I am an aspiring computer science student and know about languages such as Python and C99. Also, I use several popular code editors such as ST3 and VSCode which makes me confident enough to write on different themes, plugins etc.
My English proficiency level (Reading and Writing) is on par with a native English speaker. This means that I can write almost any article for a nominal fee. Plus, I read several books per month which makes me more confident in my repertoire.
Being confident in my ability to quickly research on a specific topic and spot grammatical errors/blunders, I can and will try to deliver a consistent and a coherent article .
