Engineer by day. Shipper by night.

I'm Manuj Rai — a full-stack & AI engineer based in Ahmedabad. I build production AI agents and enterprise systems at Fibre2Fashion by day, and ship India-market web products as a freelancer by night. Two stacks, one obsession: shipping things that earn their keep.

Two stacks, two audiences

For HR & Hiring Managers

By day — Software Engineer

I joined Fibre2Fashion as an intern building ASP.NET + SQL Server systems, grew into Python for data pipelines and large-scale scraping (requests, Playwright, Selenium), and now build AI agents in production — RAG, LangChain, tools, multi-step workflows.

For Founders & Clients

By night — Freelance Full-Stack

I help founders launch India-market web products fast — Next.js + Supabase + Razorpay, with Cloudinary for media, MSG91 OTP, Resend/SMTP for email, and AI baked in. Idea to live URL in weeks.
