I advocate for the needs of customers by first gathering and understanding their requirements. I ensure these requirements are met through thorough validation. I also take into account the usage context, such as right-hand driving in India and left-hand driving in the US, to tailor the user interface accordingly. I rigorously check performance and conduct user surveys to gather feedback, making adjustments based on the results. I meet with vendors to understand their usage and perform real-time testing in cars to ensure that features work as intended. My focus on UI/UX allows me to provide a seamless and intuitive experience. Through these steps, I effectively meet customer needs.
