Questions we get asked a lot.

In our work, integration means all things API. We integrate systems via API, create APIs, extend APIs, and architect and build API integration layers, based on our clients’ needs.

Core10 is an integration partner for ICE Mortgage Technology Encompass, Plaid, Constellation Digital Partners, and we are also a participant in the Jack Henry & Associates, Inc. Vendor Integration Program. In addition, we have integrated with many other systems on behalf of our clients, and we add new APIs to our toolkit all the time.

We provide partner-specific training where available, and design and deploy our own internal training paths where needed. Our developers also participate in mentor/mentee relationships where they can share their expertise with younger developers or ask for assistance from more experienced ones.

Our primary tech stack includes a back-end written in C#, Java, Python, or Node that interfaces with a modern front-end written in Angular, React, or VueJS.
