Portfolio

I'm an engineer interested in computer vision, iOS development and overall making useful software that benefits people's lives. When I work on a project, the goal is to match the function with a clean and easy to use interface design. I'm currently  living and working in Tokyo, Japan. If I'm not at a Starbucks on my laptop I'm either learning Japanese, reading books on self-improvement, or finding new useful frameworks to add to my apps. If you're looking for freelance work, please send me a message.

Rezistr app started as a university engineering final project and evolved into a full app for other engineers or electricians to use. With the variety of iPhone camera hardware it is a real challenge to tune image processing algorithms to fit in every situation, but I continue to explore new ways to improve the app and decided to release it in its current state to help those who find use in it.

A little background 

My very first introduction to coding came from web design using HTML. I started building websites in a text editor and creating banners and buttons in photoshop for video game websites or discussion boards with my friends. From the age of about 14 my interest grew and I started picking apart my favorite video games to see how they worked and made changes here and there coding modified versions of games that I could play online on servers I hosted. Even earlier than that I was creating 3D environments to play in using game engine development software Hammer World Editor for the Source Engine. The levels I created were originally for my friends and I to enjoy, but now have over one million subscriptions combined.

In high school I was part of a group that worked on my school's website, and went on to win a competition to create a website for my local animal shelter. It wasn't until college that I started to take an interest in app design where I chose as my senior project to create a resistor identification app. The project was successful and I went on to complete my degree in Electrical Engineering. Post-college, life took me in a different direction where my first professional job was in electrical design for buildings using Autocad and Revit. After about a year in this field it was apparent that it wasn't for me, and I decided to return to my roots in programming with app design which encompassed many of the skills I already developed over the years. I took some time off and built a more user friendly version of my resistor project, Rezistr, for the app store as well as my Japanese kana learning app, Japaneasy. In-between I would learn how to use various frameworks and API's I found useful such as Google Firebase, Facebook SDK, and others.
