In today’s digital age, backend engineers, also known as back-end system engineers, play an important role in building and maintaining the infrastructure of applications. To become a good backend engineer, you need to master a range of skills. Here are some essential skills for you.
1. Programming Languages & Frameworks
- Java : One of the popular and powerful programming languages, suitable for large enterprise applications. Spring Boot is a popular Java framework, allowing rapid development of web applications and microservices.
- Python : Preferred for web and backend development due to its flexibility and rich library. Django helps build full-stack web applications, while Flask focuses on lightness and flexibility.
- Ruby : Known primarily for Ruby on Rails (RoR) – a framework for building web applications quickly and in an organized manner. RoR follows the principle of “Convention over Configuration”, which helps to minimize configuration and speed up development.
- Go (aka Golang): Designed by Google, Go is a high-performance programming language suitable for developing distributed systems and applications. With a powerful standard library and static data type system, Go helps build efficient and secure applications.
- Node.js : Not a programming language, but a server-side JavaScript execution environment. Combined with Express.js (a popular framework), Node.js helps develop high-performance and scalable web applications.
Depending on the goals and requirements of the project, backend engineers can choose the appropriate programming language and framework. It is important to master the grammar, usage context, and understand the support community behind each language/framework to solve problems and improve skills.
2. Working with databases
- SQL (Structured Query Language): This is a query language for relational databases such as MySQL, PostgreSQL. This skill helps backend engineers understand how to store, query, and update data.
- NoSQL : Databases like MongoDB, Cassandra work on non-relational model, suitable for big data and need flexibility.
- Optimization: Query optimization skills to ensure good performance.
- Transactions: Understand how to manage transactions and ensure data integrity.
- Migrations: Manage and apply schema changes safely.
3. API Design and Integration
- REST: This is an architectural style for APIs. A RESTful API uses HTTP methods like GET, POST, PUT, DELETE to perform operations on data.
- GraphQL: An API-specific query language that allows clients to request more specific information than REST.
- WebSockets: Allows two-way connection between client and server.
- Middleware: Layers that handle the request and response in an application.
4. Network and Security
- HTTP/HTTPS: These are communication protocols between client and server. HTTPS adds a layer of encryption to secure information.
- Security: Backend engineers need to know how to protect data by encrypting, using tokens (like JWT), and applying other security principles.
- DDoS Mitigation: Know how to prevent and handle DDoS attacks.
- OAuth & SSO: Popular authentication and authorization models.
5. Server Management and Deployment
- Docker: Docker allows “packaging” an application and its environment into a “container”, making deployment consistent across all environments.
- Kubernetes: A system for managing, scaling, and automating the deployment of containers.
- CI/CD: Automated process from source code testing to product deployment.
- Monitoring & Logging: Monitor system activity and log to troubleshoot.
6. Knowledge of system knowledge
- Microservices: This concept involves breaking down an application into multiple independent services, each performing a specific function and able to be developed and deployed independently.
- Load Balancing: Distribute load across multiple servers.
- Caching Strategies: Use cache to speed up data access.
7. Version Control
- Git : Is a source code management tool that helps track and manage changes in source code, as well as merge source code from multiple developers.
- Branching Strategies: Like Gitflow, track and manage source code branches.
8. Soft Skills
- Communication: This skill helps backend engineers exchange ideas, information, and data clearly and effectively with teammates and stakeholders.
- Teamwork & Collaboration: Work effectively in teams and share knowledge.
- Problem Solving: Approach and solve problems systematically.
- Self-learning: Technology changes rapidly, the ability to self-learn and update knowledge is important.
Conclusion
Becoming a good backend engineer requires not only a solid grasp of techniques and technologies, but also soft skills and systems thinking. To truly stand out in this field, you need to constantly learn, update your knowledge, and be able to flexibly apply the knowledge you have learned into practice.
