PROFILE

Hany Mostafa

Worked on awslabs/amazon-documentdb-tools and awslabs/data-on-eks, focusing on backend reliability and partner integration. Addressed MongoDB collection statistics retrieval by correcting command usage and adding defensive checks for wiredTiger data, which improved database stability and reduced runtime errors. Enhanced Atlas compatibility by refining cardinality checks, excluding oplog.rs from processing, and improving collection name verification logic to support MongoDB Atlas workflows. Later, delivered the DataPelago Partner Integration for awslabs/data-on-eks, enabling accelerated Spark workloads and cost optimization. Demonstrated skills in Python, backend development, and database management, with an emphasis on robust, maintainable code and collaborative integration with partner teams.
