About me

My name is Longji or call me LJ if you like.

This is my personal website where I intend to publish information and progress about various projects I’m working on. The purpose of this is to easily document the projects and share my experience with others so new ideas can be inspired.

I’m a physicist and aerospace engineer with a focus in dynamic control systems and software engineering currently working on my masters while working full time. My main interests are controls systems, robotics, embedded electronics, computer algorithms, and programming. 

Aside from my core interests, I enjoy light readings about quantum mechanics, matters, and energy generations. My dream is to contribute to the creation of a new powerful energy source with my knowledge in nonlinear control systems and ultimately achieve the World Peace. 


2017 - Present

Systima Technologies

I’m a development and test engineer here and focus on design, development and demonstration of advanced technologies in support of aerospace development programs. 

2013 - 2015


I confounded this startup business which, unfortunately, is no longer in business. I worked as the principle controls engineer on multi-rotor sUAS.


Contribute to business success through aerospace engineering and software engineering, with emphasis on areas of guidance, navigation, and controls, sensor integrations, and real-time embedded systems.
