Profile, the short version.

Est. 2022 · Dublin, IE
Jigar Patel

I turn data into decisions, and occasionally into pictures of galaxies.

Trained as a physicist, retrained as a data analyst. I care about clarity, correctness, and speed to insight. My work spans interactive dashboards, statistical modelling, ML experiments, and an open-source library I maintain for chart-lovers.

  1. 01 Maintaining echartsy (v0.7.4) . Pandas-native fluent builder for Apache ECharts: 19 chart types, three render targets (Jupyter, Streamlit, browser). Latest release added six color palettes and five style presets.
  2. 02 Reading . Thinking in Systems (Meadows) and Gaia DR4 release notes.
  3. 03 Photographing . Narrow-band emission nebulae from Dublin's backyard skies.

Let's make something clearly seen.
