Santiago Bernaldo De Quirós

- Most spoken communication was conducted in English due to working within an international team.

- Contributed to a TDD-driven migration from a legacy architecture to a multi-endpoint architecture, applying SOLID principles across the codebase.

- Took ownership of the App Store release process, managing the full Git Flow from development to main branch and ensuring stable production releases.

- Migrated several UIKit views to SwiftUI, preserving existing business logic while introducing new SwiftUI view models and improved state management.

- Pioneered the adoption of ViewInspector to enable unit and UI testing of SwiftUI views, significantly improving testability.

- Increased unit test coverage to 25%, being one of the main contributors to TDD and testing strategy, especially within the Networking and Use Cases layers.

- Improved test coverage across SwiftUI view models and views, leveraging test doubles, mocks, and ViewInspector.

- Worked across two squads: one product-focused and another dedicated to B2B clients, collaborating with cross-functional teams.

- CI/CD pipelines using Bitrise for automated testing, building, and App Store deployments.

Acted as Crash Dispatcher for two sprints, analyzing crashes, identifying root causes, and reporting actionable issues in JIRA.

- Fixed critical bugs and delivered new features on time, contributing to overall app stability and product evolution.

Designed and developed a full-featured iOS app for remote workers using Swift, SwiftUI, Firebase, and modern architecture patterns. The app includes Apple/Google/email/faceid/touchid authentication, account deletion, guest mode, and over 20 functional screens. Core features include location-based check-ins, nearby spot discovery, route launching via Google Maps, work session logging, profiles with session history, and viewing sessions from followed users. Social features such as follow/block/comment are fully implemented with privacy-aware filtering across search and maps. Built using Test-Driven Development (~300 tests, 80% initial coverage), async/await, and a clean Composition pattern for dependency injection. Architecture is modular, MVVM-based, and designed for scalability and testing. Fully aligned with App Store privacy guidelines, with proper handling of location permissions, manual check-ins, and user-controlled visibility. A professional-grade app built over months of focused work, showcasing clean code, robust privacy, and thoughtful user experience design.

As a student in Caio & Mike's program, I experienced exponential growth as a developer. The program offers deep dives into advanced iOS programming topics such as modular software design for building robust systems and apps, test-driven development, and the application of SOLID principles and best software practices.
