请帮忙修改英语自我简介

我很高兴在这里做自我介绍。我的名字是…，我出生在重庆，27岁。毕业于重庆师范大学，信息管理专业。毕业后在浙江省从事康明斯发动机售后管理工作3年。之后在重庆康明斯发动机公司装配车间，从事发动机装配及发动机调试工作。
现在我已经掌握了几种技能：1发动机装配原理，2发动机性能调试，3发动机故障判断。这些是作为发动机销售工作的基础。我希望能加入贵公司，希望能给我一个机会，非常感谢。
I'm glad to be here to introduce myselfe.my name is ****. I was born in chongqing, 27years old. I graduated from chongqing normal university, majored in information management. After graduation in cummins engine service management work three years in zhejiang province. After join chongqing cummins engine company assembly workshop, present job is engine assembly and engine testing.
Now I have mastered some skills: 1 engine assembly principle, 2 engine performance testing. 3 engine breakdown judgment. These are as engine sales work foundation. I hope I can join your company, the hope can give me a chance. Thank you very much.

不错不错，还知道杭州银鹏。。。你是上海康明斯还是北京康明斯，还是其他代理商的？？？报个名撒。。。说不定还是熟人也

如果是到外企参加面试，不用介绍你出生，不用介绍你年龄。只要说你的工作经历和学历就可以了。如果对方还没有你的简历，去的时候可以带上至少三份，万一面试官不止两个。注意一些细节问题，走的时候可以要求握手。可以先说你的名字，然后说很高兴介绍自己，你想想别人怎么说你就别怎么说，没有哪个考官想重复听一样形式的自我介绍。至于后边的错误：i worked in cummins engine company in zhejiang province for 3 years after graduation, doing service management stuff. then i move to chongqing and worked in the assembly workshop in cummins engine company.
now i believe i have mastered certain skills, like engine assembly principle, engine performance testing. engine breakdown judgment. which i think are the bases of engine sales.
i hope i can be a member of your company and i think my involvement will be rewarding for both you and me. thank you very much,
只是一些简单的修改，如果你有什么具体问题还可以百度hi我。希望对你有用。

没什么好修改的，very good,对了，最后一句话中的“I hope（加一个to）I can join（把your换成this更好）company，就这些
