AI Engineer | LLMs, RAG, AI Agents | React, Python Looking for an engineer who can build your complete AI-powered product not just the frontend, backend, or AI layer? I design and build production-ready AI applications from concept to deployment, combining modern full-stack engineering with LLMs, agentic workflows, and scalable cloud infrastructure. Whether you're launching a new AI SaaS platform, integrating AI into an existing product, or building an internal automation system, I deliver solutions that are reliable, maintainable, and built for real users. I work across the entire product lifecycle—from architecture and UI to backend services, AI integration, deployment, and ongoing optimization—so you can work with one engineer who understands the complete system. What I Build * AI SaaS platforms powered by GPT, Claude, Gemini, and other LLMs * AI Agents using LangGraph, CrewAI, MCP, and tool-calling workflows * RAG applications with semantic search, document intelligence, AI copilots, and vector databases * Voice AI and conversational applications using Whisper, ElevenLabs, Deepgram, and Twilio * Modern web applications using React, Next.js, TypeScript, Node.js, FastAPI, and PostgreSQL * Cross-platform mobile applications with React Native and Expo * Workflow automation and data pipelines using n8n, Playwright, Puppeteer, and third-party APIs * Multi-tenant SaaS platforms, dashboards, marketplaces, booking systems, CRM, ERP, and custom business applications Core Technologies Frontend React, Next.js, TypeScript, React Native, Expo, Tailwind CSS Backend Python, FastAPI, Node.js, Express.js, PostgreSQL, MongoDB, Redis AI & Machine Learning OpenAI, Claude, Gemini, LangChain, LangGraph, CrewAI, MCP, RAG, AI Agents, Pinecone, pgvector, Qdrant, Chroma Infrastructure Docker, AWS, Linux, GitHub Actions, CI/CD Why Clients Work With Me - End-to-end ownership—from product architecture to production deployment Strong full-stack engineering combined with practical AI implementation Experience building scalable, maintainable, and secure software Rapid iterations using AI-assisted development while maintaining high code quality Clear communication, pragmatic technical decisions, and long-term maintainability If you're looking for a senior engineer who can combine modern full-stack development with production AI to build software that users rely on, I'd be happy to discuss your project. Let's talk about your requirements, architecture, and roadmap.
