Professional Experience

Vivent Biosignals specializes in agricultural technology by analyzing plant biosignals to help growers detect stress, optimize growing conditions, and monitor treatment efficacy.

They use plant electrophysiology and Algorithms to enhance crop health, boost yields, and support sustainable practices. Their tools serve indoor and outdoor farmers, plant scientists, and crop developers, enabling early detection of disease and environmental stress in crops. Vivent is a BCorp-certified company with a strong focus on environmental impact and regenerative agriculture. For more details, visit Vivent Biosignals.

As the leader of software excellence and architecture, I successfully built and managed a team, developed main components, and designed the architecture, along with creating essential algorithms for our product. As part of my E-MBA’s validation, I formulated a business model centered on gamification for user retention and a technical/software strategy for the company.

I had diverse responsibilities in management, infrastructure, architecture, system administration, and algorithms, including handling IT development, server administration, and implementing algorithms in Java.

LMD is a startup developing a embeeded and a Bluetooth-based device to monitor blood pressure using a mobile phone. Our team focuses on hardware, mobile and API development, with a B2B/B2C product targeting mainstream markets.

Create a platform to facilitate networking between students and help them ‘break the ice’ by discovering common interests such as XML, image analysis, Java development, and text analysis. Facebook and other social networks were not popular in Switzerland when I did it. The startup “Poken” was heavily based on this project.

Implement CSS / HTML website based on a specific design (globalcomputing, Dr. Pearl Pu Faltings), virtual museum in VRML

I developed a 3D tracking system, similar to the motion controller of PlayStation but seven years ahead of its time. This system allowed navigation within the ‘Visible Human’ using C++, DirectX, and signal processing. It was successfully implemented in two museums, the ‘Foundation Claude Verdan’ in Lausanne and the ‘Kulturama Museum’ in Zurich, under the guidance of Professor R. D. Hersch.

The original work my project was based on.
