Developer
2015 - 2021
Geomodelr
- Worked as the main developer and the CEO of Geomodelr. Geomodelr is the first platform where you can create a geological model from start to finish without leaving your browser.
- Developed the entire platform from an algorithm that converts any set of 2D geological information into a 3D model.
- Created a very fast kernel for geological modeling in C++ with Python bindings. It uses boost geometrical libraries to make millions of queries per second.
- Developed the back-end application in Django, using technologies like Django REST Framework and Celery; used PostGIS, GDAL, and other geographical and numerical libraries.
- Built the front end using React, Bootstrap, HTML, and CSS.
- Constructed interactive visualizations in 2D using D3.js and in 3D using Three.js.

Developer
2019 - 2020
Learning Seeds
- Developed the application from scratch to help educators of children with special needs.
- Managed the services in Elastic Beanstalk and AWS.
- Created the back end in Python with Django and a RESTful API. Used PostgreSQL as the database.
- Built the front end as an SPA with TypeScript, React, and Redux. Enabled printing the report in PDF with several images and text that needed to fit precisely on the PDF pages.
Technologies: TypeScript, Redux, React, JavaScript, Django, Python, PDF
C++ Developer
2018 - 2020
Confidential
- Created an advanced application for geometrical processing in C++ that loaded into a device with limited capabilities. Used geometrical algorithms and optimized the performance and results.
- Worked on Windows and Visual Studio C++ using local and remote development.
- Handled specific hardware with given capabilities to obtain the best possible outcome from the device.

Researcher
2014 - 2014
INEUR
- Built the infrastructure for the INEUR computer vision platform using Autoconf, Travis CI, Ansible, and Docker.
- Maintained the servers in Microsoft Azure and used scripts to automatically scale the number of servers to accommodate the visual processing.
- Helped develop the C++ OpenCV code people detection code.
- Maintained the Python Django application that served as the front end to the OpenCV back end.
- Created analytics algorithms using R and the Microsoft Azure platform.
Technologies: R, OpenCV, Docker, Django, Python, C++

Experience
Geomodelr
https://www.youtube.com/watch?v=pDbns0AWOZsThe first web geological modeling platform. Geomodelr allows people to create geological models without leaving their browsers. It enables the integration of well and point data, the creation of 2D maps and sections, and the generation of 3D models.
Damian Par
https://repository.eafit.edu.co/handle/10784/5045Damian Par is a Fortran parallel code that can simulate earthquakes in thousands of computing nodes. It can generate distributed meshes in memory with billions of nodes, as well as produce graphical representations and query-specific data from the simulations.
Gabriel Constrained Delaunay Triangulations
http://cadcamcae.eafit.edu.co/documents/chapter_book_Adv_Tech_2009.pdfI used several levels of the Gabriel Graph to constrain a Delaunay Triangulation in 3D—making it possible to create the most complex surfaces that bound objects perfectly, even the ones with several holes or complex geometry.
Learning Seeds
https://www.learningseeds.com/softwareA website to manage educators and students with special needs. The website was created in Django and deployed with AWS Elastic Beanstalk. It has a RESTful API and a PostgreSQL back-end. It can also export several graphics and text perfectly to PDF multipage files.
