Skills

Python

My love for working with Python my entire career stems from its versatility and development speed. There’s a time and place for careful planning, but at a certain point, code needs to hit the editor and Python is excellent for quick iteration that can be later refined. I’ve used most data science/mathematics packages and frameworks like Django and Flask.

Curiosity, learning, action oriented

I could not be where I am now without a drive to learn and better myself. There is still plenty of growth in my career but I truly believe there is nothing I can’t do as I’ll learn and overcome any challenge.

New languages, frameworks, problems, I promise I’ll rise to the challenge. I truly have a bias towards action and need to solve problems as I come across them.

Communication

I pride myself on being able to explain myself clearly, convey ideas, and updating/staying updated about my current projects.

Personal projects

• AlreadyFriends
• Intelligently uses self-reported relationship data to predict pairs of strangers to be used for a “speedfriending” system by cataloguing users and their relationships within a group.
• Automatically generates a list of matches for the current roster of attendees and logging said matches
• Admins can additionally update user relationships based on user submitted data
• OnRead
• Allows users to take their Facebook Messenger data and use it for interesting insights.
• Word usage frequency, sentence structure, response time, and time of arrival for messages used as behavior metrics to identify conversation partners.
• Web app allows users to input a text sample and receive the program's best guess at an author.
• WilsonBot
• Uses current voice call participants and their gamer tags to produce several “balanced” teams for casual esports matches
• Allow users to share their links to competitive game trackers, like OP.GG or Tracker.GG
• This data can then be used with a list of participating users to create "balanced" teams within Discord such that opposing teams have an even mix of higher and lower skilled members
