Summary
Stefan Keller is a product and project development manager with 12 years of experience bringing complex electronics and optics products from concept to production, currently leading development at tatwah SA from Lausanne. Trained as a physicist at ETH Zurich, he blends hands-on engineering—firmware (C), Python automation, optics and PCB interfacing—with product strategy, IP management and customer-facing solution design. He has driven SPAD-based 3D TOF camera development and holds/invented multiple patents he helped prosecute to grant, demonstrating technical depth across hardware, firmware and regulatory domains (laser safety). Stefan pairs R&D rigor (COMSOL, measurement automation) with manufacturing pragmatism from cable assemblies to reliability qualification, and intentionally broadened his perspective through a sabbatical and rescue diver training. His profile combines a research-grade mindset with practical IP and product delivery experience, making him effective at translating advanced optics and sensor technologies into viable commercial products.
