My name is Divino Cesar Soares Lucas or just John Tortugo for short. I received a bachelor degree in Computer Science (2010) from the Catholic University of Goias (PUC-GO) and a Masters (2012) and PhD (2017) in Computer Science from University of Campinas (Unicamp). My main areas of interest are Programming Languages and Compilers but I'm also interested in Computer Architecture and Parallel Programming techniques.

Currently I'm a Virtual Machine Engineer at Microsoft where I research and implement techniques to make the Java Virtual Machine (OpenJDK, GRAAL) more efficient and performant.
