PLC Programming
Expertise in PLC programming across multiple platforms including B&R Automation Studio (C), Panasonic FPWinPro 6 (Structured Text, Function Block Diagram), and Mitsubishi (Ladder Diagram). Development of new features, functional changes, and maintainable machine code for industrial automation applications.
Industrial Automation Software Architecture
Design and implementation of configurable and reusable software libraries instead of duplicated per-customer code, resulting in fewer bugs, faster development, and a reduction of application bugs reaching production by approximately 70%.
Diagnostics & Logging
Design and coding of logging and event-traceability capabilities inside PLC applications, enabling failure reconstruction after incidents. Development of custom log-diagnostics tooling that correlates controller and PC logs on a single timeline, cutting root-cause analysis from hours to minutes.
Commissioning & Start-up
On-site start-up, debugging, factory acceptance testing, and backwards compatibility management across B&R, Panasonic, and Mitsubishi PLC platforms.
Electrical Design
Electrical design using ElCad, NX Unigraphics, PLM, and BOM automation. Standardization of electrical designs to corporate standards and 3D modeling for electrical cabinet cutout design.
Process Optimization
Optimization of cleaning tool processes and resource usage, including cutting water consumption by 50%, air consumption by 25%, and improving drying performance by 50% through PWM-controlled infrared lamps, resulting in a 10% throughput increase.
Team Leadership
Leadership of PLC, software-QA, and robotics teams with task coordination and mentoring. Introduction of clear roles and coordination structures that increased team efficiency by approximately 50%.
BOM Automation
Automated Bill-of-Materials generation using PLM, ElCad, and NX Unigraphics, cutting BOM preparation time to near zero.
Semiconductor Equipment Software
Development and commissioning of control software for semiconductor equipment including FOUP cleaning and EUV POD cleaner tools, with measurable improvements in throughput and utility consumption.
