Electronics Engineer

Dausinger + Giesen GmbH

Designs and develops new high-precision analog/digital PCBs for laser control systems using Eagle and KiCad.
Leads hardware testing, failure analysis, and systems integration for all PCBs within high-power laser systems.
Conducts component-level debugging on PCBs, tracing faults from power supply rails to communication lines (CAN, SPI) and sensor data (ADC/DAC).
Identifies burned/damaged components, performs SMD/THT rework and soldering to repair and validate boards.
Developed an advanced auto-alignment algorithm using Particle Swarm Optimization (PSO) and PID control in Embedded C. This firmware uses a 4-Quadrant-Diode (4QD) PCB’s ADC signals to control piezo mirrors, automatically maximizing the laser’s power position.
Developed an Autonomous Laser Alignment System using a PIC18F26K83. Implemented a Bayesian Optimization algorithm to maximize optical power by controlling a 2-axis piezo inertia mirror mount.
Designed a "Virtual Encoder" in software to track position for an open-loop system.
Configured the Internal ADCC in Burst Average Mode to filter high-impedance photodiode noise.
Interfaced with a PI E-870.41 driver using a custom 20kHz multiplexed pulse train.
Developed a robust CAN Bootloader for the dual-core dsPIC33CH, enabling remote firmware updates. Solved deep-level bugs related to hardware timer conflicts, slave core fuse-bit mismatches, and CAN state management.
Installs and integrates validated PCBs into the final laser systems, verifying all CAN, power, and I/O cabling and debugging any system-level hardware/software conflicts.
Contributes to the development of the C++/Qt-based system control software, integrating CAN protocols to control and test all PCBs from a unified application.
