Thomas Sprinkmeier
Worked on the usdot-fhwa-OPS/V2X-Hub repository, focusing on backend development and database security. Delivered secure password storage by implementing SHA-256 hashing and updating SQL insert statements, directly addressing a credential protection issue. Improved repository hygiene by standardizing file permissions from 100755 to 100644 across multiple components, reducing permission-related risks and supporting audit readiness. The technical approach emphasized secure coding practices and maintainability, with changes spanning .devcontainer, documentation, and plugin directories. Utilized C++ and SQL to enhance both security posture and code quality, ensuring safer handling of sensitive data and more consistent repository management for ongoing compliance needs.
