About Me Hello! I’m a Data Scientist passionate about combining data, AI, and analytics to solve real-world business challenges.

Get to know me!

Hi, I’m Vasilis Katsikas, a Data Scientist based in Athens, Greece, passionate about combining data, AI, and analytics to solve real-world business challenges. I currently work at rapidbounce, a leading digital transformation agency specializing in the hospitality and tourism industry.

My work bridges the worlds of data science and marketing technology, designing predictive models, automating data pipelines, and delivering insights that drive revenue optimization and smarter decision-making for hotels and brands.

I’m also pursuing an M.Sc. in Data Science & Machine Learning at the Hellenic Open University, building on my earlier training at Big Blue Data Academy. This continuous learning journey keeps me at the forefront of emerging trends in AI, ML, and business intelligence.

My go-to tools include Python, Pandas, SQL, Looker Studio, and Google Cloud Platform (GCP). I use them to build scalable solutions, from predictive analytics and dashboard automation to AI-driven content generation.

Beyond the code, I’m passionate about using data to tell stories, inspire change, and empower people to make better decisions. Let’s connect and explore how data and AI can shape the future, one insight at a time. 🚀
