About

A balanced blend of Realist and Popular Sanguine, with a dash of Perfect Melancholy for good measure. I turned my passion for building things into a profession—starting with Android app development, which ignited my lifelong love for programming and tech. I specialize in Java and Go (first loves!), with a full-stack toolkit that includes Spring Boot, React, and NestJS. I’m constantly leveling up in TypeScript and Python, and recently, I’ve been deep-diving into Docker, cloud-native development, and modern DevOps practices. As a Certified AWS Engineer, I build robust, scalable cloud solutions and bring a pragmatic, automation-first mindset to every project. I’m proud to have been honored with the Google India Scholarship (2018) and to be an active contributor in the Google Developer and Assistant communities. Beyond my day job, I love experimenting with open-source AI, creating side projects (like Stephen: an LLM-powered developer assistant, and Horcrux: an extensible AI framework), and sharing my learnings through my tech clubs and blog series (The O(n) Club, The Mutex Club).
