What do you think of my site and what can I do to improve it?

Hi!

1.Somewhere you’re introduced as a web designer and other times as web developer. Not a big issue but little confusing.

Second suggestion is to move PORTFOLIO prior to About me. As a potential client I first want to see what you’ve done and maybe later who you are.

3. Try to validate your site. Some errors found (7 on intro page)

First, get rid of the frilly stuff in the left border. It is distracting and adds no value.

“my portfolio of some of my recent work.” A little rewording would help. Avoid repeating words when possible.

“in many different languages and many different web standards and styles.” Two manys is too many, that close together. Using and to connect is okay but two so close making different connections makes for more difficult reading. Try something such as this:
in several languages, using various web standards and styles.

etc…

If you want to be taken seriously, any sites you “develop”, especially your own, will be standards compliant.
