Your data exists. Truly leveraging it is another story.
ERP, Excel exports, SQL databases, business tools – the information is there. But it's scattered, inconsistent, and difficult to query. And a dashboard built on shaky data is useless.
My job: transforming imperfect data into reliable and actionable decision-making tools.
Data quality isn't a technical detail – it's the foundation of everything. An LLM or an AI agent will never be better than the data it's fed.
As a project starts, I integrate this requirement: audit, validate, structure, and document data so it's usable today by your teams, and tomorrow by your AI tools.
Analytics engineer, I support SMEs and mid-sized companies at every step:
— Structuring and validating data at the source
— Modeling (dbt + BigQuery)
— Building dashboards that teams actually use
— Integrating generative AI into your business workflows, with you in the loop
