Project details
🤝 Please read the terms below carefully to avoid misunderstandings and to ensure we meet the deadlines and respect our time.
WHEN THIS SERVICE IS RIGHT FOR YOU
🌟 This service is perfect for HTML to PDF generation using tools like wicked_pdf or wkhtmltopdf in Ruby on Rails
⚠️ Requires an existing single Ruby method as the data source (e.g., Invoice.find(invoice_id))
PROPOSE A CONTRACT INSTEAD IF
Your project requires:
💾 Data preparation or collection
📚 Multiple charts or combining data sources
✍️ Handcrafted PDFs from scratch (e.g., using prawn)
UNIFORM DATA STRUCTURE
If you need PDF for invoices and report, then you need to order this service twice, because it's twice a work.
If you need both the "monthly" and "daily report," they most likely use the same data structure, and this service covers that case.
SERVICE TIERS
🟢 Tier 1
Basic formatting:
• page size/orientation, headings
• addon placed as is
🔵 Tier 2
Advanced styling:
• page header, clickable links, text markup and transformation, table styling
• RoR assets images injection (logo, icons)
• addon styling
🟣 Tier 3
Add & style images uploaded with ActiveStorage, Carrierwave, Paperclip, local files

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!
