Roadmap

Backend

User Authentication System

Topics Covered: Backend language & framework, database, authentication & authorization (session-based or JWT), API security basics.

Implement user registration and login functionality for a simple application. Features should include:

  • User registration (username, password, email).
  • User login and logout.
  • Password hashing and secure storage.
  • Protecting API endpoints that require authentication (e.g., notes API project).
  • Consider using JWT (JSON Web Tokens) for token-based authentication.

Simple URL Shortener Service

Topics Covered: Backend language & framework, database, API design, URL redirection, data modeling.

Create a service that takes a long URL and generates a shorter, unique URL. Features should include:

  • API endpoint to submit a long URL and receive a short URL.
  • Database to store mappings between short and long URLs.
  • Redirection logic: when a short URL is accessed, redirect to the original long URL.
  • Consider adding analytics (click counts) as a bonus.

Cloud

Containerized Web Application Deployment

Topics Covered: Docker, containerization, cloud compute (containers - AWS ECS/EKS, Google Kubernetes Engine, Azure Kubernetes Service), basic cloud deployment.

Take one of your backend projects (e.g., the To-Do List API).

  • Dockerize the application (create a Dockerfile and build a Docker image).
  • Deploy the Docker image to a cloud container service (e.g., AWS ECS Fargate for simpler setup, or explore Kubernetes for more advanced orchestration).
  • Set up basic monitoring for your containerized application.

System Design

Implement Caching in a Backend API:

Topics Covered: Caching strategies (in-memory caching, distributed caching with Redis or Memcached), performance optimization, backend development.

Take one of your backend API projects (e.g., To-Do List API).

  • Implement caching for frequently accessed data (e.g., task lists, blog post details).
  • Use an in-memory cache initially (like a dictionary/map in your backend language).
  • Optionally, integrate a distributed cache like Redis for more scalability.
  • Measure the performance improvement with and without caching.

Add Logging and Monitoring to a Web Application:

Topics Covered: Logging best practices, monitoring tools (CloudWatch, Stackdriver, Prometheus/Grafana, ELK stack), application observability, DevOps practices.

Enhance one of your backend projects with robust logging and basic monitoring. Implement structured logging in your backend code to log important events (requests, errors, performance metrics).

  • Integrate with a logging service (e.g., CloudWatch Logs, Google Cloud Logging).
  • Set up basic monitoring dashboards to track application health and performance metrics (e.g., request latency, error rates).
