About Me

Hi, I'm Karthick — a backend developer specializing in Java and Node.js, with a strong focus on building scalable, reliable, and high performance applications. I enjoy solving complex problems and turning ideas into efficient, maintainable systems.

Alongside backend development, I have experience with DevOps practices and cloud infrastructure, and I'm comfortable working across the stack when needed. I believe in writing clean code, designing robust architectures, and building products that deliver real value.
