Ajay Upadhyay is a freelance full-stack web developer in Lucknow with 1+ years of experience building production web apps with React, Next.js, Node.js, and the MERN stack. I work with founders, startups, and agencies to turn ideas into reliable, scalable products.
Over time I've learned that businesses don't just need code — they need tech that drives growth, eliminates manual work, and scales smoothly. So beyond websites and dashboards, I build AI agents and automation workflows, set up advanced integrations (payments, webhooks, WhatsApp Business API), and run high-converting Meta ad campaigns.
I use modern AI tools like Claude Code, Cursor, and GitHub Copilot to ship faster without compromising quality. My freelance studio is open — I handle the complete engineering and digital execution side so you can focus on growing your business.
