December 2025: Delivered notable front-end and back-end improvements across Metatavu/metatavu-home and Metatavu/home-lambdas, focusing on user experience, admin workflows, data integrity, and cloud/storage robustness. Front-end UI refresh improved clarity and actionable status indicators; admin workflow enhancements enabled better onboarding flows. Calendar now enforces end-of-week boundaries, preventing navigation to future or past ranges that could cause data inconsistencies. Backend/storage modernization upgraded S3 integration with get/put presigned URLs, improved logging, error handling, and validation, plus consolidated configuration and environment wiring. Data handling improvements included sortable allocations and non-admin project filtering, improving data exploration and operational efficiency. Bug fixes targeted vacation calculations, checkbox syncing, and code quality updates, resulting in more reliable releases and reduced maintenance overhead.
