Hey community — I’m looking to connect with a developer who has hands-on experience building custom cards using HubSpot’s CRM UI Extensions framework (React-based). We’re redesigning our Deal page and have three custom cards fully spec’d and ready to build: - A dynamic **Stage Workspace card** with tier-conditional checklist rendering, append-only narrative fields, file upload modals, and hard gate logic - A **Program Builder tab** that surfaces program selections and ACV calculation output from existing deal properties - A **Document Library tab** with template access and a submission workflow including date validation Full documentation, an HTML mockup, and a property list are ready to hand off on day one. This is a build engagement, not a discovery engagement. **What I’m looking for:** - Demonstrated experience with HubSpot CRM UI Extensions specifically — not just HubSpot admin or general API work - Comfort working from a detailed spec without hand-holding - Available for an estimated 8–10 day build If you’ve built custom cards on the HubSpot developer platform and are open to contract work, I’d love to hear from you. Drop a comment or send me a DM. Thank you! ---

5-star rating in HubSpot Solutions Directory: [HubSpot Marketplace](https://ecosystem.hubspot.com/marketplace/solutions/trooinbound-com) Hi @BWoodard12, this is exactly the kind of advanced HubSpot work we handle regularly. We’ve built multiple custom CRM UI Extensions (React-based), including dynamic deal-stage workspaces, gated workflows, and custom cards that tightly align with business logic, so your use case fits right in our wheelhouse. We’re a HubSpot Certified Diamond Partner with 10+ years of experience and a team of 150+ certified experts working deeply across CRM architecture, UI extensions, and automation. We’re very comfortable working off detailed specs and jumping straight into build mode without hand-holding. Your scope, especially the Stage Workspace logic, Program Builder calculations, and Document Library workflows, is something we can execute cleanly within your 8–10 day timeline. Happy to review your documentation and share relevant examples of similar custom card builds. Would you be open to a quick 15–20 min call to align on access, timelines, and any edge cases before kickoff? ---
