Senior Full-Stack Engineer | AI-Powered SaaS & Modern Web Architecture

I’m a senior full-stack engineer with 25+ years of experience building scalable SaaS platforms, AI-powered web applications, and high-performance frontend systems using React, Next.js, TypeScript, and Node.js. I help startups and enterprise teams design and ship production-grade applications that combine modern frontend architecture with clean backend APIs, AWS cloud infrastructure, and AI/LLM integrations (OpenAI-powered workflows, intelligent automation, structured AI outputs). My background includes engineering leadership at Bamboo Health, where I architected a unified frontend platform that reduced development cycle time by 30%, and large-scale frontend modernization at Nordstrom and Monotype. I don’t just build features - I design systems that scale. 🧠 AI + Modern Stack Expertise I specialize in building AI-ready applications that move beyond demos and actually work in production. 1. AI & LLM Integration - OpenAI API integration - LLM-powered SaaS features - Structured output parsing & prompt engineering - AI workflow orchestration - Retrieval-ready architecture (RAG-friendly systems) - AI chat interfaces & intelligent automation tools 2. Full-Stack Development - React, Next.js, TypeScript, JavaScript (ES6+), AngularJS - Node.js, Python backend services & REST APIs, C#, Java, PHP - Authentication & secure role-based systems - SaaS product architecture - Component libraries & design systems - Performance optimization 3. Cloud & DevOps - AWS cloud-native systems - CI/CD pipelines - Vite, Webpack, modern build tooling - Test-driven development (Vitest, Jest, RTL) - Scalable deployment strategies 🏗 What I Build ✔ AI-powered SaaS platforms ✔ Enterprise-grade internal tools ✔ Healthcare & regulated-industry systems ✔ High-performance dashboards ✔ Startup MVPs built to scale ✔ Modernized legacy platforms 💡 How I Work - Architecture-first thinking - Clean, maintainable codebases - Strong API contracts - Clear technical communication - Cross-functional collaboration with product & design - Focus on long-term scalability (not short-term hacks) If you're building a serious product - especially one integrating AI - I can help you architect it correctly from the start and ship it with confidence.
