About
Senior engineer, freelance-first — building reliable financial infrastructure for startups and enterprises worldwide.
I am an independent backend and fintech engineer focused on payment systems, distributed backends, and enterprise APIs — built for Africa's realities and trusted by international clients who need production-grade delivery.
Beyond writing code, I contribute to system architecture, API design, engineering standards, and junior engineer mentorship— the work that keeps teams shipping reliably when complexity and traffic grow.
Strong Java & Spring Boot background, event-driven architectures with Kafka, and Angular/TypeScript for full-stack delivery when needed.
Based in Dakar, Senegal (GMT). Available for international freelance and contract engagements. Long-term interest: building financial infrastructure products from the ground up.
