Worked on the PMKS-Web/PMKS-Refactor repository, delivering features and fixes that improved simulation accuracy, UI reliability, and data accessibility for mechanism analysis. Developed a unified unit system and enhanced static force analysis, using Angular and TypeScript to ensure consistent unit handling and per-joint force display. Addressed complex issues in physics simulation by refining center of mass calculations and force alignment, leveraging mathematical techniques and robust state management. Improved frontend-backend integration with new API endpoints for torque and reaction force data, while stabilizing user interactions through targeted bug fixes in SVG grid zoom and data parsing, supporting reliable engineering workflows.

Mar 1, 2026Summary for 2026-03 (PMKS-Web/PMKS-Refactor): The month focused on delivering accurate mechanism analytics and improving data accessibility for faster, more reliable decision-making. Key features delivered include: 1) Center of Mass (COM) Calculation Enhancement: implemented Circles Intersection Technique to improve COM tracking accuracy across sub-mechanisms in analysis-solver.service, addressing previous inaccuracies and enabling more reliable physics analysis. 2) Torque and Reaction Force Data Accessibility: introduced a backend API to retrieve the last analysis results for a specified sub-mechanism and integrated frontend retrieval to display calculated torque and reaction force data, streamlining data availability for UI dashboards. 3) Logging Refactor in AnalysisSolveService: migrated logging statements to template literals for improved readability and consistency, aiding debugging and maintenance. Major bugs fixed: Corrected COM calculation logic responsible for inaccuracies by adopting Circles Intersection Technique, and stabilized data exposure by formalizing the API and frontend data retrieval pipeline, reducing data fetch errors in UI. Overall impact and accomplishments: Achieved higher simulation accuracy for mechanism analytics, faster and more reliable data presentation in the frontend, and improved maintainability through clearer logging and API design. Demonstrated capabilities across backend API design, frontend integration, and mathematical computation techniques, delivering business value through dependable analytics and actionable insights. Technologies/skills demonstrated: TypeScript-based service development (analysis-solver.service), backend API design and integration, frontend data retrieval workflows, Circles Intersection Technique for COM calculation, and modern logging practices (template literals).

Oct 1, 2025Month 2025-10 summary: Focused on stabilizing the joint editing experience and deployment reliability in PMKS-Web/PMKS-Refactor. Delivered three top-priority fixes: 1) angle handling and synchronization across joint-edit-panel and link-edit-panel with normalization between degrees and radians, preventing NG0100 errors; 2) joint name input binding fix in joint-edit-panel by switching to [value] binding and corrected event handling; 3) build constraint threshold adjustment in angular.json to avoid hosting build failures due to size limits. These changes improved UI accuracy, reduced runtime errors, and improved deployment stability.
