Not a hack, but something I'm proud of: I built/launched an entire transactional site: signup/login/purchase membership while walking the Camino de Santiago in Spain, in 2017, for a small event (swing dance event). Was supposed to spend the two months prior to going there working on it, but because of delays in planning etc. I didn't really get started until the week right before, which meant I had to haul my old MBP 2015 on the walk. So basically, I trekked something like 18-20 miles a day lugging that thing (and the charger), then spending mornings/evenings in the little hostels (more like barracks) writing code (most had wifi, thankfully), then the next 4-6 hours thinking through how to design/build every little piece, then find a cafe with wifi to implement some of that in 2 hours, then walk another 4-ish hours. Then write more code. Surprisingly, there were almost no bugs at all, since I'd have to iron out every single thing during the walk (what else are you going to do walking through middle-of-nowhere Spain, which is all farm land, anyway?). In the end everything worked! Paypal integration worked! Hundreds of people signed up and bought membership on the system! Oh, and this was my first project of this sort, and I was the solo designer/developer on it. I also had to design our logo, branding, and T-shirt as well. (Stack: Meteor, DO)
