I've led Trust & Safety operations at TikTok across Sub-Saharan Africa and EMEA, managing 65+ analysts and moderation workflows handling 1,200+ cases daily. My work supported the identification and removal of 700+ harmful content items each day.

I reduced online abuse exposure from 67% to 11% at TikTok and lowered moderation error from 42% to 19% through targeted policy enforcement, quality initiatives, and coaching. At Samasource, I supervised 35+ analysts and reduced decision error rates from 36.8% to 11.2% through root-cause analysis and calibration.

At Yubo, I investigate online harms involving CSAM, child exploitation, grooming, fraud, impersonation, identity security, scams, and coordinated abuse. I work with product, policy, and engineering teams to close safety gaps, improve workflows, and escalate high-risk incidents appropriately.

I'm also experienced in AI-generated content review, human-in-the-loop moderation, safety policy enforcement, SQL, Tableau, reporting, and analyst development. I bring regional expertise across SSA and EMEA and have delivered safety training and awareness programs reaching 5,000+ users.
