I'm a Data Science Professor using the R programming language at the University of Costa Rica; I'm also a demographic researcher dedicated to algorithms for optimization and analysis through simulations to get population projections.
Among my primary skills is process automation through the R language, database cleansing, bayesian statistics, classification models, correlation analysis, R package development, population projections, time Series analysis, exploratory data analysis, survey analysis, generalized linear models (regression analysis), structural equation models (SEM), parallel processing, simulations, visualizations, multivariate statistical analysis, and more.

Cesar is a highly skilled professional. His work was delivered on time and with high quality, he explained me every step of the project clearly. I recommend Cesar for any type of work/project related with programming and statistics.
Cesar is a real gem. he knows what he is doing and provides very valuable insights and ideas for the whole analysis. Communication is very easy with him. I would 1000 % work with him again!
I have to admit that I am not a fan of R, and I explained things also bad with complicated data collections. Working with this guy after one day, then I feel more comfortable with R. He not also listened very patiently my bad explanations but also coded with me. I highly recommend him and hope that we will collaborate next time if we have a chance.
Statistical analysis, software and programming languages such as R, Python and Git. Versatility for process automatization through specialized algorithms, analytics and mathematical skills.
