Experienced iOS developer delivering scalable mobile apps with strong problem-solving and team leadership.
MexicoWhat I'm looking for
I am an experienced iOS developer with a background building and shipping mobile apps from prototype to App Store release. I have worked across startups and agencies, leading mobile teams and managing timelines while collaborating with designers and backend developers.
I specialize in Swift, Objective-C, iOS frameworks (SwiftUI, MVVM, VIPER) and app architecture, and I routinely implement unit tests, CI workflows, and package management to improve code quality and reuse. I have contributed to projects for clients such as Walmart and WeWork and built product-ready apps including chat and e-commerce solutions.
As a hands-on engineer I manage feature requirements, debug and fix issues, create lab flags and experiments, and validate pull requests. I also have cross-platform experience with Kotlin/Android, RESTful APIs, GraphQL fragments, and web stacks when integrating mobile apps with backend services.
I am punctual, customer-focused and a strong team player who values clean, reusable components and continuous learning. I seek roles where I can drive mobile engineering best practices and help deliver high-quality user experiences.
