Product Engineering mindset
Collaborating across engineering, product and UX to translate user needs into durable mobile experiences.
iOS Engineer
I build native iOS products at the intersection of mobile engineering, AI-assisted development, architecture and product thinking. My work blends Swift, SwiftUI, GraphQL, observability, tooling and human-in-the-loop agent experimentation.
Profile
About Me
Hello, I'm Oscar, a Software Engineer from Chile with over 10 years of experience building scalable digital products, currently focused on iOS engineering. I work on production mobile systems, UIKit to SwiftUI modernization, GraphQL/Apollo integrations, observability, architecture, and tooling that helps teams move with more confidence. I am especially interested in the new shape of engineering work: how strong developers use AI agents, specifications, product context and human judgment to build better software.

What I Do
Scalable architecture & systems thinking
Designing maintainable iOS systems, guiding UIKit to SwiftUI migrations, and integrating GraphQL/Apollo, REST and observability in production.
AI-enabled engineering
Building with AI tools and coding agents as part of the development process, from specifications to implementation review.
Current Edge
iOS + AI + Product Systems
The strongest engineering work now goes beyond writing clean code. I care about how teams use AI tools, agents, architecture and product judgment to raise the quality and velocity of what they ship.
Mobile systems modernization
Migrating UIKit surfaces into SwiftUI, improving architecture, and keeping production apps maintainable while teams continue shipping.
AI-assisted engineering
Experimenting with coding agents, Claude, Cursor and Codex to turn specs, product context and developer intent into safer implementation loops.
Product-aware execution
Connecting technical choices with user experience, observability, cross-team collaboration and clear technical storytelling.
