Employment
Experience
- Hugo for RGPhttps://www.hugobyrgp.com/
Working with one other front-end developer for most of the project, I developed the front end and API back end for a flagship React application for a billion-dollar company. The app had three different front ends for different user types and a shared component library for a common look and feel.
- Cisco Defense Orchestratorhttps://www.cisco.com/c/en/us/products/security/defense-orchestrator/index.html
I developed a security-focused Angular application for Cisco's high profile product that manages networking devices, executes scripts across hundreds of machines, and pushes configuration settings on demand by network administrators.
- Facebook Marketplace
I developed many of the major parts of Facebook Marketplace prior to it being re-acquired by the Facebook corporation. Working closely with designers and analytics experts, as a solo developer, I revamped the entire post flow leading to a 4x increase in conversions.
- JUICE Programhttps://www.dropbox.com/sh/w7aeovehwpnsikq/AAA1qElX_24eBcWdH6G8prS0a?dl=0

I created the main brand website for Hello Kitty and her friends as well as the accompanying eCommerce platform. Inventory information was conveyed and managed through a custom-built JavaScript spreadsheet program similar to Google spreadsheets that interfaced with mainframe applications that drive worldwide product management.
