Experience

  • Pydoodler
    https://github.com/jverce/pydoodler

    Graphical software developed in Python used to create and store simple color drawings. This is one of the many projects that I developed as a Computer Engineering student. The app is fully object-oriented. It was developed using the Pygame framework.

  • Test Bench Generator

    The product of this project is a Perl script that automates the generation of test benches for formal verification of digital designs. This achieved an improvement in efficiency that allowed the company to save approximately 1 year of testing. The company was able to achieve a great time-to-market with a bug-free design.

  • Research Project (MPI-2)

    As a final project for my Computer Engineering degree, I concentrated my efforts on investigating the performance and development impact that one-sided communication has in distributed MPI-2 applications when the underlying network technology is InfiniBand. The comparison was done against two-sided communication.
