Mondale Felix

Architected scalable, enterprise-level iOS applications, designing backend data models and API contracts that supported a 30% reduction in development time. Established CI/CD pipelines with Jenkins and GitHub Actions, implementing XCUITest automation to achieve 85% test coverage for backend interactions. Optimized app performance by 40% through network call refactoring and efficient caching mechanisms. Integrated RESTful APIs using the Combine framework for reactive data flow with AWS backend services. Mentored junior developers on backend best practices via code reviews and set team coding standards. Collaborated with design to implement performant SwiftUI UI components rendering complex backend data.
