How I work

Self-employed since 2024: client work and my own products, from the first conversation to a running deployment.

  1. 01

    Start with the people

    I work out how the job gets done today before I design anything. REDMARS grew with a Kabul hospital as design partner; Al-Raheel replaced an agency’s Excel process.

    See it inREDMARSAl-Raheel Travel Agency

  2. 02

    Model the data first

    A solid schema makes everything after it simpler. REDMARS runs on 47 PostgreSQL tables; Al-Raheel uses triggers and views for its complex queries.

    See it inREDMARSAl-Raheel Travel Agency

  3. 03

    Build the API and the interface

    Typed APIs with interfaces made for the people using them: bilingual right-to-left screens, a desktop app, a 3D phone controller.

    See it inREDMARSPrescription Management AppSolar Taxi Roof Sign

  4. 04

    Make it safe

    Rules are enforced on the server, not just hidden in the UI: 6 roles and about 60 permissions, an audit trail, allergy hard-blocks at prescribing, hashed passwords and httpOnly sessions.

    See it inREDMARSTrendora

  5. 05

    Ship it and keep it running

    Load-tested with 40 concurrent patients, fixed a connection-pool exhaustion, then shipped in Docker containers behind HTTPS with nightly backups and a verified restore.

    See it inREDMARS

Alongside the work: B.Sc. Computer Engineering at Kardan University, expected April 2028.

Let's build something useful.

Open to roles and projects. Email is the fastest way to reach me.
