Here's some of my work in VizHub, a dataviz platform I started in 2018 to help teach courses and continue to maintain and grow as a SaaS business for professionals. The code editor in VizHub is the open source project VZCode.

Here are some videos about VizHub:

I collaborated with the amazing team at Graphicacy to visualize grant disbursements of the Kendeda Fund using a playful and creative visual metaphor of plants.

I worked on this project with the great folks at Room 302 Studio to develop this globe-based visualization of coral reefs for the Wildlife Conservation Society.

I also had the opportunity to work on this visualization of supplier diversity, which has some fun multidimensional filtering.

During my time at McKinsey I got to collaborate with an amazing team on this fairly novel visualization of Bipartisan Infrastructure Law.

I also got to work on this epic Covid-19 Mobility Dashboard within an amazing team at Stamen. There are some really neat interactions in here - drill down, linked highlighting on hover, breadcrumbs, and more!

I worked on this awesome Sankey visualization with the amazing team at @stamen back in 2018, as part of a larger academic research project on visualizing "superdiversity" in select cities.

Here's an open source piece I did for UNHCR visualizing refugees over time.

The CFI Law Database visualization shows campaign finance law in the US over time. This was my first consulting project ever, and was a great learning opportunity. This project was done in close collaboration with Seemant Kuleen.

Here are some things folks have to say about me:

Logan Williams
Data science lead at Bellingcat
LinkedIn

"Curran is the most systematic thinker of data visualizations that I have met — his perspective will change the way you think about representing data and give you practical tools for exploring your ideas."

Andy Davies
Design Principal, The London Stock Exchange
LinkedIn

"Curran has a wonderful, enthusiastic, optimistic and dedicated approach to everything he does which is infectious. He is incredibly knowledgable - probably underplaying his capabilities - in all things based around front end dataviz development. Always keen to experiment and explore new ways of working with the wider team creating an inclusive and collaborative environment which is sometimes lacking from wider project / product teams.

Curran is also one of the best teachers I have had in terms of explaining front end complexity. He has a natural ability to match your level of knowledge and then work with you to understand the nuances that just make something click. I learnt I lot in our time together, even recording training sessions where I could ask questions, not really understand, but play back later.

It was honestly a pleasure to work with him and I can't recommend him highly enough. I'll also add my total collaboration was remote and in different timezones, making this doubly impressive. On the occasion we did meet, it was like meeting an old friend. Just hire him / work with him / get on a call with him, you'll see."

Mike Ahern
Director, Academic & Corporate Engagement + Adjunct Instructor, Worcester Polytechnic Institute
LinkedIn

"Curran Kelleher has taught graduate level courses in data visualization. He can produce great work and teach others to do so too!"

Louis Parizeau
Co-Founder, Highgate Analytics
LinkedIn

"Curran quickly understood my complex codebase, and was able to fix many of my visualization's bugs that I couldn't find solutions for online. Additionally, he gave specific, best-practice advice to improve the load time, UI responsiveness, and maintainability of my D3 implementation. Curran was great to work with and I would 100% recommend him to anyone stuck with D3 bugs, or looking to refactor their code to follow best practices."

Lucio Biase
Founder, Thunnus Tech
LinkedIn

"Curran is experienced, creative, humorous and very knowledgeable. We needed to jumpstart our development of the manipulation of data visualization and he was one of three experts we could find globally. Tired of iterations and delays flew up to sit with him. He was initially incredulous of having a new client look over his shoulder for a week but true to character he was open minded. Strangers became colleagues and became fast friends, the week flew by and not only was the work product fantastic so was his openness and willingness to empower our tech team."

Ben Brophy
Web Developer at Ninety | Former HubSpot
LinkedIn

"Curran is a data visualization wizard - just check out his body of work! He taught me everything I know about D3 and data viz."
