## About

```text
At Neo (Chaatr), I built automatic school timetable generation with live Socket.IO progress and delivered a live-classroom suite with chat, polls, collaborative documents, and attendance reports. I also shipped AI meeting features, including transcript summaries, Arabic-safe PDF slide decks, and live captions.

At Figr, I built a Shopify app end to end, including its OAuth service, Admin GraphQL integration, and GDPR and order webhooks. I also implemented usage metering and billing for Shopify and non-Shopify stores, and added platform security controls.

At Massar E-Learning, I lead the backend team for a multi-tenant LMS with scheduling, live sessions, AI course search, and payment and messaging integrations. At Popups, I built event-driven microservices supporting 20,000+ concurrent users and wrote a Go backup and recovery service.

Earlier, at TakiAcademy (Locaux) & client projects, I built a staff and finance management platform and delivered client web projects. I’ve also contributed merged pull requests to Jitsi, Dokploy, and Agenta-AI.
