Media Flashcards

A friend and I began taking American Sign Language classes through Visually Speaking and North Seattle College in 2020. We wanted flashcards to help us practice on our own, but had a hard time finding an existing sloution that did everything we wanted.
I created the Media Flashcards project to solve that problem. Features:

  • Practice Mode
  • Search Mode
  • Option to see sign side, English side, or mixed in Practice Mode
  • Sign side can contain static images, gifs, or videos
The repo is currently private because it contains videos of our instructor demonstrating signs in the classes we paid for.

Hogwarts Battle

My husband and I love to play the Hogwarts Battle deck building board game. However, one of our biggest issues with the game is the number of things players need to keep up with at all times, often resulting in missed steps and overall incorrect game play.

As we're both Software Engineers and were both looking for a project to practice a new programming language in, we decided to try building it ourselves. We are developing 2 versions in parallel: mine in Python, his in Rust. We pair program in both languages and review each other's code, but put most of our energy into developing the game in our respective languages.

The repo is currently private due to copyright concerns. Demo coming soon!

POUND Setlist Generator

I started teaching a fitness format called POUND in 2020. In this format, instructors create a setlist of tracks. POUND provides setlist templates with different difficulties, lengths, track levels, and track types. There are so many track options to insert into each slot, that I get overwhelmed when trying to create or change up a setlist.

To solve this, my setlist generator will build a setlsit for me using only songs I know. It is currently a command-line tool that allows me to choose a setlist difficulty, length, and version and returns a full setlist. I can choose to replace a track with a different one and include arm tracks.

I have many more ideas in store for this project. In the mean time, you can view my progress on GitHub.

TEALS

TEALS, or Tecnology Education and Literacy in Schools, is a Microsoft-sponsored program that pairs volunteers with programming experience with high schools around the country, and Canada. Most schools still do not have any kind of CS or technology progrqams, but of the schools that do, they often do not have access to teachers who are familiar with the material, so teachers end up teaching CS classes with no more knowledge than the students.


TEALS provides several benefits:

  • Schools can implement successful CS programs with the help of knowledgable volunteers
  • Students get direct access to volunteers that are part of the industry that can answer questions about the material and careers alike
  • Over several years with the program, classroom teachers can learn the material alongside students and take over teaching when they are comfortable with it

I have volunteered with TEALS since 2017, taking a minor break for the 2020-2021 school year. I have taught remotely at Walla Walla High School for most of those years, except for one in which I taught at Tonasket High School.


I grew up with a family of teachers, so education has alwasy been a very important part of my life. I found from a young age that I enjoyed teaching: my earliest teaching memory is from when I was about 5 years old teaching my cousin to read using my Explode the Code phonics books. I never considered teaching as a career, but once I found TEALS, I realized it was the one thing I had been missing! I get to be a software engineer AND a teacher! How could it get better than this?

Mentorship

Mentorship is an important part of my professional life. It helps me stay motivated in my job and reminds me why I love doing what I do. Even in my much needed year off from TEALS, I pretty quickly realized I missed working with students. I joined Mentors in Tech, or MinT, where I mentored 2 students on a monthly schedule -- a much more manageable time commitment for me that year. I have had several great mentors in my career so far, starting with my step-dad (or bonus-dad, as we liked to say) Abel Wang, who introduced me to CS. I was lucky to have someone around to help me with homework, answer my questions, and engage and encourage me in CS, so I am always happy to be that person for someone else.
