About this gig
High-Performance Flutter Apps | Native Power & Clean Architecture
Looking for an app that scales with your business? I build industry-standard mobile applications using Flutter & Dart, backed by deep Native (Kotlin) expertise. I don't just "code", I engineer modular, future-proof solutions.
Why Work With Me?
- Native Side Expertise: Deep experience in Kotlin. I can handle complex hardware integrations and custom platform features that standard Flutter plugins can't.
- Architecture for Growth: I use Clean Architecture & MVVM. This makes your app easier to update and significantly cheaper to maintain long-term.
- Hardware & IoT Specialist: Expert in connecting apps with physical devices like Biometric Scanners (ZKTeco/Hikvision), thermal printers, and GPS tracking.
- Clean Code: Professional linting and documentation. Any developer can pick up my code later without a "total rewrite."
What I Deliver:
- Custom iOS & Android Development: One codebase, dual-platform excellence.
- Seamless Integrations: REST APIs, Firebase, and Cloud databases.
- Secure Payments: Stripe, PayPal, SSLCommerz, and more.
- UI/UX Excellence: Smooth animations and intuitive user journeys.

FAQ
Will you provide the source code?
Yes, I provide the full, well-documented source code once the order is completed. I follow clean coding standards so that any developer can easily understand the project later.
Do you handle App Store and Play Store submissions?
I offer store submission as part of my Premium package or as a Gig Extra. Please note that you must provide your own Apple/Google Developer account.
Can you integrate custom hardware or APIs?
Absolutely. I have extensive experience with REST APIs and hardware integrations like fingerprint scanners and GPS tracking. Please message me first to discuss technical specifics.
Which state management do you use?
I primarily use Provider or Riverpod, depending on the project's complexity. I ensure the architecture is modular and follows the MVVM pattern for better scalability.
What do I need to provide to start?
Ideally, a Figma/XD design and a clear feature list. If you don't have these, message me and we can discuss building a prototype or wireframe first.
My project requires custom hardware/native features. Can you handle this?
Yes. I have extensive experience in the "Native side" (Kotlin for Android). If a Flutter plugin isn't available for your specific hardware or requirement, I can write custom Platform Channels to bridge the gap.
