How much does a freelance data analyst cost in French-speaking Switzerland?
Fixed-price per project or time-and-materials at a daily rate, depending on scope. An initial scoping workshop sets the budget and priorities before any commitment.
Data analyst or data scientist: what is the difference?
A data analyst turns your existing data into KPIs and decisions (reporting, dashboards, analysis). A data scientist builds predictive models. Here the focus is on immediate decision value and automation, predictive models included when the need justifies it.
Do you work on-site in Geneva or Lausanne?
Projects are run mainly remotely, with occasional on-site visits possible in Geneva, Lausanne and the Lake Geneva area for scoping workshops or key milestones.
Which data and AI tools do you use?
On the data side: Power BI, Looker, SQL, Python and dbt for reporting and pipelines. On the AI side: LLMs, RAG and automation orchestrators (n8n, Make) integrated with your existing tools.
Can we start with a one-off engagement?
Yes. A data audit, a dashboard or an AI automation proof of concept often makes a good first milestone, before a broader engagement if the results follow.
Can you clean up a poorly structured Excel or CSV export?
Yes: inconsistent columns, duplicates, mixed dates and formats, empty cells, all of it is reworked and made reliable. The deliverable is a clean, documented file, along with reusable cleaning rules for your future exports.
