What I Do

Data Engineer & Data Science

My background in banking and finance, combined with hands-on experience in data engineering, enables me not only to understand the business context behind data-driven solutions but also to effectively apply advanced technologies like Machine Learning and AI in real-world scenarios to optimize processes, extract insights, and support data-informed decision-making.

Projects

My current interests focus on MLOps, Machine Learning, Deep Learning, and building reliable RAG pipelines. I am also highly interested in blockchain technologies and their intersection with data engineering and quantitative trading.

Leisure

In my free time, I enjoy being outdoors, hiking in the mountains, and swimming in the lake. I also like reading technical books on MLOps, data engineering, AI, and blockchain.
