Looking for a job

Roberto Hernandez

@robertohernandez

I’m an iOS Software Engineer delivering native Swift apps at scale with Clean Architecture and SwiftUI.

What I'm looking for

I’m looking for an iOS role where I can own end-to-end delivery, build modular Swift architectures (Clean Architecture + MVVM), and partner closely with product and engineering to ship performant features for high-traffic apps.

I’m an iOS Software Engineer specializing in native Swift applications at scale. I focus on delivering performant, reliable, and maintainable features through end-to-end ownership and tight cross-functional collaboration.

At Tapcart Inc., I drove modular architecture adoption using Clean Architecture + MVVM across major app surfaces for a commerce platform serving 1,500+ merchants and millions of users. I rebuilt Cart and checkout experiences with Shopify Cart API and Checkout Sheet API, using Combine and Swift Concurrency to eliminate technical debt and improve checkout reliability and conversion rates.

I’ve also shipped user-focused capabilities like Wishlist features and engineered a cross-module communication layer for merchant-configurable Custom Blocks—bridging legacy and modern flows without requiring native app releases. Earlier, as a part-time iOS Software Engineer at HoopStop Mobile LLC, I built a production-ready Swift/SwiftUI iOS app with MapKit and Firebase, contributing dynamic messaging and Firebase Cloud Messaging-driven push notifications.
