Companies use AI to filter candidates. I just gave candidates AI to choose companies.
Applied AI Operator with 16+ years shipping to production. After scaling and selling my phone repair business (going-concern sale, 2025) with 90% AI self-service, I now ship AI systems at scale for B2B SaaS.
🚀 What I Ship
- Agentic systems in production — multi-agent orchestration, tool calling, HITL handoff, observability
- AI-native SaaS transformation — taking B2B platforms from point-solutions to AI-native workflows
- LLMOps at scale — evals, agentic RAG, prompt injection defense, cost/latency budgets
- Production infrastructure — not demos, not POCs — systems with uptime, customers, and economic outcomes
