Index
Multi-tenant legal-compliance SaaS, isolated at the database and on the queue.
A property search that did not filter, rebuilt around one canonical hierarchy.
The frontend of an Arabic AI answer engine, rebuilt around streaming.
Beyond these three
A warm-intro network for founders, hiring managers, investors and people looking for work. Members offer an intro without revealing who they know, only the role, company or sector, and ask for the intros other members can make. Whoever makes an intro knows the person they are introducing. Everyone starts with one credit: asking for an intro holds it, it comes back if the intro does not happen, and making one for someone else earns another. Nobody can buy credits, or an intro.
See it liveSet the frontend architecture for Dubai’s open property and services marketplace. Rendering strategy, data fetching, where validation actually lives. I built the shared component library the other engineers worked from, and dragged a legacy Express HR system into a modular monolith along the way. Listing endpoints were slow, so I went digging: profiled the slow queries, indexed three expensive joins, retuned MySQL. p95 latency came down about 25%, checked against two weeks of production traffic.
Laid the founding architecture for a new ERP platform meant to be resold as a product. NestJS, PostgreSQL, Redis, BullMQ, Docker, AWS, Terraform, GitHub Actions. Then I hired the four engineers who built it and led them, setting the event-driven design, the environments, and the CI/CD foundation they worked against.
What I’m looking for
A full-time senior role where I own a system end to end, and where the hard calls are mine to make. Remote anywhere, or on-site in Dubai. If that’s open on your team, email reaches me fastest.
