Hi, I'm Kanishka Shashi. I'm a Computer Science (AI & ML) student passionate about building, analyzing, and explaining technology. This blog is where I simplify complex concepts into practical, beginner-friendly guides. You'll find articles on Web Development, System Design, AI & LLMs, Data Analytics, SQL, Git/GitHub, and software engineering best practices. I enjoy exploring how modern technologies work under the hood and sharing insights through real-world examples and hands-on projects. Whether you're a student, developer, or tech enthusiast, I hope these articles help you learn something new and build better software. Learning in public. Building consistently. Sharing everything I discover.
