About Satish Chaubey

Passionate Full Stack Engineer

I am a **Full Stack Engineer** with **0+ years of experience** building high-throughput web applications using **Next.js 16** (App Router & React Compiler) and **React 19.x**, payment engines, SaaS dashboards, and AI architectures (**RAG & CAG context caching**). Based in Uttar Pradesh, India, I focus on crafting clean, resilient JavaScript/TypeScript applications across the full web stack.

Over the past 3 years, I have architected high-traffic bill payment systems, integrated payment gateways (PayU, Razorpay, BBPS), AI RAG/CAG document search pipelines, and developed enterprise digital banking platforms.
