Software developer with 10+ years of experience.

Hi, I'm a software engineer that's originally from the Chicago, Illinois. I have been developing software 10+ years and loving it. Also, I have interests in robotics, artificial intelligence, foreign languages, traveling, and the movies.

Experienced Software architect and developer, helping to make complex apps easier to navigate

I am a senior software developer (full stack), mostly working in the web for the last 20 years (I started a bit before, but in and on and off basis). During the last years I've worked mostly in Ruby (Rails, Sinatra), which I enjoy. I am highly technical and pragmatic, but I believe I can communicate effectively with both technical and non technical management. I like to keep learning (a requirement for my job, in this always changing area) and incorporating new technologies and ideas in the software I produce. During the last years I've been the technical lead, and in the last 3 years the only Senior Engineer in my team, in a scientific organization connected with NASA. I am responsible of all the applications of my department and have certain freedom to choose the tools and approaches I consider the best for my job.

Rails team member, engineering manager, everyday mentor

I am an experienced full-stack software developer with over a decade in the field, primarily in back-end development for web applications. My specialties are debugging, software design, refactoring legacy code, adding automated tests, and automating builds and deployments. I am an engineer manager with a degree in Computer Science and a Ph.D. in Artificial Intelligence.
