Railway Graph Polyline Editing Utility

Summary

Status

historical internal project / evolved into GraphMechanic concept

Role

initiator, concept author, developer

Stack

Type: Internal tooling / GIS data preparation / railway graph editing

Project value

A local web utility for creating, editing, and repairing railway track polylines used in railway graph data preparation.

What this demonstrates

This project demonstrates my early transition from requirements and data preparation work toward hands-on internal tooling development.

It shows the ability to:

  • identify a repetitive data preparation bottleneck;
  • convert a manual GIS/data-cleanup task into a visual tool;
  • design a pragmatic internal application for a narrow operational problem;
  • combine backend logic, map UI, routing, caching, and asynchronous interactions;
  • create tools that reduce manual work and improve data quality.

The project later evolved conceptually into GraphMechanic, a broader idea for visual graph editing and GIS-related data tooling.
