Diagnose and optimize Railway server for n8n
Ivan was phenomenal to work with. He jumped in immediately, diagnosed my n8n / PostgreSQL storage issue, tuned pruning and vacuum settings, and drafted a clear optimization plan that cut both disk usage and monthly costs. Communication was fast and detailed, and he patiently explained each change so I could learn from it. Delivered exactly what I needed, ahead of schedule, and went the extra mile. Highly recommended!
