Designed and developed a task management system with timeline-based visualization from scratch, handling design, implementation, and deployment independently
An interactive demo environment is being prepared
This demo includes horizontal timeline operations and is recommended for PC viewing. On smartphones, please refer to the screen previews below.
Main screens are available as images for easier viewing on mobile devices.
Personally designed, implemented, and deployed a task management system that visualizes tasks on a timeline for intuitive understanding of the big picture.
Not just a simple ToDo app or UI demo, but created as a "personal flagship project that functions as a complete development lifecycle" with an enterprise-system-like configuration.
Designed as an integrated approach covering backend, frontend, design, implementation, and operations, currently published as an interactive demo.
Handled all phases personally: requirements gathering, system design, backend and frontend implementation, testing, and deployment.
Continuing to verify behavior and make improvements after publishing as a demo environment.
Rather than aiming for a complete product from the start, adopted an approach of incrementally building up the minimum viable configuration that functions as a complete development lifecycle.
On the backend, prioritized business model stability over screens and appearance, emphasizing design that assumes operational aspects like concurrent operations, auditing, and restoration.
On the frontend, used "being able to grasp the entire timeline at a glance" as the most important decision criterion, designing a configuration that allows intuitive understanding of the relationship between past, present, and future with simple operations and minimal UI.
For timeline display, made not losing sight of the current position the top priority, including design decisions for scrolling and display range operations.
Ensuring data consistency assuming concurrent operations
Conflict detection through optimistic locking
Clear error handling design
Backend design assuming business models including audit logs, soft delete, and restore
UI configuration combining task management with timeline display
Row-level layout synchronization
Separation and synchronization of vertical and horizontal scrolling
Sticky element control
Designed for state consistency during concurrent operations while clearly separating frontend and backend responsibilities.
Selected code portions will be released with explanations of design decisions and implementation background.
Currently in preparation.
