    How We Connect Your Systems

    We build inside your existing tech stack rather than asking you to replace it. Most engagements connect through APIs already exposed by your platforms, and where systems don't talk to each other natively, we build the integration layer, whether that's a REST or GraphQL API, a MuleSoft-based connection, or custom API integration work like what we've shipped on Salesforce engagements. On Salesforce specifically, our default is to extend what you have with Apex, LWC, and Flow rather than migrate you off it.
