Work History

Honeywell Aerospace

Torrance, CA

06.2021 - Current

Documented products and processes using Siemens NX and Teamcenter to document release notes and designs.
Checked design compliance with product specifications and standards requirements.
Completed model and drawing changes for multiple MVCS programs.
Created a sharepoint site to house all MSC/EPS NX design guide files.
Helped develop a new Vapor Cycle Compressors section in the Honeywell Aerospace Design Standards Handbook.

Honeywell Aerospace

06.2020 - 08.2020

Queued CARs stalled in response phase thus increasing proper response time from 60% to 80% and created standard work document for this process.
Proactively mass updated over 20,000 QIRs before their impending expiration date and created standard work document for this process.
Updated Serial Profiles to mitigate duplicate serial numbers for and created standard work document for this process.
Conducted two in depth MRB analyses and reviewed and updated pre-existing standard work document for this process

Hawai'i Space Flight Laboratory (HSFL)

Honolulu, Hawaii

05.2019 - 08.2019

Used Solidworks to design base plate for Linkstar communications box, used for mainland field tests of duplex and simplex radios.
Used Solidworks to design basket for ultrasonic cleaner, in order to clean and prep hardware to enter HSFL clean room.
Conducted, and wrote SOP for, Solar Panel tests.
Conducted analysis of TVAC data in order to gain better understanding of HSFL thermal chamber behavior while ramping up to hot temperatures and down to cold temperatures.
Managed hardware during Neutron-1 integration.
Used Solidworks to adjust design of Neutron-1 four-cornered stand in order to prevent mechanical failure of separation switches.
Used Solidworks to conduct radiation simulations to predict behavior of satellite bus when subjected to ramp up/down in thermal vacuum chamber.
Used Solidworks to design copper thermal strapping to heat sink electronic boards to rails of Neutron-1 satellite.

USC Rocket Propulsion Laboratory (RPL)

08.2017 - 05.2021

Successfully launched and recovered TRAVELER IV, world's first entirely student-designed and fabricated rocket past the Karman line.
Successfully constructed six propellant grains lined with linen phenolic casting tubes.
Manufactured a total of 180.4 lbm of propellant, thus providing 4,275lbf (vac) of thrust to the TRAVELER III and TRAVELER IV vehicles.
Successfully integrated the entire linen phenolic stack into the carbon fiber motor case which is lined with an EPDM rubber insulator.
Completed nozzle layup, consisting of a carbon-phenolic exit cone to provide thermal protection and a graphite insert to maintain throat diameter and motor performance.
Assembled two igniters, each wired with 3 electrical matches in parallel for redundancy, and composed of 4:1 mix of solid composite propellant and BKNO3.
Used Siemens NX to design a new nozzle, nozzle mold tooling, combustion chamber, and injection plate for our proposed liquid vehicle
