# 👋 Discovery call with Bhupesh Bhatt

> A quick 30-min chat to talk through your project — what you're building, what you need, and whether we're the right fit. No pitch, no pressure. If we click, I'll walk you through how I work, rough timelines, and what it'd cost to get started. If you've got something in mind (or even just a rough thought), you're in the right place. Fair warning though - "I ask a lot of questions. That's how good projects start." Prefer email? 🡺 hello@bbhatt.com.np
