About Harsha G.

I\'ve spent 10+ years shipping iOS apps used by millions — from BLE-connected electric vehicle platforms to international checkout systems processing secure payments across multiple countries. At Walmart Global Tech, I own features end-to-end across the international checkout platform (Mexico & Canada), working across iOS and the Node.js Orchestration Layer. Recent highlights: launched the Walmart Protection Plan (projected $3.8M annual profit lift), leading payment authorization features addressing $9.9M CAD in annual revenue leakage, and resolving the top iOS payment error during a major platform migration — all with zero production incidents on delivered features. Before Walmart, I built mutual fund and SIP modules at PhonePe (India\'s largest UPI platform), a BLE-powered EV management app (NemoLife) at CognitiveClouds, and health/medical apps like SmartBP (millions of App Store downloads) at CodeCraft Technologies. Each role sharpened a different edge: secure payment flows, Bluetooth hardware integration, Core Data pipelines, real-time audio/video, and cross-platform API design. What I bring to a team: deep iOS platform expertise paired with product thinking and the ability to debug distributed systems that span frontend, orchestration, and backend services. I don\'t just write Swift — I design systems that scale, own them from PRD through production, and ship experiences that move business metrics. Exploring senior and staff-level mobile engineering opportunities where I can drive architectural decisions and multiply team impact. Let\'s talk: h••••••••@gmail.com
