During my work, I was mainly in charge of developing database and network software. Meanwhile, because of my excellent ability of designing software, I was sent to participate in IMS, which is a big network management system. My duties have ranged from writing modules to testing system. With the heavy working load, I have accumulated rich experience and developed a strong capacity for independent research. Furthermore, working experience, which gives me a solid platform to prepare for my career pursuit, does great help to further my understanding of software systems and improves my professional skills, therefore, my future goal is becoming much clearer.

我想表达的是从毕业后到现在我的工作状况，现在我还在这个公司工作呢，而IMS只是我工作时参加的一个项目，现在结束了，I was mainly in charge 这个was对吗？同时I was sent to 对吗/ which is a big network management system.是不是应该是which was啊？
My duties have ranged from对吗，还有后面的时态，我总觉得有问题

During my work, I was mainly in charge of developing database and network software.

I was mainly in charge 这个用was，I was sent to 这个用was，which is a big network management system这个用is，这是阐述一个客观事实，不需要用过去时。My duties have ranged from 这个不用加have。

没有什么问题～很好

The main responsibility of my work is to manage the development of the database and network software. I was also sent to participate in the work of IM
