About Amal

AI Engineer & Data Scientist, graduated from the AI Master's program at École polytechnique (X), I design and deploy robust, explainable, and industrializable AI solutions, directly aligned with companies' business objectives.

My training at Polytechnique has provided me with a deep understanding of the theoretical and practical foundations of AI: advanced machine learning, deep learning, generative AI, optimization, statistics, MLOps, as well as the challenges of model security, ethics, and reliability.
I combine this scientific rigor with a strong product and business culture.

For over 5 years, I have been helping SMEs, scale-ups, and startups transform their data into concrete growth levers: predictive models deployed in production, recommendation systems, AI agents, intelligent automation of business processes, high-performance chatbots, and decision support tools.

My approach:
start with your strategic objectives, identify use cases with rapid ROI, then deliver solutions that are used, maintainable, and scalable, integrated into your existing systems.

What sets me apart:

– Solid AI expertise from École polytechnique, applied to real-world cases
– Performance, reliability, and business impact-oriented approach, not buzzwords
– Solutions understandable and usable by business teams
– End-to-end vision: strategy, data, AI, industrialization, and deployment
– High standards for security, confidentiality, and cost control

My services:

• Data & AI Strategy Audit (use case prioritization, clear roadmap)
• Development of custom AI solutions (prediction, recommendation, generative AI)
• Intelligent automation of business workflows
• Reliable and high-performance AI chatbots & assistants
• Decision-making dashboards and management support tools
