Hire U.S.-Based SharePoint Developers and Microsoft 365 Experts

When a SharePoint migration stalls, governance goes unowned, or a build needs more hands than your in-house team can spare, you hire SharePoint developers who plug into your environment rather than a vendor who studies it for a month first. i3solutions is a U.S.-based Microsoft systems integrator and SharePoint development company that has done this work since 1997. We embed vetted, senior, U.S.-based developers, architects, and Microsoft integration consultants with your team in as little as one to two weeks. The usual first step is a SharePoint Risk and Roadmap Assessment that hands you a sequenced plan, whether you run it yourself or have us embed a developer to execute it.

Build Faster with Microsoft-Centric SharePoint Developers You Can Trust

Whether you’re under pressure to retire legacy SharePoint systems, build SharePoint digital workplace solutions, or roll out enterprise-wide document management and HR workflows, the right development talent makes all the difference. i3solutions provides U.S.-based SharePoint developers, SharePoint architects, and Microsoft-certified consultants who can embed quickly and start delivering value from day one.

With nearly three decades of experience in SharePoint application development and Microsoft 365 integration, we understand how to make the platform work for complex enterprise needs. Our developers do more than write code. They’re SharePoint integration specialists who understand governance, SharePoint security and compliance, performance, and the real-world needs of mid-to-large organizations. Whether you’re hiring a single SharePoint software engineer or scaling a full SharePoint development team, we align with your roadmap and back every engagement with the full strength of our Microsoft system integration services.
