Software Engineer documenting what I learn, build, and understand.

Hi, I'm Yashika, a Software Engineer passionate about understanding how software works beneath the surface. I write practical, beginner-friendly deep dives on web development, TypeScript, Git, backend development, system design, databases, and modern software engineering. My goal is to simplify complex concepts through real-world examples, diagrams, and hands-on exploration.
