Why Hiring SharePoint Framework Engineers Is Challenging

Industry data suggests that 40–50% of internal SharePoint customization projects stall due to a lack of specialized JavaScript and React skills required for the modern SharePoint Framework (SPFx) model.

Why JavaScript: The SharePoint Framework relies exclusively on client-side development using TypeScript and React. Engineers must master the SPFx toolchain—including Yeoman generators, Gulp build tasks, and strict package versioning—alongside standard web technologies to build performant web parts and extensions.

Staffing speed: Smartbrain.io delivers shortlisted JavaScript engineers with verified SharePoint Framework Development experience in 48 hours, with project kickoff in 5 business days — compared to the 8-week industry average for hiring developers with Microsoft 365 platform expertise.
