Week 7 of #100DaysOfCode: Back to the Fundamentals

In week 7 of #100DaysOfCode, the author paused new projects to strengthen core backend knowledge, especially Spring fundamentals.

The focus was on Dependency Injection, the IoC container, Spring AOP, logging, Spring Security, OAuth2, BCrypt, and WebFlux.

They also revisited SOLID principles and GoF design patterns to better understand maintainable, scalable system design.

The week additionally included exam prep, CV updates, job applications, and an AI mock interview, but no new project was shipped.

Overall, the post highlights both deeper framework understanding and active preparation for backend roles.
