# Mridul Dey on Tal

## Headline

Associate at Goldman Sachs

## About

I'm a software engineer with strong experience across backend, frontend, and big data systems\. I work extensively with Java \(Spring Boot\) for building scalable services and React for developing intuitive, data\-rich UIs\. A significant part of my work involves Hadoop\-based distributed systems—designing and optimizing large\-scale data pipelines, and improving performance across high\-volume MapReduce workflows\. I've also built dashboards that enhance visibility into critical infrastructure and support smarter operational decisions\. I focus on writing clean, efficient code and delivering solutions that are reliable, user\-centric, and built to scale\.
