Projects

Since beginning my career, I have had a chance to work on some of the great Products.

Drone Control Application (https://www.precisionhawk.com/software)

It is a software application, running on a ground-based computer, that communicates with UAV via wireless telemetry. It displays real-time data on the UAVs performance and position and can serve as a “virtual cockpit”, showing many of the same instruments that you would have if you were flying a real plane. It is used to control a UAV in flight, uploading new mission commands, setting parameters, playing back the recorded telemetry logs and caching a map.

Roles and Responsibilities :-

• Gained knowledge of Unmanned Aerial Vehicles(UAV) namely PIXHawks, Lancasters, Fixed Wings, Quad-copters and Multi-roters. Specially, their working and assembly.
• Gained complete knowledge of Mavlink Protocol used to communicate GCS with UAVs
• Implemented various Custom Mavlink messages along with Sliding window Protocol.
• Single handedly built and shipped the Project.
• Created Telemetry Log system which helps to recover the logs in case of Drone gets crashed.

Dating App

It was a dating app similar to tinder but having 4 swipes instead of 2 was its USP so on User Card it shows Compatibilty Factor which is basically a percentage tells you how compatible you could be with the other user. So, in order to calculate that I used logisctic regression.
