Client Feedback

What clients say

"Subhra built our entire SaaS dashboard from scratch — React frontend, Node.js API, and PostgreSQL backend. Delivered on time, clean code, and he was available whenever we needed him. Highly recommend."

J

James Whitfield

Founder, Finova Labs · London, UK

"We needed a full e-commerce overhaul in under 6 weeks. Subhra delivered a pixel-perfect Next.js storefront with payment integration and CMS. The site now converts 3× better than our old one."

P

Priya Nair

CTO, GreenCart · Singapore

"We hired Subhra for a WiFi management API project. His technical depth is impressive — he understood our infrastructure requirements immediately and built something robust and well-documented."
