Justin Johnson — Applied AI Engineer

I build agents that operate software with no API.

About

I'm Justin — an Applied AI Engineer at Pinger who ships autonomous systems that actually run in production, not just demos. I build agents that operate software which has no API: multi-agent RAG architectures, self-monitoring mobile testing bots, desktop and GUI automation fleets, and legal document extraction pipelines that replaced weeks of manual work with minutes of machine precision. Background in biomedical engineering (VCU) and three years in technical support learning what breaks and why.

  • 6+ production AI agents
  • 50–60% handling time cut
  • 50+ staff trained on AI
  • 96%+ extraction accuracy
