III · What I've built

Chapter 01

Bayan

Saudi Regulations & Decisions Data Hub

Finding a regulation is easy. Understanding how it changed over time is a different problem.

Bayan transforms Saudi regulatory information into structured, version-aware datasets to support regulation exploration and historical analysis.

Context: Collaborative capstone developed during the Saudi Digital Academy Data Engineering Bootcamp.

Stack: Python · Apache Airflow · PostgreSQL · Docker · SeaweedFS · FastAPI · Power BI

CollectStage 1 of 4

Extract regulatory information from the Saudi Bureau of Experts using Python and preserve raw data in S3-compatible object storage.

Chapter 02

Sentinel

Healthcare Data Observability

The pipeline is green. But is the data healthy?

Sentinel explores how data pipelines can run successfully while silently delivering unreliable data, using synthetic healthcare records to investigate data quality and observability.

My role: Technical Lead & Data Engineer
Context: Data engineering observability project built on synthetic healthcare data.

Technology areas: Python · Synthea · FHIR · Cloud storage · PostgreSQL · Streaming · Data quality

Case study · coming soon

Select a stage to explore

StreamStage 1 of 4

Generate synthetic healthcare records using Synthea and FHIR, then ingest them into a controlled data pipeline.

Beyond the Pipeline: Leading the Team

I lead Sentinel's development while contributing directly to its engineering.

Najm

AI-Powered Accident Detection & Reporting

What if accident reporting could begin before anyone makes a call?

An AI-assisted accident reporting prototype combining computer vision, drone imagery, backend services, and a mobile application.

Recognition: Third Place — CCSIT Graduation Projects, King Faisal University, 2024
Type: Academic capstone prototype · Najm Accident Reporting System

Stack: Python · YOLOv5m · Flask · MySQL · Flutter · Computer vision

Case study · coming soon
