Thinks in systems and trade-offs

Based on a real case: Email automation using Google Apps Script

Case Example: Email Automation

Problem

Manual email creation (~2–3 min per email)

Solution

• Draft-based generation via GAS
• Structured input using Google Sheets

Result

• Reduced to <30 sec per email
• Enabled batch processing (30–50 emails/session)

Trade-off

• Not fully automated
• Chose flexibility and human validation over speed
