Swift/Kotlin Mobile App Update & Support

Budget: 3500 EUR Deadline: 30 days

Hello.
I am an iOS/Android developer with 10+ years of experience.
I work for an hourly rate of $30/hour.
I have experience with smartwatches, BT, NFC, and other sensors. I am interested in learning the technical specifications regarding the task that needs to be implemented.
Feel free to write, I would be happy to collaborate.
P.S. Something doesn't add up. You mention a mobile application in Swift/Kotlin, but then you talk about Flutter. Do we have a native application or is it still a Flutter cross-platform one? Thank you for your attention.

Budget: 3500 EUR Deadline: 21 days

Hello, I have experience in writing applications for connecting and working with BT headphones. I have experience working with both native applications and Flutter; I have been writing in Flutter for almost 5 years. I would be happy to help with your application.

Hello, Daria.
My last project, a fitness tracker for Android OS, was written using the Flutter framework and uses a BLE sensor to monitor the user's physical activity.
To connect the Bluetooth sensor, I used the flutter_blue_plus plugin.
The application runs a service that receives data from the sensor (accelerometer and gyroscope readings) and does not allow the application to be closed when it is not active.
I started the Android service through the platform channel, using MethodChannel.
The code for the application that starts the service is written in Kotlin. Flexible notification settings were important for my project, so I did not use third-party plugins.
My experience is well-suited to solve your task, and I would be happy to take on the project.
I am ready for long-term cooperation.
I will answer your questions in private messages or via video call.

Hello,

I'm interested in your mobile app development project on FreelanceHunter. With extensive experience in Bluetooth communication for iOS and Android using Swift and Kotlin, I am well-equipped to handle firmware uploads, downloads, and AWS integration for your smartwatch app. I have successfully worked on apps that maintain Bluetooth communication in the background efficiently.

Additionally, I have experience incorporating Flutter modules to streamline the development of new UI features, which will simplify future updates across platforms.

The initial task of 120 hours aligns with my capability to deliver quality work on time. I'm also eager to provide ongoing support and feature enhancements.

Thank you for considering my proposal. I look forward to contributing to your project.

Best regards,

Jakub Expand

Hello, Daria.
I read your requirement carefully and understood all.
As a senior mobile app developer with 4 years of experience in Swift/Kotlin on both of Android and iOS, I'm very confident that I can complete this project perfectly and deliver on time.
I have strong background in file management application development to watch.
I have built the similar project with yours before.
The app name is wearFile, as you know, it is a file management app that allows users to upload, view, and manage files directly from their smartphones and sync them with compatible smartwatches
And in this development, I have integrated this app with AWS.
So I think, my previous work experience is very suitable for your project.
Based on my similar experience in development of your project, I'm very confident again.
I'd like to discuss with you.
Thank you. Expand

Experience in developing Android and iOS applications for over 8 years. I am implementing this project.

Hi Daria,

I have extensive experience in mobile app development, particularly with Kotlin. Based on my knowledge and experience, I believe Kotlin is a superior choice for implementing Bluetooth (BT) communication compared to iOS. Additionally, I find that Xamarin also performs well in this area, as it compiles to native code and provides near-native performance for mobile apps. This allows for seamless access to all native APIs.

My Qualifications in Bluetooth Communication:
Bluetooth Integration: I have developed and integrated Bluetooth-enabled applications that facilitate communication between mobile devices and peripherals, ensuring optimal performance even while running in the background.
File Transfer Projects: I’ve worked on projects that involve transferring files between mobile devices and wearable technology, focusing on reliability and enhancing user experience.
Experience with AWS Services:
AWS SDK Implementation: I have implemented AWS SDKs for file uploads and management, ensuring efficient data handling and robust security protocols.
Cross-Platform Development:
I have experience using Flutter for UI design, which enables rapid development of new features while providing a consistent user experience across platforms.
I am also open to discussing long-term support and future updates, including the addition of new features and adjustments to the UI as needed.

I look forward to the opportunity to work on this project and contribute to its success. Please feel free to reach out if you have any questions or require further information.
