About Me

I'm a seasoned iOS developer with 3 years of experience crafting robust, scalable applications. I specialize in Swift and SwiftUI, complemented by practical UIKit knowledge. My core competencies include architecting applications using MVVM and The Composable Architecture (TCA), developing reusable SDKs, optimizing application performance, and streamlining development workflows through GitHub Actions, scripting, and Fastlane.

Technical Expertise

Programming & Frameworks

Swift: Strong proficiency in Swift 5 and Swift 6, including modern language features
SwiftUI: Building responsive UIs with complex state management and custom animations
UIKit: Working knowledge of UIKit fundamentals and SwiftUI integration patterns
Tuist: Feeling for modularization and scalability

Architecture & Design Patterns

The Composable Architecture (TCA): 1 year and a half with TCA, implementing scalable, testable features with precise state management, also with TDD practice
MVVM: Designing decoupled, maintainable application layers with reactive bindings

SDK Development

XCFrameworks: Designing, building, and distributing modular, ABI stable, binary frameworks compatible across multiple platforms
API Design: Creating intuitive, well-documented public interfaces for third-party integration
Versioning Strategy: Implementing semantic versioning and managing backward compatibility

DevOps & Automation

CI/CD Pipeline Optimization: Configuring GitHub Actions workflows for efficient build, test, and deployment processes
Fastlane: Automating App Store deployments, certificate management, and testing procedures
Scripting: Creating custom automation tools for development environment setup and maintenance

Performance Optimization

Xcode Instruments: Profiling applications to identify memory leaks, CPU bottlenecks, and rendering issues
Periphery: Implementing dead code analysis to maintain codebase efficiency
SwiftUI Performance: Optimizing rendering cycles and view hierarchies for smooth user experiences

Testing Methodologies

Test-Driven Development: Implementing unit and integration tests to ensure code reliability
Swift Testing: Writing clear, better and more expressive tests with less code
XCTest Framework: Writing effective test suites for business logic and UI components
Mock Objects: Creating testable architecture through dependency injection and protocol mocking
