I help production sites turn their process data into tangible gains: more performance and less wasted energy.

Process & Energy Engineer (HES) with ~7 years of field experience in energy and processes — including the operation and optimization of a heavy industrial plant — I also code in Python. This dual expertise makes the difference: most data analysts don't know the process, and most engineers don't know how to leverage data. I love both.

Specifically, I collect your existing data — historian, SCADA, machine exports, even if messy — I clean it, structure it, and extract actionable analyses: performance monitoring, drift detection, quantified gain levers. And because I understand process as well as data, I go beyond just pretty dashboards: I help you identify real opportunities at the production and energy levels.

My tools: Python (Pandas, time series), data analysis, data visualization (Plotly, Streamlit), thermal & energy optimization.

Let's talk — I enjoy concrete topics and hands-on work.
