# ResortPass Engineering

> ResortPass is a marketplace for booking day passes, cabanas, spa access and day rooms at luxury hotels and resorts. How the ResortPass engineering team builds and ships the product behind day access to more than 2,700 hotels: architecture, delivery, and hard-won lessons.

Articles are long-form notes from ResortPass engineers on how the platform is built. Launches are the monthly record of what the team shipped for guests and hotel partners.

## Articles

- [Discovery as a Domain](https://www.resortpass.com/engineering/articles/discovery-as-a-domain): Search, browse, merchandising and recommendations kept doing the same work over the same data, so we gave discovery its own language and an engine to run it.
- [Why ResortPass Chose a Native iOS App](https://www.resortpass.com/engineering/articles/why-resortpass-chose-a-native-ios-app): We are rebuilding the ResortPass iOS app in Swift and SwiftUI after years on Flutter. Here is why native won, what it costs, and how agents are helping us rebuild it.
- [How We Ship: The Daily Release Train](https://www.resortpass.com/engineering/articles/how-we-ship-the-daily-release-train): We replaced three environment branches and a cascade bot with one main branch and a daily train that soaks each commit on staging for a day before production.
- [Retrofitting Language Into Our Stack](https://www.resortpass.com/engineering/articles/retrofitting-language-into-our-stack): We planned to use an off-the-shelf Rails library for translations. A few weeks in we backed out and began resolving language at the API boundary instead.
- [Why ResortPass and What We are Building](https://www.resortpass.com/engineering/articles/why-resortpass-and-what-we-are-building): People already love our experiences, and most of the decisions that will define our product, technology, and culture are still ahead of us. That combination is why I came.
