Peter Šutarík

I'm Peter — a web-analytics and marketing-measurement consultant from Slovakia who spends the other half of his time building data products. I've been in the measurement business for 15+ years: if it can be tracked, scored, or ranked, I've probably built a pipeline for it.

🛰️ Sonar  — ASO keyword intelligence for indie iOS developers: keyword rankings, real Apple-sourced search popularity, difficulty scores, competitor tracking, review analysis, and an MCP server for AI agents.

My actors here are built on the same production infrastructure that powers Sonar — the data they return is what the tool itself runs on, not a weekend scrape.

Most ASO tools estimate keyword popularity from autocomplete order — a proxy. Sonar surfaces Apple's own Search Popularity signal, the same one Apple shows advertisers. That's the data behind my actors' popularity scores.

TypeScript / Node.js, PostgreSQL, and an unhealthy number of scheduled jobs. Everything I ship runs unattended in production — reliability over demos.
