👨🏻‍💻 I am a Frontend Developer at Kryptonum, specializing in high-performance web applications. I craft blazing-fast websites using Astro.js, TypeScript, and Sanity.io.

🚀 My obsession with performance means I implement zero-JS by default with strategic hydration - because slow websites are simply unacceptable!

⚡ I believe in building websites that don't just look good, but perform brilliantly. My approach combines static generation with strategic hydration, ensuring optimal user experience across all devices and connections.

🎯 Performance metrics are my north star. I implement automated WebP conversion, responsive images with proper sizes, and intelligent lazy loading to ensure every site I build loads lightning-fast.

♿ Accessibility isn't an afterthought - it's a core principle. I ensure WCAG 2.0 compliance in every project, making the web accessible for everyone.
