I'm Paurush Rai — a Senior Product Engineer based in India: a frontend core with full-stack range, and 5+ years building enterprise web platforms, AI-driven applications, and developer-productivity tools. My work spans complex B2B dashboards, a 1EdTech-certified LMS integration, and custom Jira and VS Code plugins.
I care deeply about performance, clean architecture, and shipping things that actually matter. Whether it's building a greenfield franchise portal from scratch, engineering real-time AI interview workflows, or developing internal tools that save the business thousands of dollars annually, my focus is always on work that measurably moves the needle.
Outside of work I'm usually spinning up a side project, automating a tedious workflow, or reaching for a library I've never touched before — I like the friction of learning new tools in real contexts.
