01 About me

Engineering software businesses can rely on.

I’m a software engineer with over eight years of experience building products end-to-end — from database design and REST APIs to the React interfaces people use every day. I specialise in designing and deploying scalable web applications and microservices in the cloud, and in the unglamorous but critical work of making many systems talk to each other reliably.

Today I’m an Integration Developer at Nimo Industries in Melbourne, building the APIs and third-party integrations behind a digital lending platform — CRMs such as HubSpot and Zoho, and payment and banking services such as Westpac QuickStream, PayWay and Banking Circle. Before that I helped rebuild an in-house money-transfer platform at Forex Sport, led the build of an NDIS care-management CRM, automated cloud infrastructure for a UK credit-management platform, and spent nearly four years turning healthcare data into insight at Cotiviti.

I do my best work in collaborative, Agile teams where I can own problems end-to-end, communicate clearly with stakeholders and keep learning. I hold a Master of Information Systems from Holmes Institute, Melbourne.
