Agentic Engineering & Building Open-Source AI Agent Toolkits

Peter (steipete) is a Vienna and London-based polyagentmorous builder, former founder of PSPDFKit, and current team member at OpenAI working on agents. He stewards OpenClaw, an open and independent AI agent ecosystem, while actively developing a suite of local-first crawlers, native macOS automation tools, and developer utilities.
