## About

Software Engineer with 3\+ years of experience building production\-grade backend and full\-stack systems\. IIT Kharagpur graduate\. On the backend, I work on transaction workflows, exchange integrations, asynchronous processing, high\-frequency data pipelines, and real\-time data synchronization, with a focus on reliability, performance, and scalable service design\. On the frontend, I've worked on transaction journeys and the migration to a Module Federation\-based micro\-frontend architecture, and built a WebSocket streaming system using Shared Workers that reduced real\-time market\-data lag from \~5s to <0\.5s\.
