Christophe Grand

Nationality: French

Christophe “cgrand” Grand is a French Clojure expert and contributor who has been influential since Clojure’s early days.

He co-authored Clojure Programming (O’Reilly, 2012) and wrote important parts of Clojure itself – for example, he created clojure.walk and the initial clojure.test library, which were later adopted into Clojure core. Recently, Christophe has led ClojureDart, bringing Clojure to mobile via Flutter. From templating libraries (Enlive) to new dialects, his innovations continually expand Clojure’s reach, and he’s widely appreciated for advancing the state of the art in the community.

Carin Meier

Nationality: American

Carin Meier (aka @gigasquid) is a principal engineer at Nubank who moves fluidly between Clojure, data engineering, and AI.

She’s the author of Living Clojure (O’Reilly), a hands-on guide for learners. Carin is famous for her creative tech demos – from controlling a drone with Clojure to running neural networks – showing Clojure’s playful side. A frequent conference speaker (most recently co-presenting on AI at Conj 2024), Carin also champions diversity in tech and serves as an inspiration for women in the Clojure community. Her enthusiasm and “let’s try it” spirit embody the joy of Clojure.

Allen Rohner

Nationality: American

Allen Rohner co-founded CircleCI, one of the first CI/CD platforms, where Clojure powered the backend from the start.

A Clojure open-source contributor, Allen helped develop core.logic (logic programming) and other libraries early on. After CircleCI, he remains in fintech as co-founder/CTO of Griffin (a bank-as-a-service startup), continuing to employ Clojure to build robust financial systems. With a background in competitive programming, Allen brings algorithmic rigor to Clojure projects. His career exemplifies startup leadership that still actively commits code – leveraging Clojure’s strengths in real-world, mission-critical services.
