I maintain ventilators in ICUs in the morning, build data pipelines in the afternoon, and engineer CVs that get people hired in the evening — not by accident, but by design. Precision over speed is not a tagline. It's the methodology I apply across every domain, without exception.

🏥
Clinical depth — not textbook theory Real hands-on maintenance across 6 departments — ICU ventilators, OR anesthesia machines, radiology imaging systems, and more.
Data engineering with clinical context Building pipelines with Python, Azure, and Spark — with firsthand understanding of the clinical data behind them. That context is rare.
Freelance services built on engineering standards CV writing, LinkedIn optimization, and Excel solutions delivered with the same accuracy I bring to clinical calibration. Every output is verified, not estimated.
🌐
Bilingual — native Arabic, professional English Serving regional and international clients simultaneously — culturally adapted Arabic and professionally precise English, on 11 platforms.

I fix broken ventilators, broken pipelines, and broken CVs. The tools are different. The standard is the same.
