Backend Development

Backend developers build the server-side: APIs, business logic, databases, authentication, security, and the infrastructure that powers apps. Day-to-day you design and build REST/GraphQL APIs, model and query databases (SQL and NoSQL), handle auth and security, write tests, and increasingly deploy to the cloud with containers and CI/CD.

Suits: logic- and systems-oriented people who like data modeling, performance, correctness, and "how it works under the hood," and who are comfortable with abstraction and less visual feedback.

• Demand: Very high and structurally durable. Industry reporting ranks back-end and full-stack as the most in-demand roles. Per BLS OOH (2024–34): software developer employment is projected to grow 15% with ~129,200 openings per year and a median annual wage above $130,000.
• Entry salary (US): ~$75k entry (PayScale 2024), rising to $120k+ with experience.
• In-demand skills: cloud (AWS/Azure/GCP) is now near-mandatory — roughly three-quarters of backend roles in 2025 require cloud; plus microservices, Docker/Kubernetes, SQL + NoSQL, REST/GraphQL, CI/CD.
• Remote: High; backend is heavily represented in remote and outsourced/staff-augmentation work.

• You love logic, algorithms, data, and systems thinking.
• You care about performance, scalability, and security.
• You're comfortable without constant visual feedback.
• You want a high-paid specialist track and don't mind a steeper learning curve.

1. 1

   Fundamentals: One language well (Python or JavaScript/Node); Git; command line/Linux basics; how the web/HTTP works.

2. 2

   Core skills: Build REST APIs; relational databases (PostgreSQL/MySQL), SQL, schema design; authentication/authorization; error handling.

3. 3

   Framework: Node.js + Express (or Python + Django/FastAPI); ORM; validation; testing.

4. 4

   Tools: Docker, environment/secrets management, a NoSQL store (MongoDB/Redis), CI/CD (GitHub Actions), one cloud platform (AWS basics), API testing (Postman).

5. 5

   Portfolio projects: Ship 3–4 deployed APIs/services.

1. RESTful API with full CRUD, auth (JWT), and a database (e.g., a blog or task API).
2. A real-world integration service (payments, email, or a third-party API) with tests.
3. A dockerized app deployed to the cloud with a CI/CD pipeline.
4. A small microservice + caching (Redis) demonstrating scalability awareness.

7–12 months — longer than frontend because of databases, security, and cloud/DevOps fundamentals.
