Work Experience
Senior Front-end React Developer
AXA XL
- Led a team of front-end engineers to create a responsive internal UI library using StoryBook, React, Redux, and custom MUI components which would later be used across the company for new applications, and provided onboarding support.
- Led the front-end initiative on three brand new internal to React applications used company-wide.
- Helped vet and onboard new front-end engineers for multiple different projects that I led the architecture for.
- Worked closely with product owners and designers to create pixel-perfect designs to meet company standards.
Front-end Developer

- Wrote high coverage unit tests with tools like Jest and Enzyme, and preformed refactor on existing code to increase readability, maintainability, and efficiency.
- Worked with and reviewed code from other senior-level engineers and helped with the QA process and debugging code when needed.
- Worked on four different repositories (two dealt with front-end React code and the other two handled back-end Python work).

Research Assistant
Ryerson University
- Worked closely with Dr. Cherie Ding and a PhD student to create a Twitter-based recommender system. I specifically focused on the gathering, storing, and the application of Twitter data.
- Created a program that pulled 3.5 million tweets from new users every day, with zero upkeep (using Scala). The data was stored in a database for later use, and it would automatically be updated as tweets were pulled in.
- Automatized the system and error-tested it to make sure the data was unique and supported.
Experience
Terrarium
1. Stay alive as long as possible (get as many steps).
2. Eat food.
3. Do not fall into the water.
Using a simple neural net and genetic programming, I created a bot that plays the game and gets better at it. By the 1,000th generation, you can see that the algorithm has a general increase in lifetime, a.k.a. steps.
To run it, unzip the file, install the required Python libraries, and run genetic_terrarium.py.
It's recommended that you run human_terrarium first to understand the game.
Geneural.net
This algorithm was created using Python and Numpy. No additional machine learning libraries were used as the algorithm was created from scratch by me.
My team and I won third place in RUHacks, a coding competition, for this project.
I specifically designed the entire genetic algorithm, code, and concept.
