A Bit About Me

I'm Vasant Patil, a Senior iOS Engineer with 5+ years of experience shipping mobile apps across banking, IoT, and enterprise sectors.

I care about the full stack of mobile craft — architecture that scales, interfaces that feel right, and SDKs that make other developers' lives easier.

Clean architecture and pixel-perfect UI aren't opposites — they're the same obsession viewed from different angles.
