Back-end key implementations ⚙️

👉 GraphQL Implementation: We utilize GraphQL as a query language for APIs and a runtime for executing those queries with your existing data. This aids in fetching more efficient and specific data, reducing the amount of data that needs to be transferred over the network and speeding up our applications.

‍👉 Serverless Architecture with Google Cloud Run: To achieve enhanced scalability, we employ serverless computing using Google Cloud Run. This allows for automatic scaling and management of our applications, enabling us to focus more on building great software and less on managing servers.

‍👉 Firebase Storage Integration: Our projects leverage Firebase Storage for storing and retrieving user-generated content like photos, videos, and other large files. With Firebase, we deliver robust and secure file upload and download capabilities in our applications.

‍👉 Complex MongoDB Aggregation Pipelines: We utilize MongoDB's powerful aggregation framework to process data and return computed results, allowing us to handle complex data transformation in an efficient and streamlined manner.

‍👉 Database Queries Optimization (Caching): To speed up our applications and reduce database load, we use caching techniques for optimizing database queries. This results in an improved user experience, with quicker data retrieval and responsive application behavior.

‍👉 Custom Firebase Authentication System: For robust and secure user authentication, we've implemented a custom Firebase Authentication system. This provides a backend service that helps in authenticating and managing users who access our applications.

‍👉 Support of Multiple Timezones (Date Formatting): To ensure seamless user experience across the globe, our applications are equipped to support multiple timezones and date formatting. This feature ensures consistency of date and time representation regardless of the user's geographical location.

‍👉 Multiple User Roles: Our systems are designed to support multiple user roles, providing differentiated access and permissions based on the roles assigned to each user. This ensures a secure, controlled environment where tasks and information access are effectively managed according to the responsibility of each role.
