Our stack and tools

We will build a new React-based frontend, currently we use Sencha ExtJS 3.4 and 6.5 for Frontend. For our redesign we will be applying Brad Frost's Atomic Design Methodology. The backend consists of PHP7 applications using Zend Framework 2 and Doctrine 2, backed by multi-tenant MySQL/MariaDB databases.

Our toolset includes Slack, JIRA, Bitbucket, Confluence and Google for Business. We use Jenkins as a continuous integration server.


About us

Delivering the best possible healthcare to patients worldwide requires an efficient research process that drives innovation in healthcare. Currently, 85% of resources spent on medical research do not contribute to patient health. At Castor we are creating user-friendly technology that solves these issues. Founded by an MD PhD, we understand that researchers want technology to work for them, not against them.


Our goal is to ensure the world’s research data becomes reusable and machine-readable so that we can leverage the power of AI to help us solve the biggest healthcare challenges. To be successful, we need to continuously improve and grow our product. We believe we can accomplish this with a healthy, happy, world-class team that is looking to make an impact.
