Flutter Developer | Complete App Development from Scratch to Production -- 2

I am a Flutter application developer with hands-on experience building a complete restaurant ordering and management platform.

I developed the application from scratch to production deployment, including requirement planning, UI design, project architecture, development, API integration, testing, debugging, optimization and Android release management.

My end-to-end responsibilities included:

Planning the complete application workflow and technical structure
Developing the Flutter Android application from scratch
Creating responsive and user-friendly interfaces
Integrating REST APIs with the mobile application
Implementing QR-based restaurant ordering
Building dine-in, takeaway and manual-order workflows
Managing order, payment and kitchen-preparation statuses
Integrating Bluetooth thermal printers for 58 mm and 80 mm invoices
Implementing staff roles, permissions, wallets and incentives
Developing restaurant analytics and sales dashboards
Adding local storage and API-response caching
Reducing duplicate and unnecessary API calls
Fixing bugs and improving application performance
Managing development, staging and production environments
Preparing release builds, APKs and Android App Bundles
Handling Android permissions and Play Console requirements
Deploying the application and supporting it in production
Monitoring production issues and releasing updates

I understand the complete software-development lifecycle—from converting a business idea into technical requirements to building, testing, deploying and maintaining a live production application.
