I was hired to develop a back office system for a local company. It currently has 30,000 users, about 25% of whom use the site daily.
I developed and am in the process of improving something I call a 'naive sensorimotor inference engine.' I intend to improve it to the point that is generally useful on any non-time-series data in any deterministic, fully observable environment.
I've produced a windows automation tool. Without any programming anyone can create macros that specific triggers that run autonomously.
To learn Ruby on Rails I built a custom customer relationship management system for John Johnson and his mortgage company. The custom design facilitates collaboration between loan officers, underwriters, managers, outside realestate agents and even barrowers on loans as they go through the completion process.
To gain an intuitive understanding of blockchain technology I assisted Wil Bown in designing a prediction market that caters to fast paced transactions between machine learning models running on the miners' machines. Though this product was designed it was only partially implemented due to lack of funding.
My first project with Ruby on Rails was CouplesBudget which I created and used. It's a simple "envelope" budgeting system for two.
I wanted to create an android app. Years ago I had created one using the android app inventor from google (now owned by MIT), but more recently I wanted to make one with web languages so I recreated my original minimalist Jar's Budget app.
As an exercise in jquery and ajax I created a small stock market game which pulls from real world stock data from a database without refreshing the whole page - welcome to the internet of 1998!
