A friend recently asked me how to get started with backend development, so I put this together. It's a curriculum based on two years of my own missteps, so the chance of failure is low.
Months 1–3: CS Basics + Networking
- You absolutely need to grasp TCP/IP and HTTP concepts. I recommend reading one Hanbit Media book thoroughly.
- For data structures and algorithms, just the basics (arrays, linked lists, stacks, queues). Go deeper later.
Months 4–6: Language + Database
- Choose either Java (Spring) or Python (Django). If you're thinking about getting a job, Java is definitely the safer choice.
- SQL basics plus index concepts.
Months 7–9: Project
- Complete a CRUD app -> optimize queries -> add login/authentication.
- You must deploy it. AWS Free Tier is enough.
Months 10–12: Portfolio + Resume
- Deep-diving into one project is better than skimming three.
- Describe the technologies you used and the problems you solved in detail on your resume.
If you just follow this sequence, you'll be ready to apply for backend roles within a year. Surprisingly, a lot of people rush to finish in 6 months, but most of them end up quitting halfway.
