About Adel

I transform your data into truly usable decision-making models and AI solutions in production: scoring, anomaly detection, and LLM/RAG (semantic search on internal documentation).

Pragmatic, impact-oriented approach:

KPI → POC → metric validation → industrialization.

What I deliver (concrete deliverables)
  • Scoring & segmentation: churn, risk/fraud, lead scoring, prioritization, qualification (models + features + evaluation + interpretability).
  • Anomaly detection & monitoring: unusual behaviors, alerting, drift, data quality (metrics + thresholds + tracking).
  • LLM / RAG & NLP: semantic search, information extraction, classification, summarization, document automation with sources/citations.
  • Data visualization / reporting: dashboards and automated reporting (based on your tools).
Work methodology

Quick scoping (objective + KPIs) → functional prototype → measurement (metrics) → recommendations → production deployment (tests, logs, docs, versioned code) + transfer to teams.
Stack: Python, SQL, pandas, scikit-learn, XGBoost, PyTorch/TensorFlow, FastAPI, Streamlit, LangChain/Langgraph.

Objective: deliver robust, understandable solutions used by your teams.
