FAQ
What do you need from me to start the project?
I just need access to your dataset (Excel, CSV, SQL database, or BigQuery project) and a short description of your goals — for example, what kind of report or dashboard you want to build from the data.
Do I need to install dbt or any other tool?
No, you don’t need to install anything. I deliver a ready-to-use dbt project folder or SQL scripts you can run locally, in BigQuery, or in your preferred environment.
Can you connect to Google Sheets or Excel files stored in Drive?
Yes! I can connect dbt or SQL pipelines to Google Sheets, Excel, or CSV sources stored in Google Drive or other cloud services.
What’s the difference between cleaning and modeling the data?
Data cleaning removes errors, duplicates, or inconsistencies. Data modeling goes further — it creates structured tables (stg_, dim_, fct_) optimized for analytics or dashboards like Power BI or Looker Studio.
Can you also create dashboards or reports?
Absolutely. If you need a Power BI or Looker Studio dashboard connected to your cleaned data, I can include that as an extra or part of a premium package.
Do you sign NDAs or handle confidential data?
Yes. All client data is treated as confidential and deleted after delivery. I can also sign an NDA if required before accessing any files.
Do you provide documentation or explain how to use the models?
Every delivery includes basic documentation (model diagram or readme). Full documentation (dbt docs or detailed instructions) is available as an extra service.
What if I’m not using BigQuery — can you work with MySQL or PostgreSQL?
Yes, I can adapt the dbt project or SQL transformations to MySQL, PostgreSQL, DuckDB, or any relational database you use.
Can you automate my data refresh process?
Yes, I can set up automated refreshes using dbt, Python scripts, or integration with APIs/Google Sheets, depending on your setup.
Do you offer ongoing maintenance or updates?
Definitely. I offer optional maintenance packages for updates, schema changes, or new data connections after delivery.
