About me

I am a senior software engineer working at Raincode and Raincode Labs on a variety of projects regarding software modernization: on the one hand migrating software written by the client off of the mainframe, and on the other hand providing contemporary solutions for large codebases written in old (niche) languages. I mainly do a lot of source code transformation but have also have worked on making existing large software bases from the mainframe compile on Raincode compilers.

From mid 2007 to the beginning of 2017 I was a professor in software engineering at the computer science department (DCC) of the University of Chile. My research had an overall focus on easing programmers’ jobs by providing them with the right abstractions for the task at hand. I practiced what I preached so my research and teaching always was accompanied by software tools I built myself or with my students. My teaching tool was web-based and used yearly by 80+ students, other tools are open-source with public bugtrackers and use of CI infrastructure.

I specifically worked in the field of programming languages and software engineering and co-founded the Pleiad laboratory in 2007. In 2014 I co-founded the RyCh laboratory to reflect my shift in focus to software engineering for robotics.
