I got into copywriting when I needed extra money while working as a TEFL English teacher. I have now grown my own small buiness into a multi-employee operation.
Prior to completely changing the direction of my life, I had a job in IT. I am comfortable writing about pretty much any subject in relation to technology, software, or even fintech. I have no problem being a general writer as well.
