As a Usability Engineer at SEBA Hydrometry, I focus on improving the user experience of advanced hydrometric systems through a rigorous, research-driven, and user-centered approach. My work combines usability analysis, qualitative research, interface design, and hands-on prototyping to enhance the overall product experience for professional users in technical environments. Within a long-term product development initiative, I conducted a detailed usability evaluation of the NetLogCom data collector, using cognitive walkthroughs and expert interviews to uncover key usability challenges. I translated these findings into a high-fidelity interactive prototype designed in Figma, incorporating UX best practices and intuitive UI structures. To assess the redesign, I planned and conducted comparative usability testing with domain experts. The results showed that the prototype significantly outperformed the original interface in all core UX dimensions—effectiveness, efficiency, and user satisfaction—according to established metrics. These improvements led to clear, quantifiable value for the business, reducing user errors, shortening training times, and boosting operator confidence in critical field operations. This role allows me to synthesize my skills in UX research, qualitative methods, data analysis, UI design, and cross-functional collaboration, delivering strategic design outcomes that support SEBA’s mission to provide reliable and user-friendly measurement technology.

At photrack AG, a pioneer in non-contact water monitoring technology, I contributed in supporting the configuration and optimization of our proprietary software platform DLab, designed to deliver reliable, scalable, and affordable environmental monitoring solutions for global water management. My responsibilities included the technical setup and calibration of hydrological monitoring stations for a range of national clients. This required in-depth familiarity with both the highly complex DLab system and the environmental science behind real-world monitoring applications. I engaged directly with customers, providing tailored configurations and ensuring the system met their data acquisition and reporting needs—both remotely and in close coordination with the field teams. To enhance usability and accessibility, I led the complete UX-driven redesign of the DLab user manual, integrating clear structure, visual guidance, and accessibility principles. I also collaborated closely with software developers and researchers to align platform functionality with user expectations, and contributed to iterative usability improvements that increased operational efficiency and reduced onboarding effort. Through this role, I combined systematic analysis, technical communication, and user-centered thinking in a highly interdisciplinary context—gaining deep insights into environmental technology, applied hydrology, and the evolving challenges of sustainable water resource management.

As a System Analyst at SEBA Hydrometrie, I was responsible for ensuring the quality, reliability, and precision of core components used in advanced environmental monitoring systems. My daily work involved testing and calibrating measurement hardware under structured lab conditions, using clearly defined protocols to maintain high standards in sensor performance and long-term stability. Working closely with engineering teams, I supported the continuous refinement of field-ready technology, ensuring that each component met strict requirements for accuracy and durability in real-world hydrological and meteorological applications. This role strengthened my ability to work with technical systems hands-on while maintaining a strong focus on analytical rigor, quality assurance, and interdisciplinary teamwork in a high-stakes, real-world context.

As a Studio Assistant at MONOM, an internationally renowned spatial sound studio, I supported the technical and creative operations within a cutting-edge, four-dimensional immersive audio environment. My responsibilities included assisting with live performance setups, providing on-site support to artists during production sessions, and ensuring the smooth operation of the studio’s high-end equipment. This role deepened my understanding of spatial audio technologies, immersive sound design, and the logistics behind real-time audio performance. I developed a hands-on perspective on studio workflows, gained technical confidence in working with sophisticated hardware setups, and learned how to contribute effectively in high-pressure, collaborative creative environments.
