I joined the distribution team at MainStem. When I joined there was no technology, not even a website for the company. Over the years I built out a RESTful JSON web based API with a React JS front-end to help serve our customers and suppliers in a complicated niche supply chain. We've grown the business to several hundred customers and have processed tens of millions (USD) in transactions.
