Feb 1, 2026February 2026 — Hack-PSU/apiv3: Key features delivered, privacy improvements, and maintainability enhancements across the codebase. Key features delivered: - Reimbursement Form Enhancements and Privacy Controls: dynamic handling of mailing addresses by submitter type, updated form version, and ensuring organizers' mailing addresses are not displayed in requests. Commits: a546bd8571d43cf80c3418b4bdc8025d7b55f5f9; 0de2894b17387057312e15008db2fc1048dc6276. - Applicant Scoring Metrics Storage: added a new database migration to create the applicant_scores table to store scoring metrics for users in hackathons, including fields for hackathon_id, user_id, statistics, and a prioritization flag. Commit: 4ac166fe5d10aacd959687d7c3369c2e6cceabf2. - Codebase Naming Convention Refactor: camelCase naming for the registration entity and registration controller to improve consistency and maintainability. Commits: aa2e97f0f1ba3c7b47e6f8c468dfdb847370c104; f08c5acca5fc7ac3a36651e9c2d532ac18cc541f. Major bugs fixed: - Privacy-related fix to prevent organizers' mailing addresses from appearing in requests, addressed as part of the Reimbursement Form Enhancements. Overall impact and accomplishments: - Strengthened privacy compliance, enabling safer handling of personal data in reimbursement workflows. - Improved analytics readiness through the applicant_scores migration, enabling better insights into hackathon scoring metrics. - Increased codebase stability and maintainability via consistent camelCase naming across registration components. Technologies/skills demonstrated: - Backend migrations and data modeling (applicant_scores). - Dynamic form logic and PDF/form versioning. - Code refactor and naming conventions (camelCase) for maintainability. - Version control discipline with clear commit messages for traceability.

Oct 1, 2025October 2025 (Hack-PSU/apiv3) delivered meaningful backend security, data accessibility, and API enhancements with measurable business value. Key outcomes include consolidating reservation-related changes into a single, cleaner workflow: removing explicit UUID generation for new reservations, enforcing TEAM-based access for creating/deleting reservations, and refactoring Firebase privilege checks for clearer authorization. Broadened data access: Find All Locations endpoint now allows NONE role, simplifying data consumption where appropriate. Robust data handling and validations: photo uploads now consistently name files with userId and properly handle missing user information with unauthorized errors; inventory item patch updates enforce correct DTO usage and require presence of name, asset tag, or serial number. Data modeling and API capabilities expanded: added a nullable GitHub link column to projects for linking repositories; introduced a dedicated MLH Registration Data Export Endpoint to join user and registration data for active hackathons. Maintenance and stability: database migrations cleaned up by removing redundant indexes and refining down migrations. Overall, these changes improve security, developer productivity, data quality, and business tooling for hackathon operations.
