System & Integration Software Test Engineer
Medical Devices · Embedded Systems · HW/SW/Mech · Infrastructure

I work at the intersection of software, embedded electronics, and system integration, with hands-on experience ranging from hardware and mechanical rework to automated testing, backend services, and infrastructure.

My background is rooted in embedded electronics and hardware design, and I progressively expanded toward software development, test automation, and cloud-native infrastructure, particularly in regulated and research-driven environments.

A system-level and integration-focused role spanning software, hardware, and mechanical aspects of medical devices.

• Requirement-based, integration, and system-level testing
• Automated test benches for embedded systems and backend APIs
• Quality, reliability, and performance testing on real devices
• Log analysis, mocking, fault injection, and reporting
• Mechanical rework and adjustment of devices during validation phases
• Close collaboration with firmware, hardware, mechanical, and quality teams

• Designed a 2-layer PCB in Altium for automated test benches
• Assembled electronics boards, connectors, and casings
• Debugged ADC boards, power supplies, and SPI buses
• Designed experiments to optimize gluing and assembly processes
• 3D design with SolidWorks and rapid prototyping
• Integrated electronics into textiles and sportswear

Innosuisse Project — Real-Time Volumetric Data Compression

• Developed C++ software for real-time compression of volumetric data
• Performance- and constraint-driven design in collaboration with industry

JPEG DNA — Research & Standardization Project

• Worked on the verification model of the JPEG DNA standard
• Implemented a software compression engine for DNA-based image storage
