I'm David! Here is my resume. I'm a senior at Universidad de los Andes studying Systems and Computing Engineering.

I really enjoy solving problems and the beauty of a good explanation. I think that is why I love to teach anything I know. For know, I mostly teach Mathematics, Physics and Computer Programming.

I also believe that we, who understand technology and push it forward, should work to improve the world, not make it worse. Let everything we do be transparent and full of goodness. Protect people and their rights; Do not take advantage.

What I know and have worked with

The programming language I know better is Java

Currently learning

This semester I am taking courses on Geostatistics, Scientific Programming and also a course called Capitalism, History and Culture. Of course, I am also doing my thesis with John Guerra, oen of the best professors I have encountered. Best semester ever!


My thesis: PhotoRing

My thesis advisor is John Guerra, an amazing professor and person.

My goal is to design and implement an architecture that will support an scalable visualization and exploration tool for large image datasets. You can see my proposal here.


localstores iOS localstores Android

Mobile App that helps students find the closest stores with the best prices for their shopping lists. We used Swift, Google Maps API and Firestore. Project made with Daniel, Camilo and Juan. It was great working with these guys who I now consider grea friends. You can see the slides of the final presentation here. This was my first serious encounter with agile methodologies and the result was an awesome product.

Accio Planner

We want students who are having a hard time paying for college to have a better educational experience. We can help them with our course planner, which allows them to make better decisions.

Essentially, we created a web App that merges 2 or more majors/minors optimizing for time given the student constraints, in order to take much more advantage of the college experience. We used NodeJS, Express, GAMS, Angular, PostgreSQL.

You can see a working demo here, which is the same video from aboce. Also, this is the paper we wrote here.

Project made with Maria Camila, Laura and Juan. Together we are ACCIO.


well col front page

Application for storing information and monitoring emergencies a petroleum wells network.

The main objective for this project was to implement client requirements taking into account quality attributes such as usability, performance, reliability, and security.

We made use of load balancers such as Nginx in order to guarantee availability and also applied design patters such as Factory Method and Proxy to reach the desired levels of coupling and cohesion in the source code.

In addition, we implemented an API that allowed communication with real sensors measuring data using NodeRED.

Technologies used: NodeJS, Express, PostreSQL and Angular. We developed a client for Android and iOS.

Project made with Juan José, Juan and Sebastián.



Application for storage, management and analysis of a port network. The application was able to handle many types of transactions regarding the multiple agents in a port such as: customers, ships, containers, workers, employees, employers, traders, etc.

At the end of the project our database had tables with more than 2 million rows. All this data was proccesed and worked by the implementation of a efficent database schema that used good design and indexes to make faster searches and also efficient in memory algorithms when necessary

We also exposed all of this functionalities through a RESTFUL API.

Technologies used: Oracle11g, Java JDBC, SQLDeveloper.


CCT map

Application for finding shortest/cheapest/ routes for package delivery in Bogotá, Colombia using shortest path, Dijkstra and other graph algorithms.

The program saved the most efficient route in a file and also was able to draw it upon Google Maps

In order to increase the efficiency of our program we reimplemented the algorithms usind redundancy of data structures to make the operations as efficient as possible. Of course, we traded space for time complexity. This resulted in our program being at least 10x faster than other applications for certain searches.

This application was made using pure Java.

My life at Uniandes

Right now I am taking the following courses:
  • Capitalism, History and Culture: My last elective and one which has given me a different view of the world and how it came to be what it is now.
  • Geostatistics: I am learning about spatial data analysis and geostatistical methods. More specifically: semivariogram analysis, kriging interpolation and model evaluation through cross-validation techniques.
  • Scientific Programming: Cool biomedical course focused on numerical methods to solve science and engineering problems.

CS Graduate courses:

  • Cryptography: Graduate level foundation on traditional cryptography, principles of cryptoanalysis, secret key ciphers, key agreements, authentication protocols, digital signatures and public key ciphers. Professor Milton Quiroga is awesome and I can sincerely say this is one of the best courses I've taken. To see the type of things we do: Shamir's secret sharing scheme.
  • Secure Infrastructure: The course revolves around the components of an infrastructure solution: services and applications, processing, operating systems and communications. For each of these components, the respective risks and the corresponding controls that can be implemented are analyzed.
  • Scientific Computing and Visualization: More info here. Together with Juan Murillo we wrote an small paper.

Uniandes courses are full of teamwork and projects, here are some of the CS undergraduate courses I have taken:

  • Object Oriented Programming I & II: A cool introduction to programming, algorithms and data structures in Java
  • Data Structures
  • Design and Analysis of Algorithms: I learned about language semantics, algorithm construction, strategies, optimal route graph algorithms, Greedy algorithms, Search within graphs and the basics of computational complexity theory.
  • Web development: Using React, HTML, CSS, MongoDB, Node and sometimes Meteor to build cool web applications such as kipcount. Learn more here
  • Business Intelligence: Using data science methods and tools to obtain valuable insights. Did an analysis about cellphone theft here in Colombia and also one about computer room usage at Uniandes.
  • Technological Infrastructure
  • Computer Infrastructure
  • Networking
  • Software Architecture: The purpose of this course is to develop skills in the areas of software design and architecture, relying on methodological tools such as architecture styles, patterns (eg, design, architecture). Likewise, the aim is to develop the ability to use and understand the impact of technology on software architecture.
  • Software Development in Teams
  • Transactional Systems (Databases): I learned really useful concepts that I have used practically every semester since I took the course.
  • Modeling, Simluation and Optimization: Check this paper.

Other awesome courses I have taken:

  • Probability and Statistics
  • Finance: Deciding to invest
  • Ethical Dilemas
  • Physics I & II: Mechanics, Thermodynamics and Electromagnetism
  • Great Ideas in Physics
  • Differential, Integral Calculus and Differential Equations, Linear Algebra, Vector Calculus

Some things I've lived during college!

2014 Fall
I began college at the University of the Andes in the second semester thanks to MINTIC scholarship
2014 Fall - 2015 Spring
I really enjoyed my first 2 programming classes: Object Oriented Programming and Algorithms I and II. I got the best grade in both of them and learned a lot!
2015 Spring
I was teacher Assistant for the Discrete Mathematics course here at Uniandes. It was great to teach and help students just like in highschool!
2015 Spring
Programming Teacher at Cupitaller ! The place where students come to learn about OOP in Java Programming Teacher at Cupitaller! The place where students come to learn about OOP in Java
My both hard and enlightning encounter with indian philosophy
2015 Fall
Learned Data Structures and completely loved them. At the end I built app to calculate shortest paths of delivery for a company in Bogotá, Colombia.
2016 Spring
Took Transactional Systems, where I learned how to integrate a database with millions of entries with an application for managing operations in a real-worls port. Also I took Software Development in Teams where I learned the importance and value of automating testing and deployment together with good team organization practices.
2016 Summer
Took Introduction to DevOps by Microsoft of edx. During the spring semester I realized that delivering software is not as simple as you might think. You need continuous integration of the people involved in the project. The thing is, this is not achieved easily, you need a culture and tools to support that culture. DevOps is one of the solutions to that.
2016 Fall
Software Arquitecture is here! Learned about Security, performance, avaliability and usability. Modern design patters and arquitectures used in the biggest companies were practiced in labs and in the class project: wellcol.
2017 Spring
