About

Hey, I'm Rajat 👋 I'm a Software Development Engineer at Salesforce with 4+ years of experience building scalable backend systems and REST APIs using Java, Spring Boot, and JavaScript. I enjoy solving hard problems — from optimizing distributed systems for 10x performance gains to building agentic AI tools that turn manual workflows into guided experiences. I'm a graduate of NIT Allahabad (B.Tech, Information Technology), and beyond my day job, I'm into open-source contribution (GSSoC, FossAsia) and exploring how AI-assisted tools like Claude Code and Cursor are changing how we build software. Check out my experience and projects below, or reach out: 991rajat@gmail.com
