AI Agent & LLM Automation Developer | React, Next.js, FastAPI, AWS

I build AI-powered products end-to-end: LLM agents, RAG systems, chatbots, and workflow automation — shipped on React/Next.js, FastAPI, and AWS. Top Rated Plus, 10 completed contracts, $88k+ earned. I specialize in AI integration, agentic systems, MCP/tool integration, LLM APIs (OpenAI, Anthropic), and RAG, combining them with strong backend architecture and cloud engineering to build AI capabilities that work reliably in real-world production environments. I build modern platforms using FastAPI, React/Next.js, and AWS, with AI integrated as a first-class capability for automation, intelligent workflows, search, document processing, and complex business operations. My approach is pragmatic: clean architecture, clear data flows, production-ready AI integrations, and systems designed to scale and remain maintainable. 🚀 Have an AI idea, PoC, or MCP that needs to become a production-ready product? I can help turn it into a scalable system — from architecture and AI integration to cloud deployment and production delivery.
