App In The Air
A US travel app with 6M+ users, by the company's count. I joined to build the web side, then led the frontend and the corporate B2B portal.
App In The Air is a travel app for people who fly a lot. The main product was mobile, and I was hired as a frontend developer. First I rewrote the website in React, then built flight booking in the browser from scratch.
After that came hotels, a white-label widget for airlines and a corporate portal for business travel. The appintheair.com website and the webview screens inside the app were mine too. I hired frontend developers myself: job posting, technical interview, a take-home task with a code review call, then onboarding.
We shipped a release every three weeks: two weeks of development, one of testing. Every release branch got its own staging environment, errors went to Sentry and analytics to GA4.
