About

I’m a backend engineer with 4+ years of experience designing, building, and maintaining systems. I focus on managing my work to align with business priorities while maintaining technical quality. I’ve worked extensively with Golang but can adapt to other technologies and enjoy solving problems to make systems better. My work includes building services from scratch, optimizing existing ones, and ensuring they scale effectively. I’m passionate about continuously improving my understanding of backend systems. I like exploring how different systems are designed and believe in learning through practical. Currently, I’m working on GoFast, an in-memory cache library for Golang focused on improving time efficiency. (Check it out here: https://github.com/raghavgh/gofast) If you’re interested in pairing on interesting hobby projects or have a group working on something exciting, I’d love to contribute and collaborate during weekends. I’m always open to opportunities that help me learn and grow while sharing knowledge with others.
