2) Backend Development (Server-Side Technologies)

The back end handles business logic, database interactions, authentication, and application security.

Java as the Backend Language

• Java SE (Standard Edition) – One key aspect of Java SE (Standard Edition) is understanding main concepts such as OOP, collections, exception handling, and multithreading.
• Java EE (Enterprise Edition) – This is advanced Java for enterprise-level applications.

Backend Framework: Spring Boot

• Spring Boot – Java developers leverage this framework to develop web applications and generate flexible, secure distribution solutions.
• Spring MVC – This handles the Model-View-Controller (MVC) architecture for web applications.
• Spring Security – Applications gain secure authentication and authorization support from this framework.
• Spring Data JPA (Java Persistence API) – This simplifies database interactions.
• Spring Cloud – This is useful for building microservices-based architectures.

RESTful APIs & Microservices

• RESTful APIs – These help frontend and backend systems manage communication through these web services.
• GraphQL – This flexible data retrieval method functions as an alternative to REST APIs.
• Microservices Architecture – Microservices architecture divides an application into independent deployment units that work separately from one another.

3) Database Management Systems (DBMS)

Databases maintain a database system that facilitates the storage and retrieval of application data. Full-stack developers need expertise in both SQL and NoSQL database systems.

SQL Databases (Relational Databases)

• MySQL – MySQL stands as one of the most common relational databases worldwide.
• PostgreSQL – This is an advanced open-source relational database system.
• Oracle DB – This database system serves large commercial organizations.

NoSQL Databases (Non-Relational Databases)

• MongoDB – Document-based NoSQL databases process massive amounts of data for organizations.
• Cassandra – This distributed NoSQL database design provides high scalability with its implementation.

ORM Tools (Object-Relational Mapping)

• Hibernate – The Java database mapping software, Hibernate, is a widely used ORM tool.

4) Version Control & Code Management

Developers can follow change histories through version control methods while working together and effectively handle their programming.

Essential Tools

• Git – this is a distributed version control system.
• GitHub / GitLab / Bitbucket – These are platforms for hosting and managing repositories.
• CI/CD Pipelines (Continuous Integration/Continuous Deployment) – These automate testing and deployment.

5) Deployment & Cloud Services

A full-stack developer must be familiar with deployment strategies and cloud platforms to host applications.

Hosting & Deployment Platforms

• AWS (Amazon Web Services) – This provides services for deployment and cloud computing and infrastructure provisioning.
• Google Cloud Platform (GCP) – This is a cloud-based hosting and computing service.
• Microsoft Azure – Applications can be deployed through this cloud computing service.
• Heroku & Netlify – These are platforms for easy cloud-based application deployment.

Containerization & DevOps Tools

• Docker – Docker enables the development of minimal-size containers to execute programs in multiple settings.
• Kubernetes – This system handles deployment and automatic scaling of containerized applications.

Security Best Practices for Full Stack Developers

• Use HTTPS for All Communication: All data transmissions should always use SSL/TLS for protection. The encryption system protects sensitive data by securing the user and server connection.

• Implement Strong Authentication & Authorization: Users should authenticate through JWT (JSON Web Tokens), OAuth 2.0, or Session-based Authentication methods for authentication verification. Each user must receive permission to view data and interact with authorized functions.

• Sanitize User Input to Prevent SQL Injection & XSS: User data must pass through an approval system prior to entering the database to clean up harmful content. Users should never provide direct input for database queries. Databases should be accessed through prepared statements together with ORMs, including Hibernate.

• Securely Store Passwords (Hashing & Salting): Keep passwords away from plain text storage formats. Secure hashing algorithms, bcrypt, argon2, and PBKDF2, should be used for password protection, and individual salts should be created for each user.

• Use Role-Based Access Control (RBAC): To prevent unauthorized access to sensitive information, specific functions should only be accessible according to defined user roles, such as admin, user, or guest.

• Secure APIs with Proper Access Control: RESTful API development requires implementing API key validation, rate limiting, and token-based authentication to prevent unauthorized users from accessing systems.

• Avoid Exposing Sensitive Information in Responses: Every API and UI response must exclude all stack traces, database information, or internal error messages. The server keeps track of all error details while showing users generic notification messages.

• Keep Dependencies Updated: Stay updated by periodically updating your framework elements, plugins, and library components. The OWASP Dependency Check and NPM audit can help you find recognized vulnerabilities affecting your software stack.

• Implement CORS Policies Wisely: You should employ CORS control of cross-origin requests to stop unauthorized websites from accessing your APIs.

• Monitor & Log Suspicious Activity: Your system requires monitoring tools that track irregular actions between failed login attempts and unusual API events. Security alerts need to be established to detect potential breaches.
