A startup providing a new way of buying and selling real estate. This Vue.js application helps streamline the process.

Drop Shipping Automation Tool

This project's goal was to cut the time it takes a drop shipper to filter and select winning products from several hours to several seconds.

The user would provide a keyword to find products relating to and the tool would scrape the product inventory site and extract all potentially suitable products, filtering the results based on specific criteria, such as sales, reviews, and views.

The results would then be added to a Google Sheet for the user to browse.

Automated SMS Outreach Tool

This client wanted to re-engage with customers after their order was complete in order to try and get them to make a second order.

The problem was solved with a tool which would extract a set of users based on pre-defined criteria (e.g., 30 days after purchase) from their existing point-of-sales system.

It would then send each customer an SMS message offering them a discount or notifying them of a new service etc.

The tool was written with Node.js and MySQL.
The Vidswap platform allows sports teams to capture and analyze their team's performance.

It is used by sports teams across the world including high school, college, and professional levels and caters specifically to more than ten sports.

I am involved with building the front-end web application that the players, coaches, and loggers use on a daily basis. I have worked on numerous features that enable the process from end to end.

• Custom Gantt chart component
• Player and event position data visualization with D3.js
• Drag-n-drop lineup creator
• Playbook builder
• Integration of features closely related to videos, including overlay drawing, timeline tagging, and video clipping

The application is built with the Ext JS framework.
