    • ABOUT ME

    Jan Pleva

    Frontend Developer with 12+ years of experience delivering digital products for clients across various industries, including e-commerce, insurance, renewable energy, and culture. I craft clean, performant, and maintainable code using modern JavaScript frameworks. My background includes working both in Czechia and the United Kingdom, where I gained valuable experience in fast-paced digital agencies. Over the last three years, I have focused exclusively on SvelteKit and TypeScript as part of a mid-sized development team, building both public-facing websites and robust internal tools.
