Summary
🤩
Rockstar🎓
Top SchoolTobias Graf is a maintenance and automation technician with nine years of hands-on experience in industrial machinery upkeep and process improvement, currently serving as Maschinentechniker Instandhalter at Bosch Rexroth in the Stuttgart region. He has a practical background as a service technician and electrician at Homag and BITZER, and played a leading role in introducing TPM and participating in KVP teams to boost production reliability. Trained as a certified automation technician with a mechatronics focus, he blends mechatronic, robotic and automation expertise with shop-floor problem solving. Tobias also contributes to embedded and IoT open-source projects—working on Matter (connectedhomeip) resource monitoring clusters and adding device support and stability fixes to OpenZWave—bringing firmware-level insight into industrial settings. His mix of production TPM leadership and low-level embedded development gives him an uncommon ability to bridge operational maintenance and connected-device engineering. Colleagues value him for practical innovations that reduce downtime and for translating field issues into durable technical solutions.
