What I'm looking for

I’m looking for a security-first backend/platform role where I can own delivery end-to-end—from architecture and infrastructure through production—partner with stakeholders on enterprise readiness, and keep shipping across web and mobile.

I’m the sole engineer who’s taken a healthcare SaaS platform upmarket, designing and shipping enterprise SSO now live with a regulated French healthcare group. I architect multi-region data residency for GDPR (control-plane/data-plane separation, immutable audit logging, secrets rotation), and I translate complex security/compliance requirements into actionable, bilingual (EN/FR) delivery.

Across my career, I ship end-to-end through infrastructure and production—hardening auth flows, owning incident diagnosis from log evidence, and delivering major features across backend and multiple frontends. Previously, I led engineering at a legal-tech startup and built bank-grade asset-financing and payment systems across African markets, while also delivering customer-facing conversational experiences.
