Back-end Developer - level 2

At level 2 of the Back-end Developer profile you go beyond the basics of building APIs and data structures and start focusing on robustness, security, and scalability in real-world environments. You learn how to design systems that can securely authenticate users, protect data, handle higher loads, and remain observable and maintainable as they grow more complex.

During this level you work on products such as authentication and authorization, application security, caching and performance, microservices and service boundaries, monitoring and observability, and messaging and integration. Together, these products deepen your understanding of how professional back-end systems are built, operated, and evolved over time.
