Haroldo Teruya is a Frontend Software Engineer with a decade of experience building high-scale web and hybrid mobile applications, currently shaping frontend architecture at Genna. He began his career in native Android/iOS development and now specializes in bridging native layers with JavaScript via React Native and NativeScript, contributing meaningful open-source packages like the Yoonit component suite. Comfortable across React, Next.js, Redux Toolkit, Zustand and SSR/CSR router strategies, he focuses on performance through code-splitting, lazy loading and pragmatic state design. As a former frontend tech lead, he has defined reusable component systems and led teams to deliver a finance insights platform and robust web PWAs. He’s driven to sharpen product vision and UI/UX craft, pairing technical depth with experience in low-level native integrations (ML and sensors) that many frontend engineers don’t have. Native Portuguese speaker based in Paraná, Brazil, he’s an active community contributor with a public GitHub portfolio.
