What I'm looking for

I’m looking for a scope where my technical decisions affect more people and the problems don’t have obvious answers. I want to lead scalable iOS architecture, product performance, developer experience, and high-impact engineering teams.

At Swiggy, I lead iOS delivery across Snacc, Toing, IRCTC, and the iOS Tech Charter, managing seven engineers across three streams. I’ve driven Shell Modularisation, a unified Design Language System, SPM migration, and app-size initiatives that reduced shell-app download size by 4–6 MB and install size by 6–9 MB.

I build products as well as platforms: I delivered Snacc’s Storefront 2.0, improved home-page load time by 40%, reduced PDP open latency from 800 ms to under 200 ms, and helped maintain a 99.99% crash-free rate. Across nine years in iOS, including Box8 and Novoinvent, I’ve owned architecture, performance, developer experience, mentoring, hiring, and the technical decisions that scale across teams.
