The person behind JobOfferMaster
I applied to 100+ jobs. Then I built this.
I'm Charles Guo — engineer, dad, and a person who knows exactly how much work sits between finding a role and getting ready for the interview. Because I did it more than a hundred times myself.
Every application meant the same dance: find the posting, copy the details into a spreadsheet, retype my address, rewrite the cover letter, lose track of where I was. The pieces were everywhere. So I built the thing I wished existed — one calm place where the posting, the application, and the interview prep all live together.
JobOfferMaster isn't a faceless platform. It's a small, hand-built tool from someone who sat on your side of the screen — and who still answers the support emails himself.
