Developed high fidelity simulation of the voly C50 aircraft in MATLAB/Simulink. The simulation includes both the VTOL flight and fixed wing flight. The simulation is further integrated in a software in the loop environment where the flight software is running with developed dynamics.

Developed customized version of total energy controller in the Simulink.

Modeled and developed ground effect of the aircraft to resolve landing issue.

Developed and patented vertical delivery system. The system allows automatic handling of payload packages after aircraft drops the payload.

Developed precision landing system for the abovementioned delivery system. Aircraft can land on the intended landing platform within 0.5 meter.

ROS2 integration of companion computer with flight controller. This includes ROS2 messaging communications with flight controller.

Work on development of flight software of VTOL aircraft.

Ship to ship delivery:

Developed guidance algorithm and system for VTOL payload delivery from land to boat, from boat to boat, and from boat to land. The system allows aircraft to land on a moving boat in sea state 2. This system is demonstrated with US naval demonstration on USNS Burlington.

Developed vision estimation of the moving landing target using extended kalman filter.

Performed flight testing of the developed system in the field. Developed flight analysis tools and perform flight analysis after flight testing.

I work on online education website for students from Kindergarden to 12 grade. The website allows students to learn and practice the questions meticulously designed by experience curriculum designer.

I work on:

Handful of random questions generation logic for Math, English & Language Art, Spanish using Java.

Design and implement Front-end user facing interactive components using React. These are used by students on different PC browsers and mobile app and browsers.

Design and implement new user facing administrator management web application using full-stack tools, and integrate with existing SQL data models. The tool is designed to accommodate around 100k students school district size administrator account.

Implement pricing management internal tool using struts and Java. This manages how price is calculated based on different products customer subscribed.

Upgrade the old email system to new email system.

Implement infrastructure for question generations.
