Project History
Copyright Bank Pty Ltd

I set up the entire infrastructure of the blockchain nodes and the CI/CD pipelines to build and deploy back-end and front-end applications in the Kubernetes cluster. Additionally, I set up a private blockchain network using NEM catapult.
StoreConnect: Time well spent
https://getstoreconnect.comThis project is an eCommerce PAAS platform built on Salesforce and Ruby on Rails. I predominantly acted in the role of a senior engineer while working closely with clients and the core engineering team. Together we built custom integrations and add new functionality to the core platform.
DayByDay Pty Ltd
https://daybyday.ioThis product was a blockchain-based insurance application that uses NEM smart assets to record assets mainly used to ease insurance claims by showing timestamps in the blockchain network. I was the primary developer and tech lead, managing a team of 4-5 developers.
Leo Cussen Center for Law - Spree Store
https://store.leocussen.edu.auServed as a contractor for three months. The majority of my work involved fixing existing bugs on the platform. I also updated their legacy-looking application to give it a more modern look in two weeks using Bootstrap 3.
