Apr 1, 2026April 2026 frontend monthly summary highlighting key features delivered, major bugs fixed, and overall impact. Focused on delivering business value through targeted UI improvements, robust cache handling, and enhanced testing capabilities to accelerate development and improve user experience. Key outcomes include a localStorage-based Dashboard Testing Enhancement to enable flexible testing of multiple Superset dashboards without altering the main dashboard, a UI refinement in Wallet Transactions to hide the non-traceable wallets' Available column for clearer presentation, and a defensive Apollo cache handling fix that filters null entries and corrects cache eviction logic across the integrations list to prevent crashes and ensure reliable deletions. These efforts collectively reduce risk, improve product quality, and demonstrate strong frontend patterns, data handling, and performance-oriented mindset.
