Hi, I’m Goran Cincur, a Front-End Performance Engineer focused on Astro and building fast, accessible web apps with zero unnecessary bloat. With a decade of experience as a software developer, I’ve built accessible, high-performance web applications from the ground up and modernized legacy systems for Fortune 500 clients, improving Core Web Vitals, WCAG compliance, and front-end architecture. For the past two years I’ve lived at the intersection of performance and AI, obsessing over load times, Lighthouse scores, and lean front-ends. I’ve fully integrated AI into my workflow—prompt engineering across Claude, Gemini, and OpenAI—and I’ve built with Claude Code, even shipping open-source AI tools like AICO (AI Citation Content Optimizer) to improve content indexing and AI citations. I test, refine, and ship features with AI-driven development cycles.
