Yuvrajsinh Jadav

Full-stack and AI engineer with 3.5 years of building and running complete products: React and Next.js frontends, React Native apps, Node.js and Python backends, and agentic AI systems built with LangGraph, LangChain, Claude and MCP, using tool calling, structured outputs, RAG and human approval gates. I built a field-service platform used by 3,700+ customers and 220+ technicians, replaced a 25,000-row Excel payroll process with idempotent automation, and ran its CI/CD for 22+ months. I also shipped a LangGraph and Claude document pipeline to production, and put a React Native marketplace on the App Store after clearing a review rejection. On my own platform, Trevion, I run a 24-role system of headless Claude agents that has merged 105+ pull requests, protected by an auto-reverting regression gate and human-only merges. Day to day I build with Claude Code, Codex and Cursor, and deliver complete features with tests. Based in India, available immediately, and comfortable overlapping with US or UK hours.
