What I'm looking for

I am seeking a role that allows me to leverage my fraud prevention and team leadership experience in a product management/operations role.

I am Certified in Payments and Fraud Prevention and trained in AI Product Management. I am passionate about blending fraud expertise with innovative technology to protect company revenue.

Proven ability to lead cross-functional initiatives from concept to delivery, translating operational pain points into scalable product solutions. Adept at stakeholder communication, vendor management, and leveraging data to drive product strategy. Passionate about building secure, user-centric experiences at the intersection of fraud prevention and product innovation.

Experienced in leading high-impact product initiatives in the trust & safety and eCommerce space. Partnered with Product, Engineering, Data Science, and Compliance to design and implement fraud prevention systems, including the launch of an Appeasement Abuse Team and Fraud Bot—preventing $4M+ in annual losses at Instacart.

Owned complex fraud workflows and project execution, aligning strategy with organizational KPIs and directly influencing $7M+ annually in cost savings. Skilled in developing scalable processes, evaluating fraud signals, and using data insights to inform roadmap decisions and optimize user safety.

Previously at TikTok (ByteDance), I led a 29-person team to implement strategies that saved over $8M+ annually through chargeback reduction and risk mitigation. As a Senior Fraud Analyst at Instacart, I sharpened my expertise in AML compliance and product development, ensuring seamless experiences for legitimate users while deterring fraud.

Currently, I contribute to fraud investigations, leveraging behavioral analysis to enhance security in a dynamic tech environment.

My global experience, spanning Botswana, South Africa, the UK, Hong Kong, and the US, has equipped me to lead diverse teams and foster collaboration across cultures, driving impactful results in every role.

I am eager to contribute these skills to your organization and look forward to hearing from you soon.
