Recommendations

Many past colleagues have recommended me on LinkedIn. Some highlights:

Jeffery is a brilliant web developer that challenges conventional thinking and raises the bar for the team around him…

A mutual colleague once told me that Jeff is “the best front-end developer in Hong Kong”, and after having worked with him for over two years, I’m inclined to agree.
