Supreme Golf is a tee time marketplace: it aggregates availability and pricing from courses it does not own and presents them to golfers as one searchable, bookable list. It covers more than a million tee times across 13,000 golf courses in 41 countries. CodigoDelSur refactored roughly 90% of its iOS and Android apps and worked on the platform for close to four years.
A tee time marketplace aggregates inventory nobody owns. Thirteen thousand courses in forty-one countries means thirteen thousand sources of availability and pricing, each with its own booking rules, all presented to a golfer as one list that is searchable, bookable and correctly priced. On top sits everything a golfer expects: GPS on the course, scorekeeping, reviews, price alerts. The apps CodigoDelSur inherited could not keep growing in that shape.
CodigoDelSur refactored roughly 90% of both applications, rebuilding them around the search and booking flow while keeping the product in the stores throughout. The work covered tee time search across the aggregated inventory, booking and payments through Stripe and Spreedly, GPS and scorekeeping, reviews and price alerts. Pipelines on CircleCI and Fastlane let a refactor that size ship in small, reversible increments. Stack: Swift, Kotlin, Ruby on Rails, Firebase, Stripe.
Roughly 90% of both mobile apps were refactored without taking the product out of the stores, across close to four years of continuous engagement from 2019 to 2023. The platform covers more than 1 million tee times across 13,000 courses in 41 countries, with search, booking, payments, GPS and scorekeeping delivered on iOS and Android.
