I have been working on information technology for over 15 years, mostly I am engaged in products development, and I enjoy the experience of developing products from zero to one. Since I have experienced in many technical fields, including embedded system, android, ios, advertisement delivery engine and web application development, I can clarify the problem even for the products integrated various departments, which reduces the unnecessary consumption (communication cost) for the company, and ensure the product is on its process as the schedule planned. Due to the desire for new technology, I still follow and evaluate some cases as a technical team member. New technology and system are adopted to reduce the risk caused by human being, which can improve the quality and reliability of software, and promote the efficiency of team cooperation. As far as I am concerned, leadership can be achieved only when the leader cooperates with the team members and provides the direction for them, for example, a project will pass to the members when I truly master the technology, this is a way to avoid the delay of the project schedule and increase their confidence.
