At KLAO, I own Paddle billing and checkout, contribute to new features and projects, and led and mentored a team of three engineers. I also configured production SSO with Keycloak and OpenID Connect across KLAO applications.

I built Fandem AI, a multi-tenant SaaS platform with an embeddable AI chat widget for MENA e-commerce. At Sumerge, I developed backend microservices and batch and stream processing services, and contributed fixes to OpenTelemetry Java.
