Über Elouan
Data consultant based in Zurich, with 7 years of experience. I step in where data actually needs to be useful: bringing structure back to messy setups, automating what should be automated, making numbers reliable, and delivering tools that help instead of adding more layers of complexity.
I work across the full chain: transformation, exploitation, visualization, and automation. In concrete terms, I can both clean up a shaky data flow, structure business logic, build solid reporting, and deliver dashboards or automated processes that save hours of manual work.
I favor simple, robust solutions that can be used quickly. The goal is not to sell a gas factory or make the client dependent on me. The goal is to put in place a system that holds up, that teams understand, and that keeps running properly over time.
Yes, AI can already speed up part of this work. I use it myself. But in real-life business settings, you still need someone who can tell when it is producing nonsense, fix the logic, secure the output, and connect everything back to actual business reality. That is where I bring value.
Tools: SQL, Python, Power BI, Tableau, Alteryx.
