Experience
- Agent ReVahttps://agentreva.com
A Spring Boot + React + Facebook Messenger API-based application. We developed a virtual assistant chatbot that can recommend homes that best suite your needs using live MLS data. The application's user interface is exclusively accessed through Facebook's Messenger application. We used Google's Dialogflow for NLP capabilities and other technologies to index the massive amount of MLS data needed to make home recommendations.
- Reusable Widgets for Enhanced Customer Engagements
One of my clients required custom code written on multiple branded websites. The websites were all eCommerce or information that led to third-party eCommerce websites. The goal of the functionality was to improve customer engagement on their direct-to-consumer websites and fulfill industry-specific compliance requirements.
It was important that some of the websites be updated in collaboration with existing web administration teams. These teams were technical enough to make some HTML/CSS/JavaScript changes but not enough to develop custom experiences using JavaScript SDKs.
The solution I came up with was to develop reusable and smart engagement widgets. These widgets would be easily extensible using simple key/value HTML attributes as CSS for style.
The code was written using React+WebPack, where all the complex JavaScript and back-end code is invoked.
Thus, the website would get a simple JavaScript file to include and a number of CSS classes to apply to their webpages to display the React module. Adding complex functionality was as easy as using CSS.
