OBJECTIVE
I am interested in working in the development of real‑time embedded software. I have enjoyed a progressively responsible engineering career with NASA, Motorola, Continental AG and Navistar.
I have been responsible for the development of a variety of time critical real-time embedded applications in various fields of embedded applications, including automotive Powertrain control signals device drivers at Motorola and Continental AG and science data processing and mission critical controls for science instruments on various spaceflight platforms at NASA.
I am experienced in all phases of the software development life cycle, I have been developing software for both stand-alone embedded systems and low/mid level device drivers interfacing to high level application code; all in a CMM level 3 development environment.
EDUCATION
June 1991 Johns Hopkins University, MD
Master Science in Computer Science
May 1986 University of Puerto Rico, PR
Bachelor Science in Computer Engineering
TECHNICAL STRENGTHS
I am experienced programming 16-bit and 32-bit processors, with the ability to code in both low and high level languages, including device drivers for specialized peripherals (ASICs, time processor units, motor control units).
I am an extremely quick learner of new programming methods, tools and target hardware architectures.
I have vast experience recognizing and avoiding pitfalls of developing real‑time software (code latency, race conditions, RTOS interaction with device drivers, main processor communications with ASICs and co-processors).
I have developed software under different architectures (small interrupt‑controlled round robin scheduled applications, off‑the‑shelf and custom RTOS Operating Systems).
I am very comfortable interacting with the customer at a technical level in order to better understand requirements and their intended functionality within the complete system.
I have always been an active participant in design and code reviews and have taken advantage of them in order to disseminate knowledge of my areas of expertise and to learn other functionality within our team (communication protocols, I/O, A/D, complex timing units).
I have developed code for large real-time software architectures (> 100K lines of code), and always delivered in time and within budget.
WORK EXPERIENCE
Navistar Lisle, IL September 2010 – Present
Technical Specialist
Senior member of the recently formed Software Team.
I
am responsible for supporting various activities within the software team, including:
* developing code to support next generation fuel injection testing (provide precise timing signals to be
decoded by ASIC).
* act as a mentor to junior engineer supporting J1939 communication protocol.
*
developing Software Configuration Management Plan for use for
After-treatment ECM and as
reference for future configuration activities within the software team.
Continental AG Deer Park, IL July 2006 – Present
Senior Staff Software Engineer
Senior Technical Lead for the development of Powertrain Complex I/O drivers for automotive companies.
I am responsible for the development of time-critical Engine Position, Fueling and Ignition drivers for Powertrain applications. I have developed code for Freescale’s 32-bit MPC5500 processor (and its timing co-processor) and currently the Infineon Tricore TC1738 processor. Development includes gathering customer requirements, high and low level designs, coding, writing and executing software validation test plans, and full integration with customer application.
* I have excellent skills in gathering and interpreting requirements from customers and carrying them through the design and testing phases. Enjoy interaction with customer in order to gather knowledge of overall system architecture in order to tailor design to customer’s undocumented requirements/needs.
* In all projects I have developed test code to simulate customer’s real time application.
* I am experienced developing device drivers for precise timing applications. These
drivers include input signals processing (crankshaft, CAM) and output signals generation
(fuel,
spark, knock, PWMs) under tight timing requirements.
* I am experienced developing functions implemented at the core processor and co-processors (time processing unit on MCP5500); therefore I am skilled at identifying potential race conditions, data coherency and latency issues at the design phase.
* I have mentored junior engineers in both tools and expert knowledge.
* I am personally responsible for the development of input signal decoding function for
the crankshaft wheel input signal for Ford’s 4/6 cylinder CBPA program in order to
implement engine synchronization algorithms and to provide control and information to the
rest of the Powertrain system.
* I am personally responsible for the complete development of ignition drivers for precise
control of Ignition signals for Ford’s 4/6 cylinder CBPA program using both the main
processor and time processing unit on the MPC5500 processor.
* I am currently tasked with adapting Infineon’s Tricore 1738 processor-based worldwide
Engine Position platform software function for a North American car company’s 4
cylinder engine program, which has been identified by Continental AG as a strategic
business.
* I have developed simulation scenarios and comprehensive test plans for unit and bench
testing.
I was responsible for the development of control functions and communication drivers for a High Voltage Hybrid Control Module. Code was developed for Freescale’s 32-bit MPC5500 processor. Development includes gathering customer requirements, high and low level designs, coding, writing and executing software validation test plans, and full integration with customer application.
* Developed code for a Center Aligned PWM function, which was used to control a Motor and a Generator Control Unit. This function’s code has to be optimized to achieve a cascade of two extra control PWMs with very low latency among all three PWM signal.
* Developed CCP communications driver for use with CANape for bench test data acquisition and control
I am experienced using various test tools, including the Trace32 Lauterbach debugger
(including the PowerProbe module for precise analysis of timing signals), logic analyzers,
oscilloscopes, function generators, and other off-the-shelf and custom simulation tools.
Motorola Northbrook and Deer Park, IL May 2000 – July 2006
Staff Software Engineer
I was part of a development team tasked with implementing device drivers for automotive Powertrain time-critical device drivers (crankshaft, fueling, knock, communications protocols).
* I have developed device drivers for crankshaft, fuel injection, knock detection,
communications protocols, and ASICs) using Freescale’s MPC561 Oak processor (and its
TPU timing co-processor, when necessary).
* I have developed high level code for Task and interrupt handlers within the OSEK RTOS architecture.
* I have developed fuel and fuel/air device driver for SAAB 6 cylinder engine program.
* I inherited SAAB 6 cylinder complete Powertrain complex I/O device driver suite and was tasked with maintaining and upgrading them per various customer requests.
* I have upgraded and performed maintenance of complete Powertrain Complex I/O drivers for various GM’s 6 cylinder engine programs.
* My effort in a specific project was key in helping earning the company a cash award for delivery of customer-accepted functionality in time.

data collection from electronic peripherals, safety critical functionality for telescope
deployment, digital filtering of science data, compression algorithm and packetization of
data for transmission to the spacecraft using the 1773 protocol for data transmission
(protocol code written from scratch). Code was delivered 6 months ahead of schedule due
to a modified launch window.
