Top SchoolJunior Garcia is a founder and hands-on engineering leader with eight years of experience building performant web and mobile products, currently leading HeroUI (YC S24) from Buenos Aires. He combines full-stack expertise—React, React Native, Next.js, Node.js, Laravel and Kotlin—with product sensibility, having optimized app performance and developer workflows through mono-repos, TypeScript, and advanced React patterns. At Seeconds and Conexa he delivered measurable wins (50% faster live-reload, 30% memory reduction, offline queues, and a tablet payment app used by thousands), showing strength in both consumer-facing features and enterprise integrations. As a UI and design-systems enthusiast, he contributes to open-source projects like HeroUI and tailwind-variants, improving component APIs, docs, and TypeScript types to boost DX. He’s passionate about JAMstack, developer experience, and mentoring engineers, and often shares learnings via blogging and OSS contributions. Non-obvious: he pairs low-level performance tuning with product-facing design system work, bridging infrastructure optimizations and polished UIs.
