Instrumentation Technician

Summary
Experienced instrumentation technician with over 3 years working in pharmaceutical and industrial settings. I’ve calibrated and maintained equipment like pH meters, pressure sensors, and temperature transmitters, always making sure systems run safely and accurately. I enjoy solving problems in the field, learning new tools, and helping others — including training newer techs. Recently tried a new challenge in sales and fundraising, where I strengthened my communication and customer service skills, but I’m ready to return to what I do best: hands-on work in instrumentation, troubleshooting, and validation.

3d printing, CNC and microcontrollers
I enjoy working on tech projects like 3D printing, microcontrollers, and CNC machining, which I’ve recently started exploring. One of my most detailed projects is a custom skee-ball machine that I designed and simulated using Wokwi. I integrated sensors, buttons, and scoring logic, and even have hardware ready to build it — budget has just delayed the physical build. It’s a project I’m proud of because it combines electronics, creativity, and problem-solving.
