My research interest has led me to develop advanced R, Python, and C++ skills. My GitHub profile showcases my open-source projects, predominantly focused on gravity estimation, data wrangling in R, and data visualization using Shiny. More details can be found in the Open Source section.
Additionally, I maintain a blog ( pacha.dev/blog), where I post various notes and tutorials. Some highlights include “Creating LaTeX Figures with Inkscape”, “A Crash Course on PostgreSQL for R Users”, and “A Step-by-Step Guide to Write an R Package that Uses C++ Code (Ubuntu)”. These posts reflect my ongoing commitment to both learning and sharing knowledge in the field.
I offer R and Shiny consultancy services on Fiverr.
Trivia: My blog post Comparing SQLite, DuckDB and Arrow with UN Trade Data made it to the top ten on Hacker News.
Having time-financial margin to maintain and expand my R packages.

pachadotdev/capybara
tldr; If you have a 2-4GB dataset and you need to estimate a (generalized) linear model with a large number of fixed effects, this package is for you.
R 13 -
pachadotdev/cpp11armadillo
The idea is to pass matrices/vectors from R to C++, write pure C++/Armadillo code for the computation, and then export the result back to R with the proper data structures.
C++ 6 -
pachadotdev/open-redatam
Recover information of REDATAM databases for statistical analysis using standard tools such as SPSS, STATA, R, etc.
