Sabarinathan J
Full Stack Web Developer crafting scalable products with React, Node.js and AI engineering. Currently pursuing B.E. in Artificial Intelligence & Data Science.
About
Engineering thoughtful, intelligent software.
I'm Sabarinathan, a Full Stack Web Developer with a year of industry experience at Assuvar.com, where I built and shipped client-facing web applications using React, Tailwind, and Node.js.
I'm pursuing a Bachelor's in Artificial Intelligence & Data Science while building AI-powered tools — from RAG assistants to context-aware chatbots — that bridge engineering and intelligence.
I care about scalable architecture, considered interfaces, and the small interaction details that make products feel inevitable.
