I'm a Front-End Performance Engineer focused on building fast, accessible, and utility-first web apps with zero unnecessary bloat. With 10 years of experience as a software developer, I’ve delivered high-performance web applications from the ground up and modernized legacy systems for Fortune 500 clients, focusing on Core Web Vitals, WCAG compliance, and scalable front-end architectures. In the last two years I’ve integrated AI deeply into my workflow, using Claude, Gemini, and GPT-4 to design, prompt engineer, and ship lean full-stack features. I also co-created AICO, an AI Citation Content Optimizer, to help clients maintain strong AI-visible content, and built an AI testing agent to validate end-to-end flows.
