Over 16 months, contributed to cityofaustin/vision-zero by building and refining a robust data management and analytics platform for traffic safety. Developed features spanning UI/UX, backend APIs, and database schema, focusing on data integrity, access control, and workflow efficiency. Leveraged React, TypeScript, and GraphQL to deliver reusable components, advanced filtering, and secure authentication. Enhanced data modeling and migration safety using PostgreSQL and SQL scripting, while implementing permissions and audit trails for sensitive operations. Maintained code quality through linting, documentation, and modularization. The work enabled safer editing, richer data storytelling, and reliable deployment, supporting both operational needs and long-term maintainability.
In April 2026, the Vision Zero team delivered critical UI and data-model enhancements that improve data capture accuracy, user productivity, and system reliability, while solidifying data integrity and permission controls. Key features include a Contrib Factors system with a modal UI, editing on the fatality unit card footer, and temp-record handling with related data lookups/queries; extended unit type data model to include IDs for related entities; and a GraphQL dependency upgrade to ensure performance and compatibility. The crash data refresh workflow was hardened by wiring refetch callbacks from the parent component and ensuring data is re-fetched after saves. UI permission controls were tightened to show edit/add options only for non read-only users, reducing risk in editing flows. Additional improvements included Charges modal integration, data query enhancements, and ongoing UI/QA hygiene (linting, migrations, and formatting).
