Hello there. I'm
Leandro Collares
I create web-based visualizations that tell stories and help different audiences make sense of data. I'm looking for opportunities to assist organizations in their data visualization challenges.
About Me
I design and implement interactive visualizations to tell data stories or help individuals explore data in novel ways. By using UX research methods, I help organizations understand people's behaviours, needs and motivations. I am experienced in training, supporting and mentoring people of diverse backgrounds in different contexts as well.
Here are a few frameworks, libraries and tools I've been working with:
- JavaScript
- GeoJSON/TopoJSON
- D3
- Plotly
- Svelte
- Folium
- Vue
- Pandas
- React
- Axios
- SVG
- Lodash
