February 2025 monthly summary: Focused on cross-repo code quality improvements through standardized formatting. Delivered cosmetic code cleanup across three PublicisSapient KnowHow repositories using Spotless, improving readability and maintainability without changing functionality. This groundwork reduces review diffs, lowers onboarding cost, and strengthens CI hygiene. No functional bugs fixed this month; primary work was formatting and consistency. Key highlights across repos include knowhow-common, knowhow-processors, and knowhow-api with two Spotless-based commits each. Detailed changes below.

January 2025 (PublicisSapient/knowhow-api): Delivered foundational improvements to enable local development and enhanced cache performance with improved observability. Focused on configuring a local dev environment and implementing TTL-based cache eviction to boost responsiveness and reduce stale data.

November 2024 — Key outcomes across knowhow-common, knowhow-api, and knowhow-processors. Key features delivered: - knowhow-common: Project State Management and Active Projects API introduced 'On Hold', differentiates between all vs active projects, and adds a cache constant. Commit: 1b2deba639ae984189d87fe86c1a0355dca17221 (DTS-41527). - knowhow-api: Project State Management and API Filtering differentiates active vs on-hold; endpoints to fetch all or only active projects; updated caching for state reflectivity. Commit: e572ea7b6d6beff6dc917ce545e5dcb97e85f191 (DTS-41527). - knowhow-api: Ehcache-based KPI data caching and logging; caching for aggregated KPI data; CacheEventLogger; property updates for expiration/eviction. Commit: 61d9fda4de698cc21a197523e9b8f53cb2e6bdd4 (DTS-39742). - knowhow-processors: Project State Management adds 'active' and 'on-hold', APIs updated, cache invalidation for consistency when project states change. Commit: 0b1aeb87d52303007e8532cd5d2b4e060af14a73 (DTS-41527). Major bugs fixed / stability improvements: - Ensured data freshness and consistency with explicit cache invalidation on state changes. - Reduced KPI query load through Ehcache-based caching and improved observability via cache logging. Overall impact: - Faster, state-consistent project queries; improved KPI dashboard reliability; scalable caching strategy across services. Technologies/skills demonstrated: - Java-based API design, cross-repo state management, Ehcache caching, cache invalidation, cache event logging, configuration management.
