A collection of work completed during the Hydroficient externship, showing applied tasks and learning outcomes in IoT security and defensive practices.

  • Database Management & Query Platform
    Database Management & Query Platform

    Designed and normalized a PostgreSQL database for a 300,000+ row HMDA mortgage dataset, implementing data cleaning, transformation, and relational query logic to ensure data accuracy and consistency. Developed a Python-based natural language interface that converted user questions into executable SQL queries. Built a GUI enabling non-technical users to perform joins, filtering, grouping, and aggregate analysis without writing SQL, making the system accessible to end users.

    PythonPostgreSQL
  • Binary Bomb Reverse Engineering Lab
    Binary Bomb Reverse Engineering Lab

    Reverse engineered a compiled binary executable to determine valid inputs across multiple challenge phases by systemically diagnosing program behavior. Utilized GDB and x86 assembly analysis to troubleshoot and inspect memory structures, control flow, and runtime behavior. Reconstructed hidden program logic through methodical debugging and successfully identified required execution paths.
