My Journey

About Me

Krishna

I am a passionate BCA graduate with a deep fascination for the intersection of clean software engineering and robust cloud infrastructure.

My journey began as a full-stack developer building MERN applications. As my applications scaled, I realized the critical importance of deployment automation, reliability, and security. This drove me to expand my expertise into DevOps, containerization, and Cloud Web Architecture.

Today, I specialize in packaging applications into Docker containers, orchestrating them with Kubernetes, writing Infrastructure as Code (IaC) via Terraform, and automating deployment workflows on Amazon Web Services (AWS) using GitHub Actions CI/CD.
