# Project Discovery Call with Rudra Sutariya

> A 30-minute call to talk through what you want to build. We'll cover what the product needs to do, what's realistic in your timeline and budget, and whether I'm the right person for it. If it's a fit, I'll follow up with a written scope and a fixed quote. No preparation needed. Bring your idea, designs if you have them, or just a rough outline.
