Is it correct to use a semicolon or a comma in this sentence?
I worked on quite a few projects and websites since 2009; some of them are shown in the portfolio above.
I absolutely think it is. The rule of thumb for semi-colon use is when you have two stand-alone clauses (i.e. where you have a full stop at the end), and want to connect them.
Semi-colons shouldn't be used with conjunctions (and/or/but etc), but your sentence doesn't have this feature.
You would also be fine to use 2 clauses, but particularly for readability, the semi-colon helps the reader understand there is a connection between the two clauses.
The Oatmeal has some quite lovely tips which you may find helpful, amusing and interesting.
Using semicolon is art, if you use in wrong part in sentence then it going to make sentence grammatically mistake.
Semi colon is used to distinguish the sentence from the paragraph.
Example I went to shopping and bought; Watches, bags, dresses.
So it defines I went to shopping and bought watches. I went to shopping and bought bags.
The word start often the semicolon should always start with capital letter.
