What Clients Say

Don't just take my word for it. Here's what my clients have to say about working with me.

"I run a clothing business in Kolkata and needed a proper online store. Raj built the full website with a smooth payment setup and an AI bot that handles customer queries automatically. Since the launch, our sales have improved and I don't have to spend all day answering basic questions. Very happy with the results!"

Debraj Chakraborty

Business Owner, Kolkata

"He managed the complete backend for my astrology app. From real-time notifications to automated alerts using cron jobs, everything works perfectly. The best part is the system never lags, even with many users. I've already started discussing the Version 2.0 update with him because his work is top-notch."

Suman Das

Client from Kolkata

"As a tax professional, I handle a lot of private financial papers. I needed a tool to split and compress large PDFs without uploading them to any random website. The tool Raj built works entirely on my computer, so my data stays safe. It's fast, simple, and has made my daily paperwork much easier."
