🏆 Top 1% on Upwork I design and build AI MVPs powered by LLM agents, RAG pipelines, and API-driven automation for startups and SaaS products. From internal workflow automation to customer-facing AI features, I help founders quickly validate AI ideas with scalable backend systems and full-stack applications built in Python, Node.js, and Next.js. –––––––––––––––––– 🔹 WHAT I BUILD ✔ AI Agent MVPs (OpenAI, Claude, Llama, Assistants API, LangGraph, AutoGen) ✔ RAG Prototypes (Pinecone, Neo4j, hybrid search, NeMo Guardrails) ✔ API & SaaS Automation Workflows ✔ Backend Systems (Python, FastAPI, async workflows, pipelines) ✔ Full-stack AI apps (Node.js + Next.js) ✔ Evaluation & Testing setups for LLM reliability –––––––––––––––––– 🔹 WHY CLIENTS HIRE ME I’m an entrepreneur — not just a developer. I think in terms of: • Speed to validation • Investor-ready demos • Product-market fit experiments • Scalable foundations without overengineering • Cost-efficient inference I don’t just connect an LLM to a UI. I turn AI concepts into working products founders can test, demo, and iterate on. –––––––––––––––––– 🔹 BACKGROUND • 10+ years in data science and engineering • 4,000+ hours of hands-on LLM and prompt engineering • Built AI systems across legal, real estate, research, marketing, and automation domains • Taught AI and prompt engineering concepts to 6,000+ professionals If you're building an AI product or automating your business and need to move fast — let's build it right.
