Hi there, I’m Varun Dutia 👋
I’m a Software Engineer passionate about building scalable backend systems, distributed applications, cloud-native services, and AI-powered software.
I enjoy understanding how systems work under the hood, from databases and caching to networking, distributed coordination, and large-scale architectures. My goal is to build software that is reliable, performant, and maintainable.
