My start was working for a company in a developing country who were struggling to find a way to escape spreadsheet hell. I was a business analyst but decided it surely couldn’t be that hard to program and create some kind of system myself! A month or 2 studying “Head First PHP” and I started work on a system to help the company manage their import, export and container yard operations. A few months later I was done. To my knowledge (and absolute horror), they are still using it to this day.
I’m back in Australia 3 years ago, happily working as a senior dev, but reading some of the posts here really brings back memories of the excitement I would get when those “ah ha!” moments would strike during those initial first months.
