Lead Backend Engineer at Tern in Dubai. I build the software that moves money: when a tenant pays rent by card, my systems charge the card, record every dirham, and pay the landlord.
Shipping production software since 2017, mostly in Node.js, TypeScript, and PostgreSQL.

- Payments at Tern. I rebuilt the core payments system: charges, refunds, payouts, and provider integrations. AED 100M+ in rent has gone through it. Case study
- DeserTracker, my own product. A price tracker for UAE shoppers, so you can tell a real deal from a fake discount. 1.6M+ products and 12M+ price points, built and run by me alone. Case study
- Before that: Ekhtibary, an assessment platform that ran a live exam with 1,000+ students at once, and a social case management system for UNICEF. All work
- Making a Payment Retry Safe
- Running an AI Code Reviewer in Production
- Why an Idle Postgres Connection Crashed My Node.js Service
- My AI Agents Took Down My Own Server
Plus a lot of homelab posts: unRAID, Zigbee, backups, and self-hosting. All posts
Two Udemy courses: Knex.js and PostgreSQL and a URL shortener in TypeScript and Koa. Course code: English, Arabic, Knex.js.
