Freelancer profile translated to English.
Back to original languageAbout Bertrand
- I help Data, Analytics, and BI teams improve their skills in SQL and BigQuery on GCP through practical, cost- and performance-oriented training.
- I offer a 3-day (21-hour) SQL on BigQuery training course, designed for groups of up to 10 participants, available in-person or remotely via video conference.
- The goal: to make teams autonomous, more efficient, and in control of their BigQuery costs.
Training Content
The training covers, among other things:
- Standard SQL and BigQuery specifics
- Performance and cost optimization
- Partitioning, clustering, and best practices
- Analytics and BI use cases
Teaching Approach
The training is based on a fictional flagship project, inspired by realistic business issues (retail, sales, customers, performance, costs).
This approach allows for coherent progression over the 3 days and immediate application in a business context.
Adaptability
The content is adaptable to the participants' level and the company's challenges (Data Engineering, Analytics, BI).
A price reduction may be offered for training multiple groups within the same organization.
