I currently work on the mobile team at BASE1, the crew responsible for building the next generation of enterprise e-commerce mobile solutions. I'm very passionate about software engineering and can often be found working on personal and/or open source projects when I'm not in the office. When I'm away from the computer, you can find me exploring Vancouver Island where I currently reside, climbing, cycling, running, or paddling in the ocean.

Personal Projects

Tex

LIGHTWEIGHT MINIMALIST UNIX TEXT EDITOR

Tex is a minimalist text editor for bash terminals, written in C, with zero dependencies. I started this project after having to write a memory allocator and blockchain in C for a course, and wanted to create something more usable in real world scenarios. Tex features all the typical features one expects from a text editor, with the addition of filetype detection with language based syntax highlighting, and robust searching all in a small open source editor.

ISS Tracker

Cross-platform ISS Tracking & educational app

An app created with Flutter & Dart to track the current location of the International Space Station (ISS), the next time in passes over the user, current crew information, as well as history about its creation, assembly, and some other facts. The app fetches the latest information about the crew and continuous location data for the tracking & next pass features, through one of NASA's API and presents it in an easy-to-digest manner for the user.

RNN Text & Code Generator

Smart text generation using a recurrent neural network

Leveraging the power of Keras and Tensorflow, this script generates text using a recurrent neural network. I designed this to be very flexible, working on any text source, ranging from scraped data, sonnets, a novel, or even code. I've personally trained this network and generated text based on Shakespearan sonnets, Star Wars movie scripts, and the linux kernel with great results.

Realtime collaborative editor that aims to assist writing content in Markdown. From pretty-ing up Github readmes, to writing copy for a JAMstack site, or simply your latest blog post, this project makes it dead simple to spruce up your content. This project was realized using NodeJS for the backend, Redis for in-memory database storage, and ShareJS to facilitate collaborative editing.

Experience

BASE1

Sr Mobile Developer

BASE1 brought me on as a mobile developer to assist in the development of their main client's enterprise Flutter mobile app with over 2.5 million monthly active users. Alongside shipping major features, supporting production, meeting with stakeholders, and the other various responsibilities involved with developing the mobile product and services, I also delved into developing and extending the Hybris (SAP cloud commerce) back-end along with the myriad of micro services used. This gave me valuable enterprise infrastructure and server development experience that I continue to expand upon.

Swift Ventures Inc.

Mobile Developer

I was contracted by Swift Ventures to assist in the development of an upcoming mobile app (Name protected by NDA). Originally brought on to upgrade and port the app to a web app, they were quickly impressed and kept me on to assist with the development of the cross platform mobile application. I was responsible for everything from programming a web socket handler to implement push notifications and real time data streaming to the app, writing services to interact with Firebase and AWS server, to fine tuning and implementing UI elements. Working remotely, I took advantage of Slack, weekly standup meetings, and the agile development paradigm to ensure consistent and efficient communication with the rest of the team.

GADEC

MACEWAN UNIVERSITY GAME DEVELOPMENT CLUB

I worked with various teams consisting of writers, producers, designers, composers, artists, and fellow developers to bring a randomly selected constraint and theme to life, in a video game format (although we did occasionaly create board games). Working in bi-weekly sprints, we would come together to form an idea with what's provided, and produce a demo or MVP of sorts to present to the other teams. The following semester of each year consisted of taking the team's favourite project, further fleshing it out with new features, art, QA, and general polish all around. The respective games each year were then presented and demoed at the Press A to Start conference/convention.

Sept 2018 - January 2020
