Experience
Georg Fischer JRG AG
Production Engineer / Foundry Expert · Sissach, Switzerland
- ▸ Root-cause analysis of CHF 5M+ metallurgical defect via DoE, SEM, and EDX — transitioned QA from subjective visual testing to a measurable, data-driven process.
- ▸ Conceptualized full replacement project for core foundry machinery and designed an AMR-based automated core-shop modernization.
- ▸ Implemented 5S and Shopfloor Management principles; improved lead times for high-runner products by ~30% via Kanban.
- ▸ Defined the DFM review process for new product introduction and corrected false cost models in SAP.
- ▸ Responsible for plant-wide data management, analysis, and foundry safety planning.
Funke GmbH
Technical Director / Head of Foundry · Alfeld, Germany
- ▸ Led quality management implementation to achieve AS9100 aerospace certification, opening a new high-value market segment.
- ▸ Improved yield on all new products by ≥50% and reduced chill usage by 60% through redesigned casting concept process.
- ▸ Reduced prototype production effort by 80% via 3D printed molds — lead times under 5 days for finished, machined prototypes.
- ▸ Solved critical Magnesium casting defects by redefining grain refinement and heat treatment processes.
- ▸ Provided direct design support to Rimac for next-generation electric engine components.
Nemak Wernigerode GmbH
Senior Project Engineer · Wernigerode, Germany
- ▸ Rescued a critical engine block project near SOP — resolved hot tearing root cause with process parameter adjustments alone, avoiding costly tooling changes.
- ▸ Built a SQL-based framework for leveraging process data across the entire manufacturing chain.
- ▸ Analyzed 18 months of prototyping data (10,000+ tensile bars) to develop a Minitab predictive tool for material properties.
- ▸ Led 3D printing integration for novel casting concepts in highly optimized engine water jackets.
Componenta
Product Development Engineer · Helsinki, Finland
- ▸ Reduced foundry scrap rates by 50% in a 6-month project using simulation and process data analysis.
- ▸ Identified root cause of unexplainable microstructure defect in new-generation ductile irons (GJS-600-10).
- ▸ Developed modular 3D printed prototype system deployable on a standard manufacturing line.
- ▸ Designed a casting simulation data framework that reduced required transfer volumes by several orders of magnitude.
