About

10 years. 12+ production apps. Millions of users. That's the short version. I'm a Senior iOS Engineer (moving into Lead / Staff) who specialises in SwiftUI, UIKit, The Composable Architecture (TCA), and Combine. My work sits at the intersection of clean system design and shipped product — not one or the other. At Raw Engineering, I led the full SwiftUI migration across the iOS platform, cut UI development time by 40%, and built a reusable SwiftUI component library that shaved 25% off GTM cycles. I've integrated Razorpay, PayU, and Stripe payment SDKs end-to-end — checkout, webhooks, refunds, compliance. I've shipped white-label apps for NBA franchises (Miami Heat, San Antonio Spurs, Memphis Grizzlies), HIPAA-compliant healthcare platforms, and fintech investment dashboards — all in production. What I focus on: → Architecture that doesn't age badly — TCA, Clean Architecture, Modular SPM → Payment systems that don't break — Razorpay, PayU, webhook reliability → CI/CD pipelines that free up engineers — Bitrise, Fastlane, 30% faster submission cycles → Crash rates that go down, not up — resolved memory leaks reducing crashes by 30% Currently building carCaller — a privacy-first masked voice-call platform for India and UAE, using Twilio + MSG91 with a Supabase + Vercel edge backend. It's the kind of problem I enjoy: real infrastructure, real constraints, real users. I also founded Ivory Lighthouse, a recruitment tools initiative — because I understand talent pipelines from both sides. Open to Lead iOS Engineer, Staff Mobile Engineer, or Principal iOS roles. Mumbai-based, open to hybrid or fully remote. If you're building something where mobile is a first-class product decision, I'd like to hear about it. 🛠 Swift · SwiftUI · UIKit · Combine · TCA · Core Data · Realm · GraphQL · Firebase · Supabase · Fastlane · Bitrise · Razorpay · PayU · Stripe · Xcode Instruments · SPM
