Golfredo Perez Fernandez

I’m a Senior Full-Stack AI Engineer focused on agentic AI systems, RAG workflows, multi-agent orchestration, and production-grade TypeScript applications. I specialize in building AI-powered products that go beyond simple chatbot integrations: agents with tool calling, retrieval, memory, structured outputs, streaming interfaces, database-backed tools, PDF/code tools, and workflow automation. My strongest stack is TypeScript, Qwik/Qwik City, React, Node.js, LangChain/LangGraph-style architectures, OpenAI APIs, Turso/libSQL, Drizzle ORM, Docker, Fly.io, and Vercel. I have several years of experience owning products end-to-end: architecture, frontend, backend, APIs, database design, integrations, deployment, debugging, and iteration with users. I’ve built educational AI assistants, internal agents, property advisors, Web3 dashboards, QR/NFC attendance systems, tokenized property marketplace flows, and 3D/VRM AI learning experiences. My work is especially useful for companies that want to turn complex workflows into reliable AI products: customer support agents, internal copilots, research assistants, document-based RAG systems, sales/demand-gen automation, AI dashboards, and product-facing LLM features. I’m looking for a remote full-time, contract, or freelance role where I can help a startup or product team ship practical AI systems quickly. I work well in async-first teams, communicate clearly, and enjoy taking ownership from ambiguous idea to production.
