Speakers

Alexander Oloo (Absa Group)
I’m an engineer by trade. A designer by necessity. And a jack of all trades for fun. I love learning learning new things and debugging systems, code and people. My most rewarding job was lecturing, which for an introvert says a lot. I code for fun. I’m obsessed with screenwriting, but have no skill at it. I’m currently a Design Director where I work with a bunch of awesome humans. My primary focus is the design, analysis, and optimization of apps on the web for improved customer experiences. Oh, and I write Clojure.


Anjana Vakil (MapBox)
Anjana suffers from a debilitating case of curiosity, which led her from philosophy to English teaching to computational linguistics to software development. As Engineering Learning & Development Lead at Mapbox, she can usually be found in San Francisco; that is, when she’s not speaking at events around the world, trying to share the joy of coding and advocate for a more diverse & accessible tech industry. Ask her about the Recurse Center, Outreachy, and Mozilla!


Ben Vandgrift (Skiplist)
Ben Vandgrift struggles daily with a compulsion to solve problems. His decades-old journey has most recently led him to Clojure, allowing him to solve many software problems elegantly and efficiently. He works as a software engineer when he’s not being mauled by his rescue panther.


Bozhidar Batsov (Toptal)
Bozhidar is the maintainer of CIDER and the editor of the community Clojure style guide. Most people would probably describe him as an Emacs zealot (and they would be right). He’s also quite fond of the Lisp family of languages, functional programming in general and Clojure in particular. Believe it or not, Bozhidar has hobbies and interests outside the realm of computers, but we won’t bore with those here.


Carolina Pascale (Nubank)
I am a computer scientist and I work as a software engineer at Nubank.
I love to work with functional programming and systems design.
I have helped organising the first Rails Girls at my hometown and I have a goal to bring more women to the programming world.
My passions are: coffee, books, running and travels!


Colin Jones (8th Light)

He’s into application performance, security, DevOps, architecture, and functional programming. He is the author of the book Mastering Clojure Macros and the open-source project REPL-y, and he’s sorry `lein repl` takes longer to start than you’d probably like.


Daniel Higginbotham (Flying Machine Studios)
Daniel is the author of Clojure for the Brave and True. He cares a lot about helping people do cool stuff. Some places he’s worked include McKinsey & Company and Apple. Despite what the rumors say, he is not a lizard person.


David Chelimsky (Cognitect)
David has been designing and developing software systems for 20 years, the last 5 with Cognitect. He cut his teeth on Clojure in the financial sector, and has since threaded through e-commerce, supply chain, health care, taxes, and libraries supporting transit, transducers (ruby), and AWS APIs.
When he’s not busy thinking about better ways to write software, David can be found playing choro and samba on his cavaquinho.


Daouda Traore (Nubank)
Natural from Ivory Coast, a software engineer at Nubank since March 2019 and working to build and maintain microservices that attend common needs from engineers. Newbie in the functional programming world and impressed by Clojure effectiveness to get stuffs done.

Since being bitten by the Clojure bug a few years ago, he’s been very interested in researching applications of simple and data-driven software design to different areas of software engineering. When not staring at parentheses, he’ll often be found taking photographs outside or rock climbing.

Graduated in computer engineering by the Polytechnic School of the University of Sao Paulo, online games made me choose this path after a frustrated attempt of studying mechanical engineering.Even when taking a long time to notice software engineering as a career path for me, computers were part of my life since my childhood, when I discovered their games, started playing with their configurations and elaborating simple web pages.I am a passionate learner and one of the things I enjoy the most is sharing knowledge with other people. My hobbies include fiction books, music, games, pets and the 2000s nostalgia.
