Agentic Systems Has built AI agents, skills, tools, or MCP (Model Context Protocol) integrations

Python Proficient for backend development

Secondary Language Working knowledge of Go, TypeScript, or Rust

Cloud Infrastructure Deep experience with AWS/GCP/Azure — cost optimization, compute decisions, not just deployment
