About

Hi, I am a senior director of data science with more than 11 years of experience in the field of data science covering a wide range of fields and methods, such statistics, machine learning, optimisation, network analysis, time-series forecasting, agent based modelling for understanding the complexities of consumer behaviour, geo-spatial data science and applications of generative AI, particularly in the development of agentic applications and tools.

Data science is not only about hard skills. Being in senior positions, I have had the experience to assist you with soft skills development and and help you navigate the complexities of career growth.

With a rich background in both line and team management, I am also deeply committed to mentoring the next generation of data scientists, having experience in mentorship programs. This role allows me to share my knowledge and experience, guiding young professionals in their career journey.

I help data scientists and analysts that would like to find their way into the field of data science and analytics and advance their technical skills and grow professionally. Also, other disciplines, like product and project managers that would like to understand the complexities of data science are also welcome for mentoring advice.

Georgios is a truly outstanding mentor. From the very beginning, his clear vision and structured approach to becoming a data scientist helped me cut through the noise and focus on what really matters. Instead of feeling overwhelmed by the thousands of things I could do, I learned to focus on a few important actions that really make a difference. Under his guidance, I revised my CV, built a stronger portfolio, and developed a habit of writing and sharing blog posts on my portfolios and data science fundamentals. As a result, my CV-to-interview conversion rate has improved significantly, and more importantly, I feel much more confident in my abilities and direction. If you're ready to put in the effort and looking for a mentor who not only gives valuable advice but also helps you take action and stay on track, I highly recommend Georgios. He genuinely cares about your growth and puts in the work to support your success. I couldn’t have asked for a better mentor on my journey to becoming a data scientist!
