I'm Bradley, hello.

Bradley Mackey

Full Stack iOS Developer
BSc Computer Science

Computer Science 2019 graduate from Durham University (BSc) with first class honours. In my final year project, I created a deep learning based answering system for the mobile quiz gameshow HQ Trivia; Apple WWDC18 Scholarship Winner; intermediate/senior level full stack iOS developer (primarily Node.js).

I'm currently working in a startup environment and enjoy the facing the challenges that they bring from a technical standpoint. There are a huge number of problems that still need solving for the future and I hope I can help with just a few of them. I'm thinking of starting some kind of blog soon to document my exploration into new iOS technologies (how cool are SwiftUI and Combine!) as well as modern server programming with Rust (or anything else that I find interesting).



Quickly Answering Multiple-Choice Questions using Deep Learning

Final year computer science project dissertation. Area of study is performing open-domain question answering on games of HQ Trivia, using deep learning and Google AI Language's BERT to generate answer predictions in real time. This was my first exploration into machine learning and found it extremely interesting; I was able to achieve a result similar to the state of the art in open-domain, multiple-choice question answering.

Treasure Town

A application prototype created for Y Combinator's Startup School 2018. As the technical founder, I developed the entirety of the frontend (iOS) and backend (Kubernetes, Cassandra, Node.js, Elasticsearch, Stripe). Digital Ocean was our backend infrastructure thanks to the Hatch startup program providing us with $30,000 of infrastructure credit. We also made use of Firebase's simple suite of free developer tools.

RSA Playground

My entry for a WWDC18 scholarship. It provides an interactive introduction to RSA Encryption within a Swift Playground. I am very fortunate to have been selected as a 2018 winner! Open source.

Swift Playground

Grapevine

This was a social networking application I created in my free time using iOS and Firebase. It allowed for friends to chat anonymously with each other within an iOS client app. I discontinued this, but all the client code is open source.

Open source on GitHub.

Emoji Sort Playground

My entry for a WWDC17 scholarship. I created an interactive introduction to sorting algorithms within a Swift Playground, using fun emoji characters. While unsuccessful, this was an invaluable Swift learning experience.

Hold the Circle

This is a simple game I created for my Extended Project Qualification (EPQ) while at school (A*). It makes use of SpriteKit and you can download it on the App Store.

Edit: Looks like Apple removed it because it included a small gambling system to unlock new characters? I'll see if I can sort this out.

iOS app, available on the App Store.
