His endless patience, scientific guidance, constant encouragement, constant and energetic supervision, constructive criticism, valuable advice, reading many inferior drafts and correcting them at all stages have made the completion of this project possible. Touhid Bhuiyan, Professor and Head of CSE Department for his kind help to complete our project and also to other faculty members and staff of CSE department of Daffodil International University. We would like to thank all our course fellow at Daffodil International University who participated in this discussion during the completion of the course work.
Therefore, this project was intended to build a service system, considered as "Android-based electronic product service system" which can be the ultimate solution for the purpose. This project expects to reduce a lot of workload that people don't have to go out to find a service solution.

For the back-end it will use Nodejs and for the database we will use MongoDB. Therefore, the purpose of this project is to develop an "Android-based electronic product service system" to enhance user satisfaction. The main purpose of "Android Based Electronic Product Service System" is to make a faster and smarter way to service all electrical products.
This project wanted to develop a user-friendly service system for servicing products for the consumer. The system will contain both an android application and a web application to achieve customer satisfaction. This will help us to make a good backend for our app and also for the web app.
For the second hand product our team will ensure its quality and we will provide additional 6 months service warranty for that product. This project aimed to develop a user-friendly service system for product service to the customer.

All requests will be identified, verified and forwarded by the system administrator, which will help to cut off unnecessary requests. In this way, the customer can follow his request for direct update and the local business market will not be disturbed. All orders and requests will be checked by an administrator, which will help stop irrelevant advertising.
3] In order to capture the market, we need to target the bot operating system, so we need to make two different applications or come up with a solution with applications that can run on both operating systems. We intended to provide a web service, so we have to deal with “React”, which is one of the most popular website builders. We also learn XML to design the user interface of the application. We faced many bugs and errors during this project.
We have to learn a completely new login method as well as Online payment gateways for payment method unknown to us. This project "Android-based electronic product service system" is an optimal service solution for home appliances.

Front End Design .1 Android App
- Admin Panel Login Page
They can use email and password for their login or they can use a Google account to login. If someone has forgotten their password, there is a forgot password button that will send a reset email to the email address to reset the password. Required Information (1) Name, (2) Email, (3) Password (4) Confirm password then the user must click on the "Sign Up" button.
If the user clicks that backlink, it will automatically verify the user's account and allow that user to login. After successful login or registration, the user will be redirected to the home page. With this escape, they can use any kind of online banking system like Bkash, Nagad, Rocket, etc.
Back End Design Database
We used Figma [an online UX design application] for the initial design of our app. The user experience is constantly improving as we give priority to improving user satisfaction and providing a pleasant experience while using the app in the trade.

We can say that "Android-based electronic product service system" is a mobile application as well as a web-based service system that is essential for every society. In the 21st century, while the world is developing based on the industrial revolution day by day, at that very time there is a factor that threatens this positive growth. Therefore, the harmful chemical contained in this product is released into the environment, causing damage to human blood, kidneys, and peripheral nervous systems.
In this application, when we register a supplier or workshop as a service provider, we will take all the details of their work policy at the moment. First, we want to make sure they followed all safety rules based on human, environmental and ecological balance. We will be aware, educate and monitor them to prevent this menace which reduces E-waste and contributes to a healthy environment.
To ensure our customers' security, before we collect any data, we will be informed about the data collection purpose and usage policies of a business or organization, in details opt-out email form. We will provide specific guidelines for professionals to perform their roles and how to conduct themselves when situation with professional practice. We will evaluate potential risk level and risk frequency on a scale of high, medium and low as well as update incident handling process on a regular basis to prevent security threat and meet user requirements.
10] We will implement our service center to support customer as well as brand value. Most importantly, we will create a service fee offset at checkout that will increase customer satisfaction and retain them with the app. Consider an e-commerce marketplace to sell we will use merchandise business policy that will increase business opportunity and support the sustainability of our application.
The functionality of this application is designed based on the above features so that the applications can have a positive impact on society and environment and can be sustainable for the next 10 years. This website provides an easier service solution for users and creates a unique business model for its seller. In addition, it can be the best solution for suppliers, service providers and customers, everyone's products by providing an essential service based on their need, also saves time.
