Web Developer
Svelte & SvelteKit
I am Jimmy Mostovoi, a passionate developer with more than 3 years of experience using Svelte and SvelteKit. I design fast, modern and tailor-made web solutions — from showcase websites to complex back offices.
Why choose Svelte?
Maximum performance
Svelte compiles your components into optimized vanilla JavaScript at build time — zero runtime, zero overhead. Your pages load instantly.
Modern DX with SvelteKit
SvelteKit brings SSR, static generation, routing and data management into one complete framework, ready for production.
Minimal bundle
Less code sent to the browser, faster loading times and a better Core Web Vitals score — a real SEO advantage.
My services
Design & Architecture
Analysis of your needs and proposal of an optimal technical architecture before writing a single line of code.

Migration and modernization of your existing platforms to the latest versions of Svelte, with zero regression.
