I've developed a variety of skills over the past decade that I've been interest, involving mechanical, electrical, and software engineering, and more disciplines.

Several years' experience using SolidWorks and Fusion 360, especially for additive manufacturing, as well as manual machining and other processes.
Experience in a multitude of languages, including Arduino/C++, Python, MATLAB, Excel, Assembly, and SQL.
Proficient in the use of Excel, Word, SharePoint, Power Automate for documentation, process tracking, experimental/technical communication, etc.
Operation, assembly, and maintenance of different machines; Especially strong skillset with 3D printers. Exposure to CNC routers, laser cutters, as well as pick and place machines.
Experience using manual lathes and mills. Taught by a variety of instructors, students, and others. I am endlessly fascinated by the art of manual milling.
Setup and maintenance of self-hosted services on Pi's or old computers, revitalized as Linux servers.
Exposure to producing carbon fiber and fiberglass composite parts using the pre-preg and vacuum bagging process.
Experience joining many types of components, such as wire-wire, through-hole pcb's, SMD components (iron or hot air). Other forms include infrared oven & solder-mask, and copper-pipe.
More than a dozen hours' experience with GTAW with steel and aluminum. Exposure to other welding techniques such as Oxy-Acetylene and GMAW.
I've built and flown several multirotors (3-6 blade), and many model airplanes. Besides recreational flying, I also have experience with aerial photography using a DJI Mavic 2 Pro.
