Ramses Lee

I am a Senior Full Stack Engineer with over 9 years of experience building high-performance, AI-native web applications and interactive user interfaces across distributed systems. My expertise lies in designing and scaling complex, state-heavy UI systems, creative tooling, and integrating LLM-powered workflows, real-time data pipelines, and intelligent automation into production-grade applications. I have a strong track record of owning end-to-end product development, from frontend architecture and UX performance to backend systems and AI infrastructure, ensuring the delivery of fast, scalable, and intuitive interfaces in dynamic environments. I have successfully architected AI-powered commerce intelligence systems, building entire products from scratch using React, TypeScript, and Next.js, while optimizing cloud infrastructure on AWS for improved reliability and scalability. My work includes delivering production-grade AI systems by integrating LLMs, retrieval pipelines, and model-serving infrastructure, improving response accuracy and reducing hallucinations. I've also engineered distributed commerce systems using Java, Node.js, and Kubernetes, developed AI copilots, intelligent automation services, and led service modernization and CI/CD automation efforts. Additionally, I've developed scalable backend services for data-intensive and NLP-oriented workflows, notably reducing latency by 45% through system optimizations.
