Tiago Antunes

Leading iOS development on a large-scale modular architecture (80+ independent frameworks) for a major European classified ads marketplace serving millions of users across multiple brands and countries. Architected and delivered complex features using MVVM-C pattern, Coordinator-based navigation, and modern Swift concurrency (async/await, Combine), following Clean Architecture and Clean Code principles with strict separation of business logic from UI. Leveraged AI-powered development tools including Sourcery for automated mock generation, SwiftGen for code generation from resources, and Claude Code for accelerated feature development and architectural refactoring. Managed feature development using trunk-based development with remote feature toggles (Firebase, AppsConfig), enabling progressive rollouts and AI-driven A/B testing experiments across multiple markets. Maintained exceptional code quality through comprehensive unit testing (XCTest), snapshot testing, automated code generation pipelines, and strict linting/formatting standards (SwiftLint, SwiftFormat) integrated into CI/CD workflows.

Contributed to build system automation using custom dependency management (XcodeGen, SPM), Fastlane CI/CD pipelines, and AI-assisted developer tooling improvements. Implemented full accessibility support (VoiceOver, Switch Control) and internationalization for multiple European locales, ensuring inclusive user experience. Collaborated with cross-functional teams in an agile environment using Gerrit for code review, JIRA for project management, and Backstage for service orchestration.

Led architectural changes to integrate a new Store Intelligence module using artificial intelligence, deep learning, and product recognition to maximize sales and profitability for brands and retailers. Developed features using Swift, UIKit, and SwiftUI for universal iOS/iPadOS application, implementing VIPER architecture to achieve robust separation between business modules aligned with business needs. Maintained high code quality standards through comprehensive unit testing with XCTest framework, ensuring application functionality and reliability.

Developed new internal mobile solution using modern iOS technologies and patterns including Swift, SwiftUI, MVVM architecture, and XCTest for unit testing. Maintained close contact with different business units, responsible for meeting their needs by reviewing and evaluating technical feasibility of requirements. Managed projects using GitLab, Confluence, JIRA, and Jenkins for version control, documentation, issue tracking, and continuous integration.
