Athanasios Kyritsis, PhD

Machine Learning Expert and Software Engineer · Lausanne Metropolitan Area, Switzerland · [email protected]

I am an experienced Computer Scientist specialized in Machine Learning. For the past 5 years, I have worked on several Machine Learning projects and trained numerous models, including Neural Networks. I have experience with end-to-end AI workflows, from data collection and preprocessing, to training machine learning models and deploying to production. I am a passionate developer with a keen interest in web and mobile technologies. I have been designing and developing Android applications and backend APIs, both professionally and as a hobby. Apart from making machines learn, I also never stop learning.

Interests

Apart from being a computer engineer, I enjoy most of my time being outdoors. In the winter, I enjoy skiing around the Geneva region. During the warmer months, I enjoy biking and kayaking on the lake.

When forced indoors, I enjoy reading books, I practice for my next music concert, I am an aspiring chef, and I spend my free time exploring the latest technology advancements and trends.

I love traveling around the globe! I have already been to a few dozen countries, and I look forward to visiting more.
