PROFILE
Don Johnson
Don developed two targeted features over a two-month period, focusing on healthcare load testing and secure prompt engineering. For the grafana/k6-extension-registry, Don built an XK6 EDI extension that generates HIPAA X12 EDI transactions, expanding the registry’s support for enterprise healthcare scenarios and enabling more comprehensive load testing of sensitive workflows. In danielmiessler/Fabric, Don introduced the greybeard_secure_prompt_engineer pattern, establishing production-grade guidelines for secure input and output handling to mitigate prompt injection risks. Both projects leveraged skills in data formats, extension management, and security engineering, with work delivered in Markdown and yaml, demonstrating depth in system design and implementation.
