foreword
When I was in college, I was majoring in computer science, and I worked on a project with my teacher for a year and a half. Sometimes, do you have such an idea to build your own website, but you have not put it into action.
In 2022, I finally put it into action. It took three months to learn and sell now, and stayed up all night to build a small website in PHP, but I didn't stick to it in the follow-up.
After switching from the telecommunications industry to the Internet industry, the idea of making an application of my own became more and more urgent, so I started to invest in the camp of Android App development this year.
This year, I made 4 Android App applications intermittently, one company application, and three self-owned applications. From the early study to the follow-up practice, many things need to be explored by yourself
Based on salary and treatment, with development as the ultimate goal, we must seek the best development in places with high salaries!
