As a senior developer on the Coles Pay project, I designed and implemented the login and identity orchestration system powering Australia’s largest retail network’s digital wallet solution. My primary focus was handling the complex migration of legacy users from flypay.com.au while building robust identity management with multi-factor authentication.
