Hi there. I'm jack. Currently working on a resume project.

I major in CS. When it comes to 2019 I went work in a SaaS company which provide CRMs. And 2023 everything changed. We all know gpt came out. So there are many layoffs there. However it is not hard and didn't affect me but it changed my mind. In 2025 I decided to give up my PM job and go for a start_up. Not a SaaS company but a small company provide industry level-AI implement solutions. I suddenly found I can develop almost everything with claude code.(Only build process.I leart cpp py and js in the university) So I finally go for my start up. Thanks there for you guys. I believe in 3 yrs later start_up will be a more popular trend.
