About Yurii Kovalenko
I’m Yurii Kovalenko — 5 years of production experience with WordPress, Vue, Nuxt, and SvelteKit (building custom themes & native Gutenberg blocks) and 4 years leading delivery teams. I regularly ship my own side projects — like a computer-vision squash coach, a clock sounds app, and AI Divi — while leveraging Data Engineering and AI-driven development over the past year.
