Django and Django REST Framework Signals: Custom Signals, Model Signals

https://github.com/mansha99/django-custom-and-model-signals
This project comprehensively explores the power and flexibility of signals within the Django and Django REST Framework. As the lead developer, I was tasked with creating custom signals and using them to enforce business rules, a critical aspect of any modern web application.

The project was built using Python and Django. Django's built-in signals, a type of messaging system, were a key focus of this project, and the Django REST Framework was also utilized. I created custom signals within this framework, a feature allowing developers to add or alter functionality without modifying the framework itself.

Using signals to enforce business rules was a significant part of the project. It involved setting up certain conditions or "rules" that the application must follow, which were then implemented using signals. This approach ensures consistency and reliability within the application.

The project's repository is publicly available on GitHub through the link above, and an article detailing this project is available at https://medium.com/@mansha99/django-drf-signals-custom-signals-model-signals-enforcing-business-rules-729fc2e22c7c.

The project was built using Python and Django, and the Django REST Framework was also utilized, providing the foundation for the project.

A significant part of the project was creating and managing a virtual environment. This isolated environment allows packages to be installed for a specific project without interfering with other projects or the system's Python interpreter. It's a crucial aspect of Python development, ensuring each project has dependencies that do not disrupt others.

Another key aspect was the management of environment variables. These dynamic-named values can affect how running processes behave on a computer. They were used in this project to store and protect secret keys, a critical security measure for any web application.

A significant part of the project was the implementation of CRUD operations with validation, a fundamental aspect of any HTTP REST API, ensuring that data can be appropriately managed and manipulated. The project also involved the implementation of custom search functionality and pagination within the Django REST Framework. These features enhance the user experience, making finding specific data and navigating large amounts of information easier. Finally, sorting was implemented, allowing data to be ordered in a way that makes sense for the user. This is particularly useful in large datasets, where finding specific information can be challenging.

The project's repository is publicly available on GitHub through the link above, and an article detailing this project is available at https://medium.com/@mansha99/drf-modelviewset-crud-with-sorting-search-and-pagination-823ca756a314.

Django REST Framework: Implementing JWT and Custom User Roles

https://github.com/mansha99/django-drf-jwt

My responsibilities included creating a custom user model for mobile-based authentication, implementing JSON Web Tokens (JWT) for secure authentication, and protecting web paths using JWT authentication.

The project was built using Python and Django, with the Django REST Framework as the foundation. A significant part of the project was creating a custom user model for mobile-based authentication. This model was designed to cater to the specific needs of mobile users, providing a tailored authentication experience. The project also involved the implementation of JWT for secure authentication to transmit information between parties as a JSON object securely. Finally, I ensured the protection of web paths using JWT authentication—a critical security measure to ensure that only authenticated users can access certain parts of the web application.

The project's repository is publicly available on GitHub through the link above, and an article detailing this project is available at https://medium.com/@mansha99/django-rest-framework-jwt-custom-user-role-4acb39697638.

HILT and MVVM in Android

https://github.com/mansha99/HiltMVVM
A sample Android app (Java) using Hilt, MVVM, LiveData, Viewmodel, Retrofit, and Hilt. It can be used to bootstrap data and a REST-driven Android app. This project illustrates how we can use Retrofit to fetch GitHub users.

Handling Multiple Asynchronous Calls

https://github.com/mansha99/handling-multiple-calls-async
The client requested detailed updates from their social networks—Twitter, Facebook, and Instagram. These social networks operate on a massive scale, and their response times can be unpredictable. The delay in their response almost appeared as if someone waited for a random integer of seconds before responding. Additionally, there were instances when they responded with an error that would not be in a valid JSON format.

The client needed to be able to run the device and issue the command curl localhost:3000, which would fetch a JSON response containing the desired output from the three social networks, presented in the correct format.

ComUpNow

ComUpNow is an app for proficient stand-up storytellers and comedians; designed to continue composing quickly so you can concentrate on your satire rather than the instruments.

Any idea, you can rapidly add it to your unbounded notes list. Simply open the app, hit "in addition" to fasten, and begin composing. Everything is saved safely and immediately, so don't stress about losing your work.

You can add notes to existing sets or make another set. Drag and drop to reorder the notes and have them prepared individually. Move jokes over, expel, and include until you locate that ideal set.

At the point when you're in front of an audience, you can change to the dramatic mode and have your set ready. The screen will stay turned on and dark. While you perform, you can swipe right or left to demonstrate if the joke landed, then you can return to it later and reshape it.

You can label as needed. Either apply marks from the note screen or add notes to a current name from the names screen. Access notes by the topics that are appropriate for your next set.

Each note is produced with an estimated time for you to perform it. However, you can alter each gig to fit availability.

Article on SwiftUI

https://medium.com/@mansha99/swift-ui-fundamentals-634df221295e
SwiftUI is a declarative approach to creating user interfaces for any Apple platform, including iOS. Developers have to focus on "what" rather than "how." This article helps beginners learn the basic aspects of SwiftUI.

Socialio (Development Phase)

This is a social media app developed using Swift 4x with a Firebase back end containing the following features:

• Authentication using Firebase Authentication
• Sharing pictures and audio
• Likes, comments, and sharing
• Vote Up and Vote Down feature
• Dynamic creation of a portfolio and submit it to influencers for further consideration

My role was translating Zeplin Screen into UI (without storyboard) and connecting it with the Firebase real-time database and Firestore for RW operations.
