What Should I Learn Next as a Backend Developer?

Focusing on backend is definitely the way to go since you’re not into front-end. Areas like database optimization, API design at scale, and DevOps (think AWS, Docker, and Kubernetes) are highly valued. Also, learning about security aspects like OAuth and encryption will enhance your marketability significantly. Combining backend skills with cloud knowledge and a bit of system design expertise will make you very appealing to employers!

It's great that you've already got real-world experience with your CRM! Before diving into specific technologies, consider thinking about what you want your ideal work situation to look like. Are you looking to start your own projects, or do you see yourself working for a big company? This can help define which skills to prioritize. If entrepreneurship appeals to you, focusing on full stack skills might be beneficial, but overall, just keep exploring and find your niche.

You're already ahead with that CRM project, but don't wait too long to launch it! Real user feedback can teach you a lot more than you expect. To solidify your backend skills, I suggest you deeply learn one backend language like Kotlin, Go, or Python. Also, get familiar with DevOps fundamentals like Docker and CI/CD. Diving into database design and caching strategies like Redis will really set you apart. System design basics can also give you a major edge in the job market—understand how different components work together in large systems!
