Universidad Nacional de Colombia , SICS Research Group. Lead Developer & Assistant Researcher
Website
August 2012 - November 2015
Lead a development team that built the IRTpp package for R which enables educational researchers to make analysis and get insights from exams stored in databases connected to R eg. (PISA , GRE , ICFES , etc)
R Package
- Designed and developed a architecture as a solution for the R package and the software ecosystem built by the statisticians and developers of the team./b>
- Managed workflows based in git to coordinate different code repositories across the whole team, did QA for the library code with frequent code reviews to optimize and clean the package.
- Automatized the test infrastructure to run tests across 100's of GB in SQL and no-SQL databases.
- Wrote the Data visualisation routines for the package both for user methods , documentation and reports. (ggplot2 , knitr)
- Developed and researched statistical models related to item response theory, and used them to model new methodologies to calibrate and assess the models.

Finite Element Analysis of river meanders at the Magdalena river at la Dorada, Caldas, Colombia (2012 - 2015)
This proyect had multiple stages and teams, first from GIS & Agent simulation, and later from Finite element analysis modeling of the riverbed and water, taking into account river geology. This river actually threatens the town and has caused multiple floods. The special geomorphology is hard to estimate and the numerical simulation has been of great help to enable preemptive evacuations and comprehend how to mitigate the disaster, multiple strategies of migrating towards the future are discussed, with some simulations that helped build river barriers in strategic sites implemented.
