Don't let this gap widen
Without intermediate PostgreSQL mastery, your queries slow down by 50% in production, generating frustrations and revenue losses: an e-shop loses 20k€/month due to excessive loading times.
Poorly managed transactions cause 5% data errors, exposing you to costly GDPR audits (10k€ fines).
Ignoring JSONB blocks data-driven innovations, while faulty backups risk 24h downtimes (cost 5k€/h).
Train in 7 hours to avoid endless debugging, gain 30% productivity, and secure your critical apps starting tomorrow.
