I create and explore at the intersection of technology, design, and the human experience. As a developer, designer, and lifelong learner, I’m drawn to building things—digital or otherwise—that are thoughtful, useful, and grounded in curiosity about how we live, grow, and connect.
Projects
2024-now
Fully developed as part of my independent venture, Sajama Apps, this iOS app was built in SwiftUI and published to the App Store. It cultivates the practice of self-observation—bringing awareness to emotions, body sensations, and thoughts. Designed to encourage brief pauses throughout the day, it helps users step out of automatic patterns and into a more grounded, present experience.

XCode
The app was built from scratch using SwiftUI, following a clean MVVM architecture to keep the code modular and testable. All logic and state management are custom-implemented, with Core Data used for persistence and local notifications supporting both scheduled and randomized reminders. Where SwiftUI lacks flexibility, I interfaced with UIKit to refine specific views and behaviors. The architecture includes lightweight service classes to abstract storage and support swapping out the data layer in the future. Designed with long-term maintainability in mind, the structure supports scaling and feature expansion without sacrificing simplicity. No third-party dependencies were used.

Design Patterns
Built as part of a course project focused on data structures, object-oriented design, and design patterns. The tool was designed with modularity and readability in mind, using principles like separation of concerns and encapsulation. Unit tests were written to validate core functionality and ensure code reliability. Emphasis was placed on structuring clean, maintainable code that could be extended for different analysis tasks.

Modular Design
Completed as part of an exam project emphasizing the ability to work within a predefined architecture. Implemented method logic across multiple interrelated classes, including file readers, parsers, and data models. Strengthened skills in interpreting existing design patterns, understanding object collaboration, and writing effective unit tests for individual components. The project required careful attention to maintaining design integrity while contributing reliable, testable code to a larger system.

Unit Testing
Built as part of a foundational software development course, this project emphasized real-world problem solving within a predefined architecture. The application loads expenses from multiple .txt files, storing them in a dictionary for efficient access and manipulation. Users can add, deduct, update, and sort expenses, as well as export filtered results to a file. Focus was placed on core logic implementation, working within constraints, and writing maintainable code.
