Accelerate your Business with AI and Technology Leadership
On-demand CTO services: AI, Software, Hardware
A seasoned CTO as a Service
I offer you maximum impact
I’m Marc Pastre, a passionate technology expert with 25 years of experience, both in Industry and Research. As an enthusiastic CTO, I lead multidisciplinary engineering teams to cutting-edge innovation and top-notch performance.
I am at the same time a high-level technology strategist, and a hands-on expert architect and engineer in Artificial Intelligence, software engineering and electronics.
As an insatiable learner and motivating teacher and leader, I love building the best tech with the best teams in the most complex and demanding environments. Give me challenges, I’ll offer you solutions.
I started my technology and innovation journey as a researcher and lecturer at EPFL, in software engineering and microelectronics.
I then served as a CTO in different environments (corporate groups, SMB, startup) and industries (medical, aerospace, consumer software / hardware, industrial, food). Leading multidisciplinary teams of engineers in software, electronics and mechanical engineering is where I excel.
I have 10 years of experience in developing AI solutions for vision, audio and signal processing, business intelligence and multimodal GPTs. I encapsulated AI systems in the cloud (SaaS), servers & PCs, and IoTs (microcontroller, FPGA).
Today, I am developing hands-on, leading and coaching developers for AI, full stack (front end and back end), cloud, mobile applications, in most modern programming languages.
I’m based in Geneva, Switzerland, but can help you remotely as well. In English, French, German, Swiss-German, or Spanish!
