CRM architecture

Zoho CRM was selected as the primary CRM platform, with structures for Jobs / Teams and Talents, and a talent pipeline that mirrors how recruiters actually work.

AI talent matching

A semantic matching architecture was designed so candidates could be matched to jobs by meaning rather than exact keywords. Tens of thousands of talent profiles and jobs were considered within the matching architecture, and relevance could then be reranked using additional business criteria.

Power BI dashboards provided visibility into recruitment performance and operational metrics.

I also participated in the organization's migration from Google Workspace to Microsoft 365, together with the associated domain and DNS infrastructure changes.
