What I'm looking for

I’m looking for teams that ship production agentic AI and automation—where I can design backend integrations, enforce safety (human-in-the-loop, least privilege, rate limiting), and build reliable orchestration and data pipelines.

I’m a Staff-level platform engineer and backend/integration expert with 20+ years across distributed systems and enterprise architecture, currently focused on production-grade agentic AI infrastructure. I build n8n automation platforms, deploy MCP server integrations, and orchestrate self-hosted LLM runtimes with Ollama—always with safety patterns like human-in-the-loop controls and least-privilege access.

From designing Docker-based microservices on self-managed VPS to implementing structured data extraction pipelines with Playwright and Firecrawl, I turn frontier AI tooling into reliable operational workflows. I also bring deep legacy platform credibility from 18+ years at IBM, and I’m actively building Bitcoin-aligned technical infrastructure for the Bitcoin ecosystem.
