Persona

Specialization9/10

The developer demonstrates a strong and consistent focus on native iOS development, with multiple projects in Objective-C and Swift targeting Apple's ecosystem.

Technology Adoption7/10

Shows a clear progression from older Objective-C projects ('peregrine', 'firefly') to using Swift ('peaches'), indicating an ability to adapt to modern language standards within their primary domain.

Project Documentation4/10

Repositories include brief descriptions but generally lack detailed READMEs, setup instructions, or usage examples, suggesting they are primarily for personal use or small, internal teams.

Skills

Objective-C8.5/10

Demonstrated deep experience through multiple non-trivial applications such as 'peregrine' and 'epic26' for UCDMC, and the 'firefly' BLE project.

iOS Development8/10

The entire profile is centered around building native iOS applications, covering areas from medical software to hardware integration and 3D graphics tests.

Swift6/10

Authored the 'peaches' project, showing practical application of Swift for iOS development, though the body of work is smaller compared to Objective-C.

Hardware Integration (BLE)7/10

The 'firefly' project is explicitly for a Bluetooth Low Energy wearable, indicating specific and valuable skills in connecting mobile apps to external hardware.

C4/10

Used C for the 'ship-spinner' SceneKit test application. This suggests foundational knowledge but lacks evidence of complex, production-level C programming.

HTML3/10

While HTML is the most frequent language by repository count, the projects appear to be simple wrappers or web views for native apps rather than complex, standalone web applications.

Growth

1.Create a new, more complex application using Swift and modern iOS frameworks (e.g., SwiftUI, Combine) to showcase up-to-date skills and balance the Objective-C focus of the portfolio.

2.Enhance top repositories like 'firefly' and 'peregrine' with detailed README.md files. Explain the project's purpose, architecture, and challenges to better communicate expertise to viewers.

3.Leverage the unique experience in medical and BLE applications by writing a technical blog post or creating a well-documented sample project that teaches others a specific aspect of this domain.

4.Add GitHub Topics to all repositories to improve their discoverability and clearly categorize the technologies used in each project.
