What I'm looking for

I’m available for 6–12 month project engagements.

At Grid Dynamics, I’m leading two platform initiatives for PetSmart’s Consumer Mobile app: removing embedded API credentials through a TypeScript BFF and migrating the iOS codebase to Swift 6 strict concurrency. I’ve also routed Contentful CMS integrations through the BFF and added preview support so merchandising can validate campaigns in-app before publication.

Across project engagements for Google, Domino’s, Venmo, and Walmart, I’ve shipped iOS security, payments, rewards, and accessibility features. At Banco Azteca, I delivered CoDi QR payments and built a remittance feature that enabled international payouts in under five minutes.
