Rockstar🎓
Top SchoolJohn Peterson is a pragmatic full-stack engineer and founder with five years of experience building production-grade Python and JavaScript systems across startups and enterprise environments. He has progressed from engineering roles at KPMG and Globality—where he led platform rearchitectures, built OpenAPI generators, and shipped LLM-driven analytics and conversational tools—to founding and CTO roles in early-stage companies and Antler-backed ventures. Comfortable leading small teams and shipping end-to-end features, he combines hands-on coding (FastAPI, LangChain-style tooling, CI integrations) with product-minded systems thinking to reduce developer friction and improve operational stability. A repeat founder and YC-affiliated early engineer, he brings startup grit and a practical focus on automation and tooling that accelerates delivery.
