It's good you updated the Github comment, but you should also consider explicitly stating your affiliation when relevant when commenting on Hacker News in the future.

If you had done in this case, it would have immediately cleared up encoderer's questions about your Github comment.

It's not doing much for your reputation (or that of your employer) that you still haven't clarified whether you are the engineer or not - even after deliberately referring to yourself in the third person and being called out for it.
