About Abdulrhman

How I work and lead

Based in Egypt. Building web products since 2018, full-time since 2021.

How I work

I assume state changes while code waits: PACS checks tenant scope again after every lazy import.

I validate at boundaries, not only in the interface: the LMS and its embedded viewer each check origin, question and attempt before restoring an answer.

Written up with code: running a DICOM viewer under a strict security policy, restoring DICOM answers across windows and matching recordings to their credits.

How I lead

At Craft Crew I lead 6 engineers building Telegnost PACS, Telegnost LMS and CTMS.

I write the plan for larger features and review every pull request. Auth, tenancy, billing and clinical-data changes get extra review. CI must pass to merge; releases ship each sprint and I approve them.

I interview candidates, run one-to-ones and pair on the hardest problems.

One decision: a library in the PACS viewer didn’t work under the portal’s strict security policy. I kept the policy and had us replace the library. More on the PACS page.

Part-time, since September 2023, I’m contracted to ArtistHub LLC for ArtistHub, Nvoko and True North.
