Fullstack Web Developer — SvelteKit · TypeScript · Cloudflare · Romania
I build real-time, multi-tenant web apps end to end — database schema, API layer, UI, deployment — with SvelteKit 5, TypeScript, Remult, and Cloudflare. I'm finishing a BSc in Accounting & Computer Science (2026) while shipping the production website for Perla Brazilor, a guest house in Bucovina, and building a B2B realtime chat/audio platform.
