About Abdellah

I help companies build AI and Machine Learning systems that drive measurable business impact.

Over the last 7+ years, I have designed and deployed large-scale ML solutions across AdTech, Real Estate and Insurance, working on revenue optimization, recommendation systems, forecasting, bidding systems, fraud detection and GenAI applications.

At Teads (ex-Outbrain), I led multiple high-impact initiatives:

  • Ad pacing and forecasting systems contributing to ~$12M annual revenue uplift
  • Deep learning optimization models used for global advertising campaigns
  • Large-scale ML pipelines processing billions of rows with Spark
  • Research and experimentation on CTR prediction, multimodal embeddings and auction optimization

I combine strong business understanding with deep technical expertise across:

  • Machine Learning & Deep Learning
  • LLMs and Generative AI
  • Forecasting & Optimization
  • Recommendation Systems
  • NLP & Transformers
  • Large Scale Distributed ML (Spark, AWS)

I am particularly effective on projects where companies need:

  • production-grade AI systems,
  • measurable ROI,
  • fast execution,
  • and strategic guidance on ML product direction.

Tech stack: Python, PyTorch, TensorFlow, Spark, AWS, SQL, FastAPI, Scala, Docker, LLMs, RAG, Transformers.
