During April 2025, Ahmad developed foundational architecture and data-processing features for the Food-Change-Mood and Task-Manager repositories. He established layered project scaffolding, implemented robust CSV parsing, and introduced dependency injection with Koin to enable flexible, testable business logic in Kotlin. Ahmad refactored meal suggestion flows, optimized data loading, and improved UI integration, supporting maintainable and scalable code. In Task-Manager, he set up Gradle-based project bootstrapping, integrated code coverage tooling, and enhanced CI reliability using GitHub Actions. His work focused on clean code organization, comprehensive unit testing, and efficient error handling, resulting in higher quality, maintainable systems with clear business value.
