Resumey.Pro began as a side project, when my co-founder was looking for a job. We realized we were having issues designing a resume as we have to pick a template first and then stick to it. The ability to just write content and then have the flexibility to make changes for the design was something we were looking for but couldn't find on the internet. Markdown is quite powerful for writing so we combined the two ideas and created a tool for ourselves. Eventually, when we realised it's useful we made it public for others to use and productized it. We also launched on Product Hunt where we got a lot of useful feedback.
