Since around 2000 until 2017, the speaker had been developing software for ECUs of air conditioners and cluster meters at a supplier company in the automotive industry. In there, he had faced many of the typical problems in the software development such as quality issues and resource problems. Those experiences made him think more about the importance of testing and its tools, and motivated him to join Vector Japan in 2017. He continues to seek for the best solution to help software developers in the world.
