Haider Aljawasim developed core features and infrastructure for SanaaTeam/Novix and TheChance101/MENA-mobile, focusing on scalable architecture, robust data layers, and cohesive UI systems. He implemented end-to-end navigation, onboarding, and localization, integrating Kotlin, Jetpack Compose, and Retrofit to deliver responsive, testable workflows. His work included building a DataStore-backed user preferences system, modularizing design system components, and establishing backend API contracts for media and catalog features. By emphasizing test-driven development, dependency injection, and maintainable code organization, Haider enabled rapid feature delivery, improved internationalization readiness, and ensured reliable user experiences across mobile and backend platforms in production environments.

October 2025 performance highlights: Delivered end-to-end navigation and refactor for Dukan/Shelf flows; added paging for product listings; enhanced Dukan UI loading states and shelf creation UX; expanded backend Dukan Catalog API with category filtering and detail retrieval, plus data migration safety; completed core refactors and quality improvements to boost maintainability and reliability.

September 2025 focused on establishing a solid Dukan foundation, delivering core architecture, media workflows, localization readiness, and backend scaffolding, while strengthening quality and maintainability. Mobile delivery established core architecture and base infrastructure, image cropping UI/flow, localization groundwork, packaging/name refactors, Dukan image upload and data model, and DI/testing improvements. Backend progress delivered shelf domain model and endpoints, image upload core with API stability, entity/name fixes, data seeding, and code quality improvements. These efforts enable faster feature delivery, more reliable media handling, better internationalization readiness, and stronger API contracts with improved testability.

April 2025 - PlanMate: Laid a solid authentication and session-management foundation, delivering secure, test-covered features and enabling faster future delivery. Implemented AuthenticationModule scaffolding and AuthenticationRepositoryImpl with refactors and unit tests; introduced SessionDataSource, SessionMapper binding in AppModule, and session entity improvements with tests. Added an MD5 hashing extension for strings and enabled SPA login to return UserEntity, along with InvalidCredentialsException for clearer error handling. Expanded test coverage (SessionRepositoryImpl, SessionMapper, LoginUseCase, LoadSessionUseCase) and fixed mocks; resolved merge conflicts with develop and cleaned up unused imports. Tech stack demonstrated: Kotlin/Java, DI (AppModule), repository/data-source patterns, unit testing, and robust error handling.
