David W.
Senior Data Scientist/AI Engineer
Freelancer based in Abu Dhabi, United Arab Emirates.
AI Engineer & Python Developer Master's in Artificial Intelligence · 5+ years building production AI and automation systems I turn messy data and manual processes into reliable, automated pipelines — with a focus on AI that produces accurate, grounded results, not confident guesses. 🤖 AI & LLM Applications RAG and document Q&A systems (OpenAI, Claude, self-hosted models), grounded answers with source citations, and guardrails that prevent hallucination. Experience in healthcare, insurance, and other compliance-sensitive domains. 📄 Document & Data AI OCR and extraction from PDFs, Excel, and scanned documents · text classification · structured, reliable output. ⚙️ Automation & Pipelines Web scraping (Selenium, BeautifulSoup, Playwright) · form automation / RPA · API integrations · ETL into MySQL — built idempotent and resumable so large jobs run reliably. How I work Clean, well-documented code and clear communication. I scope honestly, deliver in milestones so you see results early, and I'm comfortable picking up an existing codebase — if you've lost your original developer, I can step in and carry the work to the finish. Let's talk about what you're building.
