For Jonah, delivering a project's requirements is non-negotiable. Fortified by his time as a full-stack developer, product lead, and engineering lead, tethering to the users' needs and psyche is his most powerful tool and the driving force of his delivery guarantee. Jonah believes that for a project to be successful, the objective must drive the development rather than having development set limitations on the requirements.

Experience
Track Insight
On this project, I theorized, designed, and created a platform to enhance the ability for Elite Athletes to track complex training sessions, recovery, and rehabilitation workouts through a detailed interface and return useful feedback on improvements, slumps, and other occurrences.
This platform is built by athletes for athletes with the goal of providing details answers to curiosity towards improvements and declines by comparing time frames of data and reporting on differences.
This was built with the Ionic Hybrid framework and the full Firebase toolset. A Flask API is used to analyze and report on data. The full design was created by myself and co-founded using Sketch.
The app is in the works of being distributed among Team Canada's track and field athletes.

Decathlon Scoring Calculator
This is an entirely native app on both iOS and Android. Basically, it is a decathlon scoring calculator and is used to leverage a point table algorithm to match athletic performances to scores based on available decathlon measurement provided by the IAAF.
FratBase
Here, I built natively for iOS and Android, FratBase: a communication suite geared towards advancing the efficiency and reliability of intra-fraternity communication.
I developed for the fraternity council at Concordia University, the app gears to centralize information for fraternity chapters to allow for ease of communication through features such as a calendar, real-time chat, announcements section, member/role management, and more.
It was built with Swift 4 and Java, the app is entirely native and powered by Firebase toolset. The full design was created by me in Sketch
