HMI Systems Development – Suzuki (Ongoing)

Platform: Android

Architecture: MVVM (Model-View-ViewModel), MVC (Model-View-Controller)

Design Principles: SOLID patterns for maintainable and scalable code.

Key Contributions:

• SystemUI Development: Implemented the overlay (quick access) panel independently, despite it being a new domain.
• Proof of Concepts (POCs): Explored storage mechanisms, factory reset impacts, and window-type behaviors for the new platform.
• Volume Bar: Developed the volume bar, handling both UI and backend logic.
• Notification Feature: Delivered the notification panel as per OEM requirements, including POCs and implementation.
• Navigation Widget: Created a navigation widget using TaskView, introducing this concept to the project.
• HMI Connectivity: Worked as a full-stack developer, implementing ConnectionManager for connectivity features.
• Bug Reduction: Significantly reduced system bugs through proactive analysis and fixes.Collaboration: Served as the Single Point of Contact (SPOC) for connectivity, collaborating across teams to streamline development efforts.

HMI Systems Development – RNM (Renault Nissan Mitsubishi)

Platform: Linux

Programming Language: C++

Tools/Technologies: CGI Studio

Architecture & Principles: OOP, SOLID design principles

Key Contributions:

• Reusable C++ Libraries: Developed core libraries for HMI applications, including speed restriction, keyboard, status bar, and launch bar, promoting code reusability and maintainability.
• Common UI Modules: Designed and implemented reusable UI modules across multiple applications, ensuring consistency and scalability.
• Design Principles: Applied Object-Oriented Programming (OOP) principles and followed SOLID design principles for a modular and maintainable codebase.
• Performance Optimization: Leveraged design patterns, memory management techniques, and performance improvements to optimize system efficiency.
• Cross-Team Collaboration: Conducted impact analysis and collaborated with various teams to seamlessly integrate common libraries across applications.
• HMI Interface Development: Created intuitive and visually appealing HMI interfaces using CGI Studio.
• Documentation: Authored detailed documentation, including design specifications, API references, and integration guides, to support future development and inter-team collaboration.
