I worked on multiple programs, in several capabilities:

Software assurance for the Ames Research Center (ARC) in Moffett Field.  I developed software assurance plans in compliance with NASA and ARC requirements and reviewed the software development and testing for compliance with the requirements. The programs I worked on were:
  •	 TESS (SPOC). Software assurance of the data analysis pipeline as part of the GSFC administered TESS program. (2015 - 2018)
  •	 Aquila-II program through ARC, where the spacecraft sub-contractor was Millennium Space Systems (MSS). I wrote a software assurance plan while not being able to require MSS perform any work beyond their usual processes. The plan identified which MSS processes parallel NASA/ARC requirements, and fulfill the requirements. Aquila-II is a technology demonstrating geostationary satellite. (2013 - 2015)
  •	The Wetlab RNA SmartCycler program. Wrote a software assurance plan for a program that was using COTS software to control hardware to be used on the International Space Station. (2014 - 2015)
  •	Software assurance for the EDSN Nanosat program.  An extremely time and budge constrained program, that required tailoring of the software assurance effort. The EDSN Nanosat program was given a NASA Award for Excellent in the category of Group/Team. (2012 - 2014)

Also at ARC, Mission operations assurance for the K2 program; which is a follow-on to the Kepler program (2016 - 2018)

Consultant with SSL (formerly Space Systems/Loral). I supported the conceptual design of a polar orbiting imaging spacecraft with a co-hosted communications package. I specifically worked on the concept of operation for the attitude determination system. (2013)

Consultant with SSL (formerly Space Systems/Loral). I.supported on-going software programs for spacecraft simulation and ground support in the Systems simulation division (2011 - 2012)

Senior System Engineer
Orbital Network Engineering
https://www.linkedin.com/company/orbital-network-engineering
Supported Systems Engineering for a weather satellite, GOES-R, studying the accommodation of the Imaging instrument (the Advanced Baseline Imager or ABI) on a Northrop-Grumman spacecraft for NGST. I developed an extensive simulation of the ABI and its scan mirrors, and several proposed attitude determination methods using Kalman filters.  The simulation was used to predict the performance of the attitude determination to find which would meet the customer's requirements for the instrument pointing knowledge.  For this work, ONE was named a Gold Supplier by Northrop-Grumman Space Technology.

Supported modeling (in Matlab) FPGA firmware (written in Verilog and VHDL) used in the Orbital Network Engineering telemetry tracking receiver.

Controls subsystems engineer.  I worked on the Payload Attitude Reference System (PARS) of the Space-Based Infra-Red System (SBIRS), working on a simulation of the PARS (written in MATALB).  The PARS uses a combination of star observations through the scanner, rate information from the spacecraft, orbit information from the spacecraft, and a Kalman filter to determine where the scanner was pointed on the earth, and these were simulated to predict its performance.

I worked as a Systems Engineer on the weather satellites GOES-IJK/LM, developing flight software and "patches" to modify the flight software (on-orbit) as part of anomaly resolution.  I was given a letter of appreciation for my work as part of the flight software team from NASA's Goddard Space Flight Center, a group achievement award as part of the GOES-10 Solar Array Drive Assembly (SADA) Anomaly and Inverted Operation Group, and second group achievement award for my work on GOES.
 I worked in Controls Subsystems group on MTSAT-1R developing flight software, and in the Software Simulations Group developing a simulation of the JAMI imager used on MTSAT-1R.

        Aaron was able to troubleshoot, improve and streamline the flight software for a spacecraft program in a very thorough and yet in a timely manner to support ground testing and on orbit operations. I am very impresed by his ability to diagnose problems in software and also in hardware / software interfaces. His systematic approach is based on technical facts and his solutions are always optimal.  -  PJ Jayachandran
