UIKit · Swift · Production releases

Core commerce and engagement features taken live early in tenure — still foundational to the apps today.

Cart Revamp — production release with Xclusive points animation improvements
Referral — install & sign-up flow + incremental updates, shipped on schedule
Contactability: WhatsApp Login, Unify OTP, Bureau Removal, POP Enrollment, Ring sizer, One Missing Info
Project Genie (launched): store appointment / try-at-store, session lat/long, Call Store CTA; live support

SSL Pinning · Security fixes · Ruby/MAPI · Firebase

Platform work spanning mobile security, supporting backend (MAPI), performance, and production stability.

Security: implemented SSL pinning; config-endpoint cache hardening; contributed to security / Sonar-related quality fixes; documented SSL pinning & custom traces; identity/trust flows via ID Verification and age restriction
Supporting backend (MAPI): high volume of Ruby/MAPI tasks — Flash Sale LP fixes, PDP business rules, loyalty push toggle, Social Proof, listing/PDP keys, try-at-store/TAH analysis, deeplink fixes, Strapi → Home Page stitching, 5xx/payload hardening
Strapi CMS: V3→V4 migration support; App Skin / banner / Home Page configuration
Performance & stability: launch optimization, network/traces/DataDog, lazy-load config; production crashes & live issues; SwiftLint leadership; Rollbar/Firebase monitoring; deeplinks (TAH, User Xclusive); UTM / UserTraits; Swift 5→6; ET / release support

About

Calm ownership. Production bias.

I’m a product-focused iOS engineer who likes owning features end-to-end — clear UX with Design, solid Swift architecture, and a clean path through TestFlight to production. When the product needs it, I also work in Ruby/MAPI and Strapi so mobile, API, and CMS stay aligned.

B.Tech Information Technology, Coimbatore Institute of Technology (CGPA 9.03). Based in Chennai.
