Kenya

Message

At Stonefield Company Limited, I delivered the CITAM Kisumu Business Conference & Expo and Lake Region Trade Expo, generating 58 leads and KES 4M in qualified pipeline on KES 58,000 spend. The campaigns converted KES 1.3M within a month.

I lead Stonefield's marketing functions across brand, digital marketing, events, CRM and customer feedback. I track spending and lead-to-invoiced-revenue conversion against ROMI, CPL and CAC.

I rebuilt the customer survey with NPS classification and escalation triage, and ran Customer Service Week to strengthen CSAT, NPS and feedback closure. I also led the CRM selection and rollout of Odoo CRM, Helpdesk and Surveys alongside SAMS for Sales.

Previously, I managed B2B Google and Meta Ads campaigns at Odiwuor Digital Limited, managing USD 15,000+ in monthly ad spend and achieving 100,000+ conversions with 15% lower CAC. I built GA4 dashboards for real-time ROI attribution and budget decisions.
