At Thadda Arabic Quiz Platform, I designed a Gemini-powered content generation service that produced 10,000+ unique quiz questions while maintaining a 95% quality threshold. I also built a multi-pass validation pipeline that cut manual review by 75%, along with a REST API and moderation dashboard.

At Betida Entertainment Ltd, I owned the identity and authentication layer across four repositories, including a custom Keycloak extension with two-factor authentication and social login. I’ve also built Go services for AWS and Azure storage, booking and reporting pipelines, and an AI content management system.
