Jeff Ralston

Developer and Linux/Unix systems administrator. I build scrapers, monitors, and data pipelines, and I maintain the infrastructure behind them.

Engineering

  • Python, TypeScript, Node, Bun. Postgres, Redis, MongoDB, SQLite.
  • Shipped production projects including an AI agent framework, a media analysis tool, and a voice AI assistant.
  • Scraping specifics: headless browsers, proxy rotation, resilient retry and backoff, diff-based change detection.

Operations

  • Linux administration: server builds, hardening, monitoring, automation. I keep things running after a target site ships a redesign.

Background

  • Independent security researcher.
  • U.S. Marine Corps veteran (1998–2010), data systems.

On Apify Narrow, dependable Actors that answer one question: what changed? Price, inventory, listing, and posting monitors built for public business data, consumable by scripts and AI agents.
