At On The Fuze, I deliver HubSpot CMS and CRM projects for U.S. B2B clients. I led a BrandTrust form migration, resolving QA issues across dozens of forms with HubSpot API scripts in Python.

For SBI Growth, I audited a site rebuilt across several themes, scoped 892 pages for retention, and delivered a 780-hour migration estimate. I also built custom HubSpot modules and created a development playbook that reduced bug rates by 30%.
