Jason Lawrence's work portfolio from 2005-2014 includes descriptions of four projects he developed: 1) DigiFlix, a video streaming website allowing users to share and view videos founded in 2012. 2) Happy Time, a joke submission app letting users submit jokes and vote on others' jokes with prizes for top votes. 3) Channels, a social media aggregator collecting Twitter, YouTube, and Instagram updates on set topics. 4) Reporting systems showing popular videos, revenue, user messages, and clicks for DigiFlix and Channels, and a validation dashboard for Happy Time jokes.
