About Sébastien

I am an automation and optimization 'architect' developer within the Google Workspace platform to simplify users' work, gain efficiency and quality.

I provide solutions to automate manual workflows, make data and processes reliable, exchange data between different applications, and create dashboards to facilitate decision-making.

I am an expert in Google Workspace applications and their integration with other application solutions. I pay close attention to communication during the project and to design and conception to simplify the user experience in everything I produce.

Some examples of simple projects:

- Adding custom functions within Google Sheets
- Developing scripts to synchronize "pdf" type attachments from a generic mailbox to a Google Drive folder
- Synchronization between Google Sheets data and domain calendars
- Designing Google Data Studio reports

Some examples of more complex projects:

- Development of complex configurators: bill of materials calculation, price calculator with automated editing of associated documents,
- Development of Google Apps Script web apps
- Custom Gmail / Drive extension with Zoho CRM via OAuth2 protocol for authentication
- Centralized Gmail signature management solution
- Development of Google Data Studio connectors
