PROFILE
Arun Chandanaveli
Over a two-month period, this developer enhanced the mermaid-js/mermaid repository by introducing and refining datastore flowchart support. They built a dedicated datastore shape with alias handling, leveraging D3.js and SVG manipulation to deliver sketch-like visuals using rough.js. Their work included updating documentation and ensuring API clarity, while also addressing rendering inconsistencies to improve diagram readability. In the following month, they refactored the rendering pipeline to better handle user node overrides and bounding box calculations for hand-drawn styles, increasing diagram fidelity and stability. The implementation relied on TypeScript and front end development skills to strengthen production reliability.
