I build production AI agents and the backends that run them LangGraph multi-agent systems and scalable APIs in NodeJS, NestJS & Django. Every project delivered at 5 stars. Most backend developers can wire up CRUD and call an LLM API. Fewer can design agentic systems that hold up in production with real state management, tool use, human-in-the-loop fallbacks, and clean architecture underneath. That’s where I focus. 🤖 AI & Agent Engineering • LangGraph multi-agent systems state machines, branching, human-in-the-loop • LangChain workflows & RAG pipelines • CRM and business-process automation powered by AI agents • Agents wired into real production backends, not just demos ⚙️ Backend Engineering • REST APIs clean, modular, scalable architecture • Auth & role-based authorization (JWT, OAuth, Kinde) • Database design & query optimization (PostgreSQL, MongoDB, MySQL) • Redis caching, WebSockets / Socket IO, real-time systems • Payment integrations (Stripe, Paystack, Flutterwave) ⭐ Recent work • Built and shipped a LangGraph agent system rated 5 stars. Client: “delivered beyond expectation… broke down the tasks, executed to timeline, delivered an excellent solution.” • Architected a custom CRM for a LangGraph product (NestJS, Redis, WebSockets / Socket IO) also rated 5 stars. 🧠 Stack TypeScript · JavaScript · Python | NodeJS · NestJS · Express · Django | LangGraph · LangChain | PostgreSQL · MongoDB · MySQL | Redis · Docker If you’re building an AI agent, an automation system, or a backend that has to handle real business logic not just basic CRUD let’s talk.
