Senior AI & Full-Stack Engineer | LLM Systems & Cloud Architecture

You've probably seen an AI demo that looked brilliant and then fell apart the moment real users touched it. That's the gap I work in. I build LLM-powered features and AI agents that survive production, plus the full-stack SaaS around them, deployed on cloud infrastructure that scales without surprises. Lately that's meant an AI research and analysis platform for a scientific R&D team, an AI office management system handling finance, payroll and document intelligence, and workflow automation for a productivity SaaS. Cloud architecture is where I'm strongest, with deep AWS experience across Lambda, Amplify, DynamoDB, Cognito and AppSync. Tech stack: React, Next.js, Node.js, TypeScript, Python, AWS, OpenAI API, Claude API, LangChain, vector databases (Pinecone, ChromaDB), n8n. 7 years full-stack, 22 jobs delivered, Top Rated. So, what are you building? Send me the details and I'll tell you honestly whether I'm the right fit.
