## Headline

Software Development Engineer 2 · Full Stack & Backend \| Next\.js · Flask · AWS · Distributed Systems \| Ex\-BYJU’S

## 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\.
