AI & Machine Learning Engineer building Arabic legal RAG platforms, multimodal triage prototypes, and automated business workflows.

I built Kawaneen, an Arabic legal AI platform with hybrid retrieval, reranking, citation-grounded answers, and safe abstention. In a controlled evaluation, structure-aware chunking improved nDCG@10 from 0.639 to 0.684, and citation-contract defects fell from 29/40 to 0/40.

For RuralStroke Triage, I developed an offline-capable decision-support prototype combining facial video, speech, symptoms, and patient metadata. I created reproducible vision and speech pipelines and evaluated model branches, robustness, and edge runtime, alongside usability studies with collectors and clinicians.

I also built OpsFlow AI, a purchase-order workflow with structured LLM extraction, deterministic validation, and human review. It integrated Odoo, HubSpot, Gmail, and Slack, with PostgreSQL persistence, recovery controls, and audit trails.

At Summit Technology Solutions, I contributed to C#/.NET application development and designed a mock school database with SQL-oriented models. I completed BSc Computer Science studies at the University of London, with final results pending and an expected First Class Honours.
