Frontend Developer | React & Next.js

Hi, I'm Nikhil Kumar

Fusing AI and UI Craftsmanship with Next.js Precision

I transform ideas into exceptional digital experiences with AI-powered solutions, performance-driven architecture, and scalable, production-ready code.

ABOUT ME

👋 I'm Nikhil Kumar — a MERN Stack Developer with 2.5 years of experience, currently working at Purecode AI.

While I work across the full stack (MongoDB, Express.js, React.js, Node.js), my strength lies in building high-performance frontend applications using React.js, Next.js, TypeScript, and Tailwind CSS.

I specialize in crafting fast, accessible, and SEO-optimized web experiences — improving Core Web Vitals, leveraging SSR/ISR, and ensuring strong search engine visibility through technical SEO strategies. My work has helped drive significant improvements in organic traffic, page load performance, and user engagement.
