I work professionally with C/C++, Python, SQL (using Postgres currently), and I've also used some C# to replicate GPS output on a Raspberry Pi.
I also am familiar with a few web languages. PHP, CSS, HTML, basic JavaScript, Node, React, and AJAX. As for shell languages, I frequently use Bash, ZSH, and occasionally Fish.
As for other frameworks, I've worked with Postgres, MySQL (database), Unity, Godot (game development), QGIS (GIS framework), ROS (robot operating system), Gtk, Qt, WinForms, Xamarin (desktop/mobile GUI dev kits), and probably a few others I am forgetting.
As for projects that I've worked on, I have the actual work I do for my job which currently entails developing autonomous robotic platforms used for radiation detection in areas deemed not safe for human traffic (military testing sites). That project I have developed the actual USB driver for the radiation detectors and the software used to configure them (backend developed purely in C++ with the frontend in C++/Qt). I also wrote up several python scripts used in conjunction with QGIS for getting survey areas created and also a GUI for the management of the actual robots. The last being the actual management of the various ROS nodes and code that controls the local network the entire system runs on (managing the robots, workstations, and server by their IP addresses).
Another current project would be the Linux distribution that I am a developer for. We are currently attempting to write an Arch installer from scratch as well as several userland tools to assist users (it's essentially a distro to give easy access to Arch without changing too much of the default Arch experience). That's currently using a good bit of Python (main language), Gtk (for the GUI frontend), Bash (for the actual backend), and Matplotlib (for a chart creation tool for partition managing).
And another project is attempting to develop a system that will help companies that work in managing iron welds (I really don't know how to explain that better). It's essentially moving their current system that is handled entirely on paper and Microsoft Excel to a dedicated server setup utilizing a Postgres database and a GUI application that is currently being prototyped in Qt/Python, but we will be more than likely moving it to C#/Xamarin.
As for my final current project, I actually try to do some work here on the forum (in addition to trying to manage this section of the forum). Xorn/Dakota will yell at me because I'm horribly inactive, but I'm hopefully going to be getting a new job by the end of the month. :)
As for other projects, I've developed a 2D Zelda clone in Godot (I can post a video of this later), a 3D "RPG", and a 3D FPS in Unity using VR. I've also developed a few startup websites that...didn't really go anywhere. And one of my personal favorites was developing a custom liquor dispensing system (similar to those Coke machines that have several flavor options). That one was done using C#/Gtk and a Raspberry Pi for its GPIO pins hooked up to some relay switches that controlled the power to some pumps. It didn't really get past the prototype stage, but it was really fun to work on.
I know I'm forgetting some stuff, but I also have a Bachelor's in Software Engineering and a Master's in Computer Science with a focus on Human Computer Interaction.
TL;DR, I'm a nerd
