About

Abdullah Ghani

I run Greyphase Technologies from Kolkata as a sole proprietorship, building web and mobile applications for businesses and startups across India.

Every project is handled by me personally — scoping, design, development, deployment and support. I take on a limited number of projects at a time so each one receives full attention.
