Experienced software developer with a focus on Apple technologies

I am passionate about mobile platforms and web languages, particularly Swift and C++, as well as Android and JavaScript. I am a diligent developer who applies SOLID principles and has extensive experience working with server-based communication apps. I also have a strong affinity for SwiftUI applications and possess excellent knowledge of the full iOS SDK stack, including third-party libraries managed via Swift Package Manager.

• Leading the development of multiple internal packages using Swift Package Manager, some of which have already been converted for use with Skip tools.
• Leading the development of multiple SwiftUI applications utilizing various communication protocols and APIs such as gRPC with Protobuf, MQTT, WebSockets, and REST APIs, ensuring high-performance and scalable solutions.
• Collaborating with stakeholders to conceptualize and refine new features, while aligning technical capabilities with business needs.
• Working closely with Project Managers to plan and prioritize sprint tickets, while maintaining an agile workflow and meeting delivery timelines.
• Supervising and mentoring a team of two iOS developers, conducting performance reviews and setting clear objectives to foster professional growth.
• Implementing robust app features by adhering to MVVM and MV architectural design patterns, ensuring maintainability, clean coding practices and applying SOLID principles.
• Developing the initial driver for the company’s latest hardware using Swift and C++, leveraging DriverKit frameworks and Swift’s Unsafe functions
• Ensuring all projects are maintained under continuous integration (XCTest and XCUITest) and continuous delivery pipelines (GitLab, Fastlane, and TestFlight), streamlining development and deployment processes.
• Maintaining jobs in our CI pipeline using Fastlane and GitLab to build, test, and distribute both iOS and Android apps.

In my dissertation, I developed an app in Objective-C to demonstrate how the iOS operating system and its framework ecosystem work together. The project made use of various iPhone features (GPS, alarm, camera, etc.). Users could create rules between these features, allowing them to build custom automations as they wished.
