Montane Ranch

https://www.montaneranch.com/app#/home
The community application is a Ruby on Rails-based platform facilitating communication and engagement within closed communities, such as residential areas and ranches. As a full-stack developer, I played a key role in building and delivering the application's various features and functionalities.

On the front end, I utilized React to create an intuitive and user-friendly interface for residents to access important community-related tasks, such as park and event schedules, houses and apartments for sale, and other community-related information. This allowed residents to stay informed about community happenings and activities in real time from any device.

On the back end, I used Ruby on Rails to develop a comprehensive suite of features that enabled residents to track, schedule, and book events, activities, and amenities within their community. This included a robust event tracking system that allowed residents to view upcoming events and RSVP, as well as a scheduling and booking system that enabled them to reserve community resources, sports facilities, and more.

My contributions as a full-stack developer were instrumental in bringing these features to life, and I'm proud to have been a part of such a valuable project.
