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 deeply about software that is accessible, performant, and genuinely a pleasure to use.
My work spans from consumer-facing fintech products serving thousands of UK savers, to developer-facing SDKs powering Bluetooth-enabled smart access hardware. I enjoy the full spectrum — pixel-level UI polish and low-level protocol design are two sides of the same coin.
Currently at Allegion, I'm building the iOS BLE SDK stack that connects mobile apps to intelligent physical-security hardware. Previously at HCL and Infosys, I led teams, designed systems, and shipped products used by hundreds of thousands of people.
"I think clean architecture and pixel-perfect UI aren't opposites — they're the same obsession viewed from different angles."
