I'm a Senior AI Cloud Full Stack Engineer with two decades of hands-on experience building AI-powered systems, cloud infrastructure, and production web applications. My core stack spans LLM workflows, RAG pipelines, and LangChain on the AI side, AWS, Docker, and Kubernetes on the infrastructure side, and React, TypeScript, Go, and Python on the application side, with additional depth in Node.js, PHP, and Java. Twenty years in production systems has taught me one non-negotiable rule: what I deliver has to work, on time, every time. Clients don't have to manage me; I manage the outcome. This may be my first project on Freelancer, but I'm here to connect and collaborate with talented developers, work closely with clients to bring their ideas and projects to life exactly as they envision, and grow a strong freelance career one project at a time. Feel free to reach out anytime to share your ideas or discuss a project.
A senior AI engineer with real production experience. Demonstrated strong expertise in RAG architecture, table-aware chunking, and accurate page-level citations. Delivered a production-grade chatbot with streaming responses and monitoring faster than expected. Proactively identified risks before they became issues and communicated technical decisions clearly. Rare combination of deep technical skills and strong collaboration. I would hire again without hesitation.
