RESTful API with Authentication and Authorization:

Develop a RESTful API using frameworks like Express or Django, incorporating authentication and authorization mechanisms to secure the endpoints.

Task Scheduling and Background Jobs with a Job Queue:

Implement a task scheduling system using a job queue like Bull or RabbitMQ, allowing asynchronous execution of tasks and background job processing.

Real-time Chat Application with WebSockets:

Build a real-time chat application using WebSockets and frameworks like Socket.io or Django Channels, enabling instant messaging between users.

Microservices Architecture with Communication Protocols:

Design and implement a microservices architecture using tools like Docker and Kubernetes, and establish communication between services using REST APIs or message brokers.

Scalable and Fault-Tolerant Distributed Systems:

Build a distributed system that can handle high traffic and ensure fault tolerance by leveraging technologies like Apache Kafka, Apache Cassandra, or Redis.

Building a Content Delivery Network (CDN):

Create a CDN using technologies like Nginx or Varnish Cache to efficiently deliver static assets and improve the performance of web applications.

Implementing a Caching Layer for Performance Optimization:

Integrate caching mechanisms like Redis or Memcached into your backend system to cache frequently accessed data and enhance application performance.

Designing and Optimizing Relational Database Schemas:

Develop a database schema for a complex domain, optimizing queries, relationships, and indexing strategies to ensure efficient data retrieval and storage.

Building a Web Scraping and Data Processing Service:

Create a service that collects data from web sources using tools like Scrapy or Puppeteer, and process and store the data in a structured format.

Creating an Analytics Dashboard with Data Visualization:

Build an analytics dashboard using frameworks like React or Angular, integrating with data visualization libraries like D3.js or Chart.js to provide insightful data representations.
