Hello,
I’m Calwa — a Software Engineer.

I'm an Informatics student at Telkom University with a strong focus on backend engineering.

I design APIs, manage databases, secure authentication flows, integrate AI models, and deploy software that is ready for real-world use.

While backend is my main focus, I’m also comfortable working across frontend, mobile, and DevOps workflows to deliver complete digital products.
