Experience
Pydoodler
https://github.com/jverce/pydoodlerGraphical 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.
Point-to-Point MPI Communication
I developed a test bench that demonstrates the utilization of MPI-2 in matrix multiplication. My work concentrates explicitly on point-to-point communication, incorporating one-sided and two-sided exchanges.
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.
Trycatch
https://github.com/jverce/trycatchTrycatch is a Java game that was developed as part of the Computer Engineering curricula. It was developed using the standard AWT libraries provided by the language. It is fully object-oriented and has multi-thread capabilities, which provides a great graphical experience in multi-core computers.
