I’m an experienced Senior Product Manager with 10+ years leading end-to-end product strategy, design, and technical execution across global digital platforms. I focus on owning complex systems, integrating multiple platforms, and improving operational workflows and user experiences for millions of users. I’m passionate about building scalable, reliable, user-focused products in fast-paced, remote-first environments.

At Oxfam International, I own and lead multiple global digital platforms supporting fundraising, advocacy, and operational workflows across Africa, MENA, and Latin America. I lead the full product lifecycle—defining roadmaps and vision, translating requirements into PRDs and technical specifications, coordinating discovery/prototyping with a user-centered, data-informed approach, and managing integration points so data flows reliably. Key wins include leading the end-to-end rebuild of 22 Oxfam websites, integrating Fundraise Up to improve donation funnels and international payment reliability, digitizing Annual Reports (2024 & 2025) into immersive Shorthand experiences, and standardizing petition platform UX to reduce drop-offs and increase completion rates.

Before that, I strengthened my product and delivery foundation as a Web Developer & UI/UX Designer at Oxfam International, redesigning petitions pages for UX and accessibility and developing interactive campaign pages that increased engagement and donations. Earlier, I handled end-to-end web solutions and technical + UX strategy at The Boma Hotel / Kenya Red Cross, and I managed MVP scope, user journeys, and information architecture at Plan A-Z limited. I also co-founded Halisi Mosaic Collection, where I led product development and online sales strategy—bringing an operator’s mindset to product execution, collaboration, and measurable outcomes.
