Title

Mechatronic Systems Engineering Student

Looking for a 6-month mandatory internship from April 2027 · Germany

Bio

Mechatronic Systems Engineering student with project experience in mechanical design, electronics and embedded programming. In university projects, I have designed mechanical assemblies and electronic circuits, worked with sensors and microcontrollers, and evaluated designs through simulation.

I am particularly interested in machine development, automation and how mechanical, electrical and control systems work together. I enjoy figuring out how things work and take a structured approach to solving problems. In international teams, I explain technical decisions clearly, listen to different ideas and take responsibility for meeting shared deadlines.

Planet Locator

A standalone, offline device that lights an LED for every planet above the horizon. A GPS receiver gives position and time; an ESP32-C3 computes each planet's azimuth and elevation and shows them on an OLED display. Custom PCB in KiCad with USB-C charging.
