About

Software Development Engineer with 3 years of experience building full-stack and backend systems across startup and high-scale environments. At Hoomanely, I own the full engineering stack — Next.js/React frontends, Spring Boot/Python backend services, AWS infrastructure (DynamoDB, Lambda, Cognito, AppSync, S3), and Flutter mobile apps. I've shipped a consumer product end-to-end, from architecture to CI/CD to production, in a team where every engineer is expected to own what they build. Before that at BYJU'S, I led the in-class experience for the BYJU'S Premium app — built from scratch in Flutter with native Kotlin/Swift integrations, running at scale for millions of learners. What I'm good at: - Designing and shipping backend systems that scale (distributed systems, microservices, cloud-native AWS) - Building full-stack products fast without cutting corners on reliability - Bridging the gap between a user problem and a production-ready solution - Working across mobile (Flutter, iOS, Android) and web (Next.js, React) I also have hands-on experience with embedded systems — BLE protocols, FreeRTOS on ESP32, STM32, and custom Yocto Linux — which has made me a much sharper engineer overall. Currently open to Software Engineer / SDE II roles in Bengaluru (on-site or hybrid) or remote. If you're building something interesting, let's talk.
