle both app and API
Clear communication, honest timelines, and I flag risks early
Use of modern AI tools (Claude Code, Copilot) to deliver faster without lowering quality

Tech: Flutter/Dart, Android (Java), iOS (Swift/SwiftUI), Supabase, Firebase, REST APIs, Figma-to-code

Send me a message with your project idea and I’ll reply with a clear plan and estimate.
