BSc. (Hons) in Information Technology. I'm also a Geophysical Engineer and MSc in Petroleum Geoscience with strong mathematical, problem-solving, and analytical skills. I'm currently particularly interested in Data Analytics and Software Development.

Proficient in multiple programming languages, including Python, Java, JavaScript, SQL, and R. I have a huge interest in Machine Learning and Natural Language Processing. I've been recently working in areas such as Text classification and Sentiment Analysis. I have solid knowledge in several ML algorithms (Naive Bayes, Decision Trees, K-Nearest Neighbour) and in Time Series Analysis. I have experience working with Python (Pandas, NLPTK, Scikit-learn, SciPy, Plotly, TextBlob, Vader Sentiment), R, and RapidMiner.

Solid academic experience in Object-oriented programming and Web Development. I have developed several academic projects using Java, React, Node.js (Express.js), and Dash.

I also have advanced experience with the most popular flavors of Linux (Shell Scripting) and excellent academic background in Databases (SQL) and cloud computing (AWS and Google Cloud).

Work experience



IDG Direct, Ireland

Business Development Executive

  • This is a pre-sales role. I represent IDG services by making professional outgoing calls to prospective clients. I have to establish and maintain a professional conversation with IT Managers to identify their needs and next investments. The gathered information is required from our clients (Largest Tech Companies) and used in the next step of the sales process.

  • My responsibilities include: Lead Generations, Gathering client details and Maintaining/Updating IDG database with accurate client details.
  • I work in different markets and contact clients in French, English and Spanish: France, Belgium, Luxembourg, Spain, Middle East and Africa.
  • In this position, I have improved my communication skills in French and English. I have learned how to build and maintain a professional relationship with clients and improved my Active Listening Skills.
  • At IDG, I have completed a Certified Sales training. This course addressed the most important aspects of the sales process.


WikiVox, France

Web Programmer

  • I was responsible for the installation and administration of a Wiki Web Application based on the MediaWiki engine.

  • Extensive experience with the MediaWiki Engine:
  • Administration of a Linux Server:
  • Installation and configuration of a LAMP stack: Apache, MySQL, PHP.
  • Database management:
  • MySQL, PhpMyAdmin.



Simón Bolívar University - Funindes USB, Venezuela

Research geophysicist of the Parallel and Distributed Systems Group (GRyDs)

Click here to see some examples of my work in Seismic modelling.

  • As a Research Geophysicist I was responsible of ensuring the correct integration and implementation of geophysical applications into a computer cluster platform. This platform was being designed in order to facilitate task scheduling and run computation intensive tasks on clusters. One of my main activities was shell script programming for Seismic Modeling and Processing.

  • My responsibilities include:
  • Shell script / MATLAB programming for seismic data processing and modeling.
  • Task automation using Shell scripting.
  • Simulations of seismic waves propagation: Wavefront and ray tracing.
  • Generation of pre-stacked synthetic seismic data using wave propagation theories (raytracing and finite difference methods).
  • 2D/3D Seismic data processing.



CGGVeritas, Venezuela

Seismic data processing analyst

  • Demultiplexing, Reformatting (SEG -Y/SEG -D).
  • Seismic data edition: Searchin for noisy, monofrequency and incorrect polarities traces.
  • Geometrical spreading correction. Set-up of field geometry.
  • Geometry QC.
  • Application of field statics corrections, Deconvolution, trace balancing.
  • CMP sorting, Velocity analysis, Residual statics corrections.
  • NMO Correction, Muting, Stacking, Filtering.
  • Filtering: Time-variant, band-pass.
  • Post-stack/Pre-stack time and depth migration.



Simón Bolívar University, Venezuela

Academic Assistant - Earth Sciences Department

  • As a Academic Assistant, I was in charge of collaborating with the lecture by teaching some modules of the Geophysical Engineering program at Simón Bolívar University. I was usually in charge of a group between 20 and 30 students during theoretical and practical activities.

  • This experience has contributed to my professional development in two major areas:
  • By teaching modules, I have solidified many technical geophysical knowledge.
  • I have also developed communication and presentation skills, as well as the leadership strategies needed to manage a group of students and to transfer knowledge effectively.

  • Courses taught:
  • Seismic data processing: Concepts of discrete signal analysis, sampling, aliasing and discrete Fourier transform. Conventional seismic data processing sequence.
  • Seismic methods: The convolutional model of the seismic trace. Propagation and attenuation of seismic waves. Interpretation of seismic sections.
  • Seismic reservoir characterization: Relations between the acoustic impedance and the petrophysical parameters. Well-Seismic Ties. Seismic inversion and AVO.



  • Project: Evaluating the Performance of Lexicon-based and Machine Learning Sentiment Analysis for Amazon reviews classification.
