What I'm looking for

I’m looking to lead or build scalable fullstack, mobile, fintech, marketplace, and microservices products, with ownership of architecture, delivery, cloud deployment, and reliable payment experiences.

I founded and independently launched Yitewo, a zero-commission marketplace connecting residents across Senegal’s 14 regions with local shops, restaurants, and service providers. I built its NestJS backend, Next.js and React frontend, Flutter mobile app, multi-tenant vendor platform, geolocation search, and mobile money payments.

At Dahlia, I led the architecture of a social and event app covering ticketing, bookings, payments, and social feeds. I designed modular NestJS microservices, GraphQL and REST APIs, Stripe payment flows, event ingestion, a Flutter app, and a React admin portal.

I’ve also built secure fintech and digital platforms at City Money, Apporio Infolabs, TeamX-Group, and Jeulsima. My work spans wallets, transactions, high-availability microservices, e-commerce, booking systems, AWS deployments, Docker, CI/CD, and automated testing.
