An introduction for new company position

Hi, my name is Evan.

I'm new in XXX.
This year I just came back from St. Lucia, in the Caribbean sea.  I worked there as an ICT project assistant. This has been one of the most impressive experience in my life. If you have been there, you must know how beautiful it is on the St. Lucia's beach.

Before the poistion in St. Lucia, I worked in a startup company as a website back-end developer, where I've developed a web reader website.

I love movies, basketball and table games.

Nice to meet you!

[Basically good, but you may want to emphasize your work experience more and not dwell on your time sitting on the beach.]
