Majoring in Computer science and engineering

I have been working with computers and various electronics for more than 16 years. I am experienced with electronic prototyping (general robotics such as MCU automation control), python programming, and CAD (fusion 360). I also have experience in many other fields regarding electronics, and some basic machining. I have built devices ranging from touch screen interfaces to small satellite prototypes. Of my skills, I prefer to program with python.

Certificate of U.S. Congressional Recognition (#2) - Award of Excellence from NASA and California Space Grant Consortium 2018 (#2) These were given to me upon my second year of interning for NASA. This year we lead independent research on improving the design of the Hall effect thruster. We begin the initial phase of development on this project, and are continuing on for another year. In the initial phase, we confirmed the principles of the hall effect thruster by accelerating particles of a choice fuel source, creating a small amount of force that, after further refinement, can propel satellites in space. The image provided shows all the certificates received so far for 2017, and 2018.

I developed a web scraper for a client, and he was happy enough to provide me with a testimonial video of how his experience was during our time working together.

I wrote an application using Python and Kivy (for GUI ). This application allows a user to log a member of a some facility using a barcode scanner. It also allows for manual entry if the customer forgets their membership cards. The manual entry function allows search by first, and last name as well as last visit and customer ID (if they have that on hand some how). The scan by barcode logs customers in less than a second, and the search function takes approximately 2-3 seconds, with user interaction, to find and log a customer. Customers can be added through the search button, or by right clicking and selecting the drop down option to add customer.

Award of Excellence for completing the Microcomputers and Robotics intership from NASA space grant consortium. I spent 7 months, and over 1000 hours developing computer models, circuits, programming and operating CNC machines. We are seeking to publish our research within a few months, and hope to have our satellite launched by 2018.

Driver

Pizza hut
1월 2011 - 8월 2020 (9 , 7 )
I currently drive at pizza hut while I attend my local College. I cook, clean, wash dishes, take out the trash, sweep and mop, answer phones, cash out customers, maintain and make repairs around the building, install computer/electronic related items (including POS's, camera systems, and other related items) in addition to my typical driver duties. *Update - This location closed its doors as of August of 2020 due to covid-19 based financial issues and I no longer have a job here.*

Thermogenics Lab Internship

College of the Desert
1월 2020 - 5월 2020 (4 , 1 )
We researched the properties of different types of water ice and how they pose risks as for potential landing sites. Unfortunately the thermogenics lab has been placed under lockdown due to its location on a school site. We will continue our work, when safe, by testing and recording the unique properties of ice samples under compressive loads. This data will be used to create mathematical models for computer simulations of environments containing the various water ices.

My role on the team was chief engineer. During our time, we were tasked with designing a rover that could scan for important resources and retrieve them autonomously. I oversaw the team, and guided them in the design, construction and programming of our rover. Our rover was able to detect different mineral resources through optical spectrometry. I was awarded Most Valuable Player for our team, but I would like to acknowledge our success as a result of every team mates hard work.

Congressional Award of Recognition

United State Congress
2019
Out of 1,500 students that applied, my proposal was accepted and I was granted the opportunity to be in the first graduating class of NASA's Community Aerospace Space Scholar Program for College of the Desert. I worked with a team of great people, where my role was chief engineer. I oversaw the entire design/build process for our automated rover. The rover performed successful mineral identification through the process of optical spectrometry. I was awarded my third Congressional Recognition.

Award of Congressional Recogntion

During this internship we developed a working model of a particle accelerator. The model was used to demonstrate the concepts of Hall effect thrusters used on small satellites. We ionized particles of sublimed iodine and demonstrated it's charged state by subjecting it to magnetic fields. We found significantly greater concentrations of solidified iodine crystals in the vicinity of the magnetic fields versus anywhere else in the chamber. This resulted in my second U.S. Congressional recognition.
