Iurii Rogulia's profile on Product Hunt

About

I'm Iurii — an independent engineer and fractional CTO in Finland, 20+ years building products end to end. These days I ship developer tools solo: code, billing, docs, support. vatnode.dev — EU VAT validation API. VIES is slow and unreliable; vatnode answers in under 100ms, monitors the VAT numbers you care about and webhooks you when one changes. Self-service keys and billing, no sales call. Plus vatnode-mcp, an open-source MCP server for validating VAT numbers from Claude or Cursor. htpbe.tech — "Has This PDF Been Edited?" A REST API that detects whether a signed PDF was modified after signing: 0–100 risk score with the exact evidence, in under 9 seconds. From $15/month instead of an enterprise contract.

vatnode - EU VAT Validation With Audit Evidence, Over REST JSON

vatnode wraps the EU's VIES VAT-validation system in a REST JSON API. One authenticated GET returns never-null JSON: valid/invalid, company name and address when the member state returns them, VAT-rate metadata, an optional VIES consultation number to keep as audit evidence, and a national-registry fallback when VIES is down. Coverage is EU-27 plus Northern Ireland (XI). Test-mode fixtures wire it into CI without burning real checks. Free tier is 100 checks a month, no card.

YouTube Home Blocker - Block only the YouTube feed, keep the rest usable

Open YouTube to watch one thing, lose 30 minutes to the feed? This redirects the YouTube homepage to any URL you pick (default: your Todoist Today list). Search, videos and subscriptions keep working — only the feed is gone.
