Contributions & Reflections
As the software team leader, I led a team of 13 members in the development of the project. I was responsible for designing the overall system architecture, managing tasks, and solving the most critical issues. Additionally, I performed code reviews, controlled the development flow, and maintained project documents. I also worked closely with the hardware and design teams and had frequent communication with them.
This was the most impressive and time-consuming project of my college life. I worked on it for over three years and saw significant improvements each year. Through this project, I not only gained technical skills but also leadership experience. I learned how much value others can bring to a project and had a great time working with many talented people. If you are interested in the project, please consider giving us a star on GitHub!
