November 2009 to September 2010: Undergraduate Research Assistant, Center

for Space Exploration Technology Research, University of Texas at El Paso,

El Paso TX

Participate at a NASA Group 5 University Research Center fostering new

aerospace science and technology concepts. Assist in the research and

development of high performance micro-propulsion technologies in order to

benefit next generation micro-spacecraft and microsatellite missions.

. RD&T Undergraduate team leader focusing on a Methane Test Rig

simulating a regenerative cooling rocket engine.

. Collaborated with RD&T Graduate team to design cryogenic feed system

for university's first rocket test bunker.

. Handpicked by program director to conduct a

manufacturability/reliability study involving the fabrication of

miniature cold-gas rocket nozzles.

. Selected for White Sands Test Facility tour after successful

completion of spacecraft propulsion coursework.

September 2006 to May 2009: Design CNC Production Engineer, Helmy

Associates, San Antonio TX

Design thin and thick gauge plastic vacuum and pressure formed parts using

Autodesk Mechanical Desktop 2009 and Rhinoceros 4.0. Design and fabricate

prototype and production patterns and dies for in-line and single station

thermoforming machinery. Responsible for the programming, g-code editing,

setup and operation of 3 and 5 axis CNC machine tools for cutting mold

tools, trim fixtures and part trim paths.

Eliminated a costly, time consuming manual process by developing a reliable

and repeatable CNC method for the micro drilling of deep (15x diameter)

vacuum holes in aluminum mold tools.

Implemented new mold engraving method allowing for custom embossed logos

and stylized lettering on formed parts.

Established Standard Operation Procedure (SOP) documentation for entire

thermoforming machinery fleet with an emphasis on safety, new operator

training, and optimal production quality and speed.

Improved fixture reliability allowing for machine maximum cutting feeds,

longer tool life, smoother finishes and the largest single block mold sizes

in the company inventory.

Diagnosed and repaired CNC and in-line thermoformer issues (recalibration,

axis parameter reprogramming, faulty servo replacement, CNC/ g-code server

networking) in-house saving on specialized labor costs and minimizing

machine down time.

Created all line drawings with specified callouts used in two separate U.S.

patent applications.

August 2004 to December 2005: Machine Shop Technician / Practicum TA,

Washington University, St Louis MO.

Designed, fabricated, and modified parts for university research

laboratories involving precision manual and CNC machine processes.

Responsible for the instruction and assistance of undergraduate students

in classroom and laboratory settings with a focus on machine clamping

strategies, speeds and feeds, as well as techniques for utilizing manual

mills and lathes.

Handpicked to build a precision electronics housing for government laser

vibrometer research using manual mill machine.

Instructed fellow technicians on self-taught conversational programming

methods for mechanical engineering department's first vertical CNC mill.

Handpicked from 10 student shop technicians to be a teaching assistant for

the machine shop practicum course after demonstrating continued efficient

and accurate use of the machine shop tools in the production of specialized

laboratory testing equipment.

Received special recognition from Mechanical Engineering Dept. Senior

Lecturer for late night machine shop mentoring to the Fall 2005 senior

design students.

May 2005 to September 2005: Director's Assistant, Center for Air Pollution

and Trend Analysis, St Louis MO.

Responsible for processing and archiving raw data collected online from air

quality monitoring stations throughout the globe. Researched and

implemented online instructional multimedia for web based atmospheric data

analysis tools. Maintained and upgraded company computers as needed for

security and optimal performance.

Researched and implemented new software for the rapid conversion of

existing web presentations for viewing across multiple internet browsers

without need for the end user to install a third party plug-in.

Produced unique instructional media incorporating fluid screen captured

movies, narration, and interactive quizzes increasing the number of visits

to the web based trend analysis tools.

August 2004 to December 2005: Machine Group Leader, Formula Society of

Automotive Engineers, St Louis MO.

Responsible for the project management of parts machined in-house for

competition race vehicle. Approved machinability of parts made in-house,

acquired raw materials, supervised machine shop crew and consulted on

vehicle part optimization.

Leadership role in vehicle testing and performance optimization.

Vehicle placed in top third overall and 19th in acceleration tests at

national competition.
