Employment

  • Senior Machine Learning Engineer

    2022 - PRESENT
    Repustate
    • Developed novel and interpretable deep learning solutions for text in PyTorch by implementing and improving multiple research paper algorithms.
    • Implemented quantization strategies using ONNX, reducing model sizes by up to 5x and increasing inference time by up to 3x.
    • Designed and developed a new generation gRPC microservices API, allowing the main application, which is developed in Go, to communicate with Python deep learning servers.
    • Reduced server size by up to 8x compared to the previous generation API and increased inference speed by 2x-3x on average for prediction tasks.
    • Reduced the server size by up to 8x compared to the previous generation API.
    • Designed and developed AWS S3 schemas for production models and tokenizers.
    • Developed custom deep learning Docker images and RPM packages to be installed on on-premise RHEL/Linux servers. Tech used: RPM, AWS EC2, Docker, Git.
    • Orchestrated a continuous labeled-data generation pipeline that extracts labeled text using SQL daily and then stores the data in a designed S3 data lake to be used in future language models.
    • Designed and developed a custom MLflow tracking server to record and monitor experimentation results and artifacts.
    • Managed a multi-client portfolio (Banking, Govt, Healthcare, Marketing, Retail), led technical discussions on sales calls, and aided in landing over five clients.
    Technologies: Artificial Intelligence (AI), AWS S3, Algorithms, Deep Learning, Open Neural Network Exchange (ONNX), Hugging Face, gRPC, Protobuf, Git, Go, Python, PyTorch, Keras, MLflow, Amazon EC2, Docker, NumPy, Scikit-learn, Pandas

  • Data Scientist

    2020 - PRESENT
    Decathlon
    • Developed an in-house data-visualization pipeline that replaced a licensed tool saving $60,000 per year. Used SQL, Git, Jenkins, AWS cloud, Google Sheets API, and Google Data Studio.
    • Prototyped an NLU solution with customer reviews classification, keyword extraction, and sentiment analysis that outperformed a licensed tool, saving the marketing team $15,000 per year.
    • Created a visual search engine that was deployed as a product retrieval API. It's currently being used for product recommendations.
    • Built an unsupervised topic modeling solution for customer reviews with visualization, using sentence transformers. Improved original solution using GPT2 and prompt engineering.
    • Developed a store turnover forecasting tool using additive models and custom-made regressors (Prophet API).
    • Engineered an NLU product-article recommendation solution as part of Decathlon's personalization strategy.
    • Worked on data extraction, transformation, and loading tasks for each solution.
    • Made a sustainability reporting tool to monitor the performance of second-life and eco-designed products.
    • Built a color detection solution using k-means clustering to aid internal object detection models.
    • Interviewed new data science candidates, actively contributed to the hiring process, and mentored new interns on various data-related tasks.

Experience

  • AI Game Project and Report
    https://github.com/abdelatifsd/Comp-472---MiniMax-Algorithm

    This project was part of the AI course (COMP 472) at Concordia University. It includes a detailed report of the implementation strategy, minimax algorithm, and outcome analysis. The Jupyter Notebook has most of the code. The project didn't utilize any existing libraries. All algorithms and heuristics were implemented from scratch.
