I'm a full-stack engineer focused on AI-first applications and RAG systems, delivering frontend-heavy, production-ready solutions in React, Next.js, TypeScript, and Tailwind. I design and implement multi-step reasoning, context management, and prompt architectures to build AI assistants that scale from prototype to production. I collaborate across disciplines, own projects from concept to deployment, and prioritize accessibility, performance, and clean engineering practices while integrating open-source and hosted LLMs through HTTP/SDK APIs.…I'm a full-stack engineer focused on AI-first applications and RAG systems, delivering frontend-heavy, production-ready solutions in React, Next.js, TypeScript, and Tailwind.
