June 2026 monthly summary focused on delivering robust time-management metrics and hardening data integrity for chess-dojo-scheduler. Delivered a comprehensive Time Management Rating System that computes per-game ratings from PGN clock annotations, aggregates them per user, and includes a backfill script for existing data. The feature is surfaced on user profiles with provisional indicators and uses a shared internal library for clock-based ratings. Completed backend cleanup for deleted games and phantom directory entries with a one-time migration script; IAM permissions were updated to support cross-table operations. Implemented tests for time management calculations and the backfill workflow, and performed a refactor to decouple TimeManagement as an internal aggregate from external rating systems. Result: more accurate user profiles, fewer phantom 404s, and a robust rebuild workflow when data changes occur. Technologies/skills demonstrated include Go/TypeScript backend, DynamoDB, shared rating library, unit/integration tests, IAM permissions, and frontend UI updates.

April 2026 monthly summary — Key features delivered, major bugs fixed, and impact. Delivered two high-impact feature updates for jackstenglein/chess-dojo-scheduler, focusing on clarity, reliability, and editing UX. The ExpirationChip Tooltip Enhancement now shows the exact expiration date in the tooltip, with edge-case handling for tasks with and without progress and aligned with expiration logic. The Game Annotation Clock Editor Usability Improvements introduce unsaved-changes warnings, keyboard navigation between time fields, explicit error states for invalid inputs, and auto-focus behavior to streamline data entry. These changes reduce user confusion, prevent scheduling mistakes, and accelerate analysis workflows. This work delivers measurable business value by improving task visibility, reliability, and editing efficiency.

March 2026 achievements focused on user empowerment, data quality, and reliability for the chess-dojo-scheduler product. Delivered on-demand rating refresh, date-based game sorting with a backfill path for existing data, reliability improvements for Lambda-backed workflows, and real-time notifications to mentors when a game review is submitted. These changes collectively enhance user experience, reduce operational friction, and improve data accuracy across core workflows.

February 2026 monthly summary for jackstenglein/chess-dojo-scheduler: Delivered two user-centric UI enhancements improving usability, accessibility, and data entry. Implemented Date Picker Keyboard Shortcuts to prevent arrow keys from moving the board in the date editor, aligning with existing components. Replaced the progress update slider with a NumberSpinner to support increments beyond the target and ensure valid initial values. These changes reduce user friction, improve scheduling accuracy, and demonstrate consistency with existing components across the codebase.

December 2025: Delivered the Lichess .NET API Client in the lichess-org/api repository, expanding API accessibility for .NET developers. This initial client provides a native C# interface to the Lichess REST API, reducing integration friction for .NET teams. Key commit 7d9477a5a2a1e96b285e09e752c6a337647d794c implements the new client. No major bugs were reported in this cycle; remaining issues are tracked for future improvements. Business impact: expands developer reach, accelerates integration, and lays groundwork for cross-language API consumption.
