focused support
I occasionally take on scoped remote HubSpot CMS and frontend work when the problem is a good fit for my background.
- HubSpot CMS themes, templates, and reusable modules
- HubSpot UI extensions with React and TypeScript
- HubSpot API integrations, serverless functions, and internal tools
- Frontend implementation for focused product or marketing workflows
Best fit: defined build, migration, module, integration, or technical support work for remote-friendly teams where senior HubSpot CMS execution matters more than a large delivery team.
