What I'm looking for

I seek remote-first roles where I can lead front-end architecture, build Svelte-based products, optimize performance, and deliver accessible, maintainable user experiences.

I am a senior software engineer with 5+ years of hands-on experience in Svelte, SvelteKit, and modern front-end technologies. I specialize in rapid prototyping, performance optimization, and building scalable, user-centric applications for SMEs, startups, and enterprise clients while collaborating effectively with distributed, remote-first teams.

I have delivered multiple production-ready products, built reusable UI component libraries, implemented CI/CD pipelines and automated testing, and developed full-stack solutions using Node.js and SQL databases. I am passionate about accessibility, maintainable code, and contributing to high-impact, innovative products that solve real business problems.
