Feb 1, 2025

February 2025 — DemocracyClub/EveryElection: Delivered a focused API performance optimization for the Election API by conditionally prefetching related election data only when beneficial (identifier_type != 'ballot'). This change reduces database queries for single-ballot requests and improves response times in common paths. Implemented a guard to ensure prefetching occurs only when appropriate (commit 98953ec9c1960115a3582067dca14871a0b7b8ec). Added test coverage to verify query counts for detail views, safeguarding performance as data scales.

January 2025: Implemented API pagination cap (MaxSizeLimitOffsetPagination) to prevent DoS from overly large API requests in DemocracyClub/EveryElection. Added configurability via settings and test coverage to verify capping behavior. This change reduces backend resource risk, improves API reliability, and demonstrates strong TDD and DRF pagination skills.

December 2024 monthly summary for DemocracyClub/UK-Polling-Stations: Implemented CloudFront Basic Authentication for development and staging by adding Authorization headers to the CloudFront configuration. This change gates non-production access, reducing the risk of unauthorized data exposure during testing and demos. The work was completed with a single commit (Add Authorization headers to CloudFront) and establishes groundwork for future environment-specific access controls. No production-facing bugs were reported this month. Overall, this milestone strengthens security posture and supports safer, faster development and QA cycles.
