Project: FREE DESCENT-ASCENT DEEP SEA VEHICLE- Redesigned the vehicle computer control system using modular design techniques. The computer control system was implemented in six detachable PCBs to facilitate its assembly and replacement of faulty components.- Designed a detachable acrylic frame for housing the PCBs. The frame was designed with enough room to facilitate the assembly and disassembly of the vehicle computer control system.- Designed and implemented a PWM incremental subroutine to control the burning process for releasing the ballast.Project: A MODULAR DESIGN APPROACH TO OUTCOME-BASED EMBEDDED SYSTEM EDUCATIONDesigned and implemented a laboratory teaching methodology using contemporary-electronic design techniques such as modular design.- Incorporated educational frameworks such as outcome-based education (OBE).- Developed a set of electronic modules using modular techniques and a new laboratory manual with eight laboratory practices.- Participated in the Coral Reef Ecosystem Research exploration aboard of the NOAA Ship RV Nancy Foster for nine days. During the trip, the free vehicle was deployed several times with the objective of measuring sea water properties at different depths.

- Supported the performance tuning process of one of the power management unit features that will be part of the next generation of processors. Several benchmarks tests on target processors were ran using different system configurations, and hundreds of files were processed and analyzed to identify the data flow pattern and optimize the power management feature accordingly.- Developed a set of python scripts to process and summarize benchmark results. The scripts allowed the creation and comparison of multiple processors' performance reports, achieving an exponential reduction of time during the extraction and analysis of this type of data. The time was reduced from one hour to fifteen seconds when processing a benchmark with thirty tests.- Developed a multilevel documentation system for the organizational group I was part of. The multilevel documentation consisted of two hierarchical trees related to the Intellectual Property (IP) module owned by the team. One tree was associated with the logical aspect of the IP (subIPs, power and communication interfaces, connections between internal modules and subIPs, etc.) while the other was associated with the actual physical construction of the IP (layouts, modules clusters, and subIPs).- Supported the improvement of the reliability of the RTL model developed by the team I was part of. A set of bugs (errors) were identified and fixed accordingly using industry designed flows for this purpose. The necessary changes in the RTL code and validation tests were implemented and submitted to the central repository.

Bogota D.C., Colombia

- Developed a costumer service-quality-evaluation microcontroller-based device that logs the customer evaluation on an SDcard.- Developed a microcontroller-based security system for armored cash transport car.- Designed 1 layer and 2 layers printed circuits boards with through hole and SMD components.- Programmed 8-bits Microchip microcontrollers (PIC16 and PIC18). I created software functions for using interrupts, I2C and UART protocols, timmers, and ADC.

Barranquilla, Colombia

- Developed a microcontroller-based and relay-based control systems for dumbwaiters and cargo elevators. - Developed a microcontroller-based configurable control system for elevators: 2 operation modes, 8-floor capacity, with a PC application to configure the controller variables, and a GSM monitoring system.- Repaired residential elevators out of operation.- Participated in the control system upgrade process of residential elevators.

Barranquilla, Colombia

- Designed user and technical manuals for face recognition and fingerprint devices.- Helped in the installation of face recognition and fingerprint devices.
