My principal Open-Source contribution to the public centers around the thermalvis repository. In addition, I have made this into a ROS Package so it can serve the demands of the robotics community more effectively.
You can read more about the thermalvis repository here.
I also have a stackechange profile, but have interacted with the site to accumulate many "reputation" points. I've developed more reputation with my ROS Answers account. You can check out my GitHub and Bitbucket accounts too if interested.
