## What I'm looking for

I’m looking to scale my impact as an iOS architect.

## About

```text
At PayPal, I use Swift and UIKit to build new parts of the app and maintain older Objective-C code. I also write unit and automation tests and work with RESTful services.

At WHOOP, I developed app features using SwiftUI and UIKit, and worked with Combine, unit tests, and UI tests.

At Klever, I developed and maintained applications with SwiftUI, Combine, and iOS 15. I implemented gRPC services using Protocol Buffers and adopted TCA in several modules.

Across my iOS work, I’ve contributed to apps at Venmo, SKY Brasil, and other organizations, including features, legacy-code maintenance, testing, and app performance improvements. I’m looking to scale my impact as an iOS architect.
