Here at OFX I am a fullstack engineer overseeing both the front end and back end.
We have a Typescript tech stack, React in the front end and Node JS in the back end. We use Vite for the build, open API for API first development and AWS CDK in a monorepo based structure. We also use AWS services extensively such as Dynamo, Lambda and SQS. OFX is based on a serverless structure.
OFX is an application which allows making payments easier than ever. You can make a payment, deposit or withdrawal in Australia and it will settle instantly. You can also make low cost, same day payments to 180+ other countries.
