Master’s graduate in Applied Mathematics with 5+ years of experience in statistical learning, optimization, and data-driven decision-making. Proficient in R, SQL, Python, and Power BI for data transformation and visualization. Experienced in end-to-end machine learning modeling in financial contexts and developing production-ready optimization models tailored to customer requirements. Owner and Co-founder of UP.
About Me
Investigated data and sources of low quality data. Taken actions have cured 80% of data and then augmented using GAN architectures to study weather causality on HIV patients. Causality analysis is also achieved using Bayesian ML and Distributed Lag Non-Linear Models (DLNM).
Developed a comprehensive cleaning service website using Django 5.2 with bilingual (English/French) admin dashboard, dynamic content management, and integrated OpenAI API chatbot with customizable templates to answer customer queries and increase reachability.
Features user authentication, testimonial management, gallery system, company logo management, and responsive design. Implemented custom admin panels with AJAX operations, media file handling, and multi-language support.
Deployed on Heroku with cloud storage integration, demonstrating full-stack development skills, database design, and modern web development practices.

Developed a PySpark job optimized regarding joins, UDFs, broadcasting and bucketing to reshape data into metrics to analyze and deployed it using EMR AWS service Link to PySpark example of created jobs
Developed, scheduled ETL functions to collect open cities data from open APIs. Dimensions and fact tables are defined for easier analytics options and unique data structure for different sources. Tables are filled incremetally to minimize processing resources and then tracked with SCD tables for streak analysis. Similar minimal works are available under my Github repository.
Developed a comprehensive sales dashboard for IT products at Alten using Power BI, where I integrated and normalized raw sales data from multiple sources through Power Query. I created dynamic measures with DAX for real-time insights and designed interactive visualizations to highlight key metrics like net sales quantities and category-wise breakdowns. This project involved advanced data processing techniques and aimed to empower stakeholders to make informed decisions based on detailed data insights.
Developed a shiny application that automates ANOVA statistical insights and conclusions for a lab processing Olive oil in Tunisia Get Sample of data here

The content of this book is widely shared in youtube tutorials by the author, however I enjoyed the paper version alongside the video they were able to make direct massive impact on my consideration while building a dashboard.
I'm still reading it ...
I still have chapters to go for deep understanding however I managed to implement live all contents of chapter 3 on my youtube channel for arabic speakers. This book is your ML bible !
I didn't enjoy much this book as I did for the same content of Dimitri's book...though I may consider it a good beginning to put hands on RL.
Much effort to put in here ! not easy at all
at first, it's super hard but you get used to it. On my channel there are problems I solved while explaining essentails of this gem and Dimitri's DP as well !
Talented, technically solid and very driven Data Analytics Scientist. Ali joined my team in France to work on his graduation Internship. His inquisitive nature and strong ability to learn allowed him to quickly understand the basis principles of a new domain for him, agriculture, and effectively apply his data science knowledge to work on specific business problems. He demonstrated solid Project Management skill, delivering good-lasting value to the team and committing to timelines. His optimistic nature and always positive attitude made it enjoyable for the team to work with him. Ali will be a great asset to any team looking for a solid Data Analytics' Scientist.
Ali is an excellent professional, I was able to assist him during his internship at Monsanto legacy/ Bayer. He is very proactive and committed to self-development, is always looking to be collaborative in projects and has a very expressive Statistical/ Programming background. It was a pleasure working with you Ali!
Working with Ali at Axe finance was such a blessing. His tremendous spirit to learn and move forward with the projects was very inspiring. He is a valuable member for the team and I highly recommend him.
