Aug 1, 2025August 2025 highlights: Delivered two front-end features that improve user experience and alignment with business calendars, plus a critical UI bug fix. Key features delivered include Nollning 2025 Events and Content Updates, which aligned event scheduling with updated weekStarts, filtered publications to 2025, and fixed the reveal time to 14:00, ensuring accurate timing and content eligibility for the 2025 Nollning season; and UI Asset Performance Improvements, which compressed WebP assets and removed unused SVGs to reduce bundle size and improve load times. Major bug fixed: UI Bug Fix for Homepage Readme Removal, restoring visual integrity by removing a broken component. Overall impact: more reliable event scheduling and content eligibility, faster pages with lower bandwidth usage, and a cleaner homepage, contributing to better user experience and higher operational readiness for the 2025 season. Technologies/skills demonstrated: front-end optimization (image compression, asset pruning), content filtering and scheduling logic, and disciplined version-control practices (chore and fix commits).
