I have often written for money. The topics were frequently financial: commodities, company shares, industries, spread betting techniques, forex, tax, market indices, and general news. For leisure, I have written extensively of conspiracy theories, UFOs, and environmental matters, and I can provide the URLs for these articles. I have used WordPress a great deal.
I have been paid for a number of copy editing tasks. I completed a course in proofreading through the Writers Bureau where my work was independently assessed.
I know Excel to macro level and taught it to 16/17 year-old students at one of the best secondary schools in Thailand. I know Word very well. I used to work as an MS Access developer. I taught English as a foreign language for more than five years.
