Hello World

I’ve been meaning to start writing for a while now. This is me finally doing it.

Who am I?

I’m Wael — a Data Scientist and AI Engineer based in Saxony, Germany. I spend most of my time building privacy-first AI systems for healthcare, where the constraints are real: air-gapped networks, encrypted data, strict PII redaction, and zero tolerance for mistakes.

I lead the technical side of AI products in healthcare, where we process over 100k clinical documents daily across systems supporting 1.5M+ patients in the UK. On the side, I’m a research assistant at Hochschule Mittweida, working on computer vision for space applications — detecting stress signals in plant roots under low-gravity conditions.

Before all this, I taught data science to cohorts of 200+ students in Saudi Arabia, worked as a BI analyst at a clinical research company in the US, and studied everything from supply chain logistics to applied mathematics.

What will I write about?

Mostly things I learn and think about at work:

• NLP in production — the gap between a model that works in a notebook and one that handles 100k documents a day
• Privacy-first AI — what it actually takes to deploy ML in air-gapped, regulated environments
• Computer vision — document understanding, research imaging, and the occasional space experiment
• The craft of building ML systems — evaluation, deployment trade-offs, and the decisions that don’t show up in papers

I might also write about tools I find useful, problems that took too long to debug, or ideas I want to think through out loud.

Why a blog?

I’ve learned a lot from other people writing about their work. Blog posts that explain what actually happened — not the polished conference version — are some of the most useful resources in this field. I’d like to contribute to that.

No posting schedule, no newsletter. Just writing when I have something worth sharing.
