About Koushik Puppala
Software Engineer – Full Stack with 3 years of experience building end-to-end web features using React, Next.js, Node.js and PostgreSQL.
I build scalable, high-performance web applications — from the rendering layer through to the APIs and data behind them. My work centres on frontend performance, clean architecture and dependable backend integration.
I'm currently a Full Stack Developer at Earnest Data Analytics, where I work on SEO-friendly Next.js architecture, Node.js and Express APIs, and AWS infrastructure for production workloads. Before that I worked across internships and a long-running university web team, and I've been maintaining my own open-source portfolio since 2020.
I'm based in India and reachable at koushikpuppala@koushikpuppala.com.
