Employment

  • Senior Software Engineer

    2018 - PRESENT
    Careem Networks FZ
    • Developed a city-to-city product that was shipped to more than 50 cities in the MENA region.
    • Developed a matching algorithm for carpooling. It was used for food delivery at the begging of COVID-19 crisis.
    • Built a catalog platform for merchants to be able to handle millions of product injections per hour.
    Technologies: Java, Spring, Go, React, Kotlin
  • Full-stack Software Engineer Intern

    2015 - 2015
    Facebook
    • Collaborated with the scuba team to achieve aggregation of the results from the back end.
    • Converted the front-end components using React.
    • Conducted end-to-end testing of the tool used internally by all software engineers and PMs.
    Technologies: PHPT, React, C
  • R&D Software Engineer Intern

    2014 - 2014
    Microsoft
    • Integrated a deep neural network into a video classification application.
    • Trained and improved the DNN for video classification for homemade videos (low-quality videos).
    • Extracted keyframes to achieve video summarization.
    Technologies: C#, DNN

Experience

  • Catalog Platform

    Worked on building a catalog platform that manages the products data for merchants and restaurants and allows editing, bulk uploading, and POS integration. It's also able to scale to ingesting millions of products per hour.

  • Carpooling Solution
    https://blog.careem.com/en/careem-sawa/

    Helped develop a carpooling solution by implementing an algorithm for immediate carpooling matching with other ongoing rides. Used heuristics and route generation techniques to provide a near-optimal route. The project was used in more than 50 cities across the MENA region.

    The same algorithm was later integrated with the food delivery, and we were able to pool delivery orders during high volumes of orders.

  • Intercity Travel

    Introduced a solution for traveling between cities, worked on the whole flow as a full-stack engineer, and built the solution from the front-end design as back-end service serves the React front end for both IOS and Android. The back end was built in Go to serve the data and configuration and create A/B testing experiments for the design.
