I'm a full-stack web & mobile developer with experience in building web & mobile applications. I build fully production level applications of any difficulty, from static one-page websites to multi-page dynamic web applications. I care about clean code and pixel-accurate UI as much as I care about things actually working in production. Available globally, flexible with time-zones, and always happy to talk through a project before committing to anything. You can find more information at - Portfolio Website. Technologies I work with: Frontend: React, Next.js, Svelte, SvelteKit, TypeScript/…
