PROFILE
Shikou
Shiko Dejima contributed to the nttcom/threatconnectome repository by engineering robust threat intelligence and vulnerability management features across the stack. Over ten months, Shiko delivered API integrations, authentication migrations, and frontend refactors using Python, React, and SQLAlchemy. Their work included modularizing validation logic, migrating authentication from Firebase to Supabase, and enhancing data models for safety impact analysis. Shiko improved end-to-end test reliability, streamlined CI/CD pipelines, and refactored SBOM parsing for better data integrity. By unifying terminology and standardizing workflows, Shiko reduced maintenance overhead and improved release safety, demonstrating depth in backend, frontend, and DevOps practices throughout the project.

Aug 1, 2025August 2025: Cross-stack refactor to standardize ticket handling terminology and stabilization of end-to-end tests for threatconnectome. The team renamed the VulnStatus enum to TicketHandlingStatus across the database schema, models, business logic, APIs, and frontend, and fixed E2E test assertions to reflect actual UI behavior. These changes reduce test flakiness, improve maintainability, and lay groundwork for safer feature development.
