Saily
https://www.dropbox.com/sh/h10qi33slrbv3zw/AACbqSL-_LDxn6B5gjfsN5Aoa?dl=0Saily is the lovely local marketplace that links you with buyers and sellers around you.
The project started as a side-project and evolved rapidly to become a VC-funded startup. The marketplace had a huge user-base of 500,000 registered users, and a team based out of San Francisco & Beirut.
As Saily's technical co-founder, Dani built version 1 of the iOS app, along with the back-end API and database. The iOS app focused on having a beautiful UI & an engaging user experience, and with added humor here and there, users simply loved it!
Dani then headed the technical operation as the startup's CTO. He laid out the technical roadmap, hired talented engineers, built the core infrastructure, and set up guidelines.
