PROFILE
Janson Bunce
Janson Bunce developed and maintained core security and data synchronization features for the cisagov/XFD repository, focusing on scalable backend workflows and robust access control. Over 11 months, Janson engineered API endpoints, data export pipelines, and vulnerability scanning integrations using Python, Django, and TypeScript. He implemented organization-scoped synchronization, serverless deployment optimizations, and Elasticsearch-backed search and export, addressing multi-tenant reliability and large-scale reporting needs. His work included rigorous test coverage, CI/CD improvements, and security hardening for authentication and admin controls. The resulting codebase demonstrated depth in backend architecture, data integrity, and maintainability, supporting secure, high-throughput operations for security analytics.

Jun 1, 2025June 2025 (cisagov/XFD): Delivered security, data reliability, and code quality enhancements that drive business value and client confidence. Implemented PSHTT-based HTTPS security checks with pshtt_scan and pshtt_sync to expand domain-wide security posture analysis and synchronize results across configurations. Added deterministic ordering to the v2 Organizations endpoint (order_by created_at) to improve data predictability and client reliability. Performed comprehensive codebase cleanup to remove unused code and reorganize domain/org schemas, resulting in cleaner linting, more stable tests, and clearer error messages. These changes reduce risk, improve CI stability, and provide a stronger foundation for downstream analytics and integrations.
