A comprehensive management web application built specifically for leasing businesses. The platform gives users the tools to manage their product inventory, sales, and expenditures efficiently. With Lease-it, users can easily view important statistics such as top-selling products, remaining payments from customers, and individual payment records for each customer.

As the sole developer overseeing the building of this application, I utilized a combination of Ruby on Rails and Vue to create a robust and user-friendly platform that could effectively meet the needs of leasing businesses of all sizes. I started the project from scratch, leveraging my front- and back-end development expertise to deliver a powerful and comprehensive solution.

Lease-it has been a game changer for leasing businesses looking to streamline operations and maximize productivity. As the developer managing the building of this innovative platform, I am proud to have contributed to such a valuable tool for the industry.

Montane Ranch

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.

The inventory management system allows users to track their machinery, including its current location, condition, and availability for rental or sale. They can easily create invoices, manage payments, and generate reports to track their business performance.

In addition to the inventory management system, the application provides users with a powerful CRM tool to manage their leads, contacts, and campaigns. Users can track customer interactions, create and manage campaigns, and generate reports to measure their marketing efforts.

Overall, this web application provides a one-stop solution for businesses to manage their inventory, customer relationships, and online presence, all in one easy-to-use platform.
