About Me

Hi, I’m Prem Kumar.

I’m a Full-Stack Software Engineer with 2+ years of experience building, shipping, and maintaining production web applications at Metapointer Labs.

I specialize in building robust backend services with LoopBack 4 and Node.js, crafting intuitive user interfaces with Angular, and managing cloud infrastructure on AWS. I’ve also led CI/CD automation with Azure DevOps and achieved a 56% reduction in AWS costs through infrastructure optimization.

I’m passionate about writing clean, efficient code and I’m always excited to learn new technologies and take on challenging problems.
