About Me

Prayag Sridhar

I am Prayag Sridhar

I work at Capital One as a software engineer. Day to day, I build finance modules, analytics dashboards, and transaction processing systems. My stack here is Java, Spring Boot, React, and PostgreSQL. I got dashboard response times down by 65% and pushed expense categorization accuracy to nearly 90%.

Before this, I spent two years at Tata Consultancy Services where I worked on data pipelines that handled 5 million events a day. That was PySpark, Apache Spark, and AWS. We kept uptime at 99.9%. I also did an internship at Softeq in Boston, building real-time traffic monitoring with WebSockets and Node.js.

I am open to frontend and full-stack roles. I like owning a feature from the database layer all the way to what the user sees.
