WORK PROJECTS
Migration of React Native CI from Jenkins to Github
I led migration of React Native CI pipelines from Jenkins to GitHub Actions, reducing build times by 40% using caching techniques and optimised Docker processes. This was a really cool project to work on as the benefits were felt immediately by engineers working on the project.
Sky Bet Games - React Native Rebuild
I played instrumental part in React Native rebuild of legacy Sky Bet Games application hosted on AWS ECS. From its inception I worked on the project to improve performance, reduce bundle size and improve the developer experience. This was an awesome project to work on as it was a complete rewrite of the app and I was able to use my React Native knowledge to help the team build a better product for customers.
Safer Gambling Tooling
I led the rebuild of a high-traffic Safer Gambling tool triggered on every game launch using AWS Lambda, ElastiCache, and Aurora. Successfully load tested to handle 6,000 requests per second, with flawless performance post-deployment
LEARNING & DEVELOPMENT PROJECTS
AI Chatbot
A python CLI that uses AWS Lex to create a chatbot that can answer questions about a Mars Mission. See images in the readme for more details but it uses AI to query files uploaded to S3 and answer questions about the mission. This was a really fun project to work on as it was my first time using AWS Lex and I was able to use my Python skills to create a chatbot that can answer questions about a Mars Mission.
Avec Chien (With Dog)
A noddy node app to hit the Strava API and count the miles done with my dog. Planned to move this to AWS Lambda eventually. For anyone interested shes on about 500km at the min :O
React Punk
A React Native app that is a Daft Punk soundboard. It uses the Expo Audio API to play sounds and has a simple UI to control the playback. This was a fun project to work on as it allowed me to experiment with audio in React Native.
Dream Blend
A React Native app that uses Google's Vision API to identify objects in images and uses DeepAi to generate a new image based on the identified objects. This was my first foray into AI and it was a really fun project to work on as it allowed me to experiment with AI in a mobile app.
