Ruby on Rails engineer at MASDR MENA building production SaaS APIs, payment integrations, and LLM features.

At MASDR MENA, I build and maintain a production Rails 8 API for a B2B SaaS marketplace, including payment integrations with Paymob, Geidea, and InstaPay. I also shipped LLM features and use Claude Code and LLM APIs in my daily work.

I introduced RSpec to the codebase, adding parallel testing and PR-gated CI. I built asynchronous payment and subscription flows, real-time chat, and alerts, and owned AWS deployment and reliability.

At SwiftX, I contributed to products including Mozdaher, a multi-tenant e-learning CMS, and Abqarino, a REST API for a React Native app. I’ve also reviewed and mentored student projects at Microverse, and volunteered with the Egyptian Red Crescent.
