Experience

Interactive Form Editor

A React-based web application in which I had to integrate the existing APIs from the older AmigoCloud implementation, allowing the users to define their data schema, visibility, and requirement conditions based on the information being filled out by their clients.

Dynamic Form Solution

A React-based application that is used in our web application and mobile devices, allowing the users to visualize the forms they've created using the Form Editor. The main goal was to have a single work solution in multiple places—a preview for our online Form Editor without the user saving schema changes, an interactive web UI for collecting new data, and a tool for gathering new information on the mobile devices.

I defined the communication protocol between the forms and clients, regardless of the preview, web, or mobile solution, implemented each field type, and introduced a digital signing solution.

Online Map Editor

A React-based application that helps AmigoCloud's clients create interactive maps based on the previously collected information, allowing them to share the resulting maps internally—within their company—or externally.
