To bring Certainty’s app to life, we were asked to collaborate with another software company to bring our blockchain technology and front-end development expertise to the table. The app needed to have an adaptable interface, with the ability to dynamically change looks, functionality, and fields depending on the web API demands. For this project, we needed to collaborate closely between development teams to keep communication clear and processes effective.


At Flexsible, we’ve created a collaborative environment that we offer to our clients as well. By hiring engineers on a contract basis, our clients can have high-end professionals for any project they need to bring to life. In this case, Certainty already had back-end developers and project managers in place, so we were able to provide front-end developers on-demand to interact with their Web API and our project manager to organize both boards. Beyond engineers, we were able to set up a CI/CD pipeline to ensure the entire process ran smoothly with no hiccups.


We’re changing the way people think of sharing information.
