I ship production systems, not prototypes. If you need a senior engineer to own your product end-to-end, architecture, AI integration, and delivery, that's what I do. My focus right now is integrating AI into real business operations: agents that handle live operations, RAG pipelines that query real data, and LLM-powered workflows that replace manual processes at scale. What I've shipped recently: → Senior Developer on the engineering team behind an AI voice agent platform that automated 70% of inbound call operations for a US hospitality company. I contributed to the full stack: real-time call handling, RAG pipelines for context retrieval, TTS/STT voice flows, and integrations with PMS and POS systems. Node.js, Python, LangChain — running in production handling real calls daily. → An AI-powered WhatsApp bot for building operations management, handling tenant requests and routing workflows end-to-end. My stack: Node.js, TypeScript, Laravel, Python, Vue/React on the frontend. AWS infrastructure, Docker, CI/CD. I've worked with OpenAI, Anthropic, LangChain, vector databases, and multiple voice AI platforms including VAPI. I work best with founders and technical leaders at US companies who have a real AI problem — not "add AI to our app" but "we need AI to handle 10,000 calls a month" or "we need RAG that actually retrieves the right context." I bring 15 years of production engineering and the ability to own a project from architecture to deployment. If that sounds like what you need, let's talk.
