I’m Hildor Junior, a Senior Frontend Engineer based in Porto Alegre, Brazil, with 9+ years delivering high-perf web and mobile apps using React, Next.js, Angular, and Ionic. I design scalable frontend architectures, ship robust UI, and consistently optimize Core Web Vitals to 90+ Lighthouse performance scores, while keeping 99.9% crash-free sessions in production. I thrive in cross-functional teams, guiding frontend best practices, mentoring juniors, and partnering with product managers and designers to ship customer-focused solutions. Over the years I’ve built hybrid mobile apps with Ionic/Angular and React Native, implemented GraphQL APIs for real-time features, and crafted CI/CD pipelines with GitHub Actions. I enjoy bridging frontend and product goals across finance, healthcare, HVAC, construction, and home care sectors, always aiming for high velocity, maintainable code, and a great user experience.…I’m Hildor Junior, a Senior Frontend Engineer based in Porto Alegre, Brazil, with 9+ years delivering high-perf web and mobile apps using React, Next.js, Angular, and Ionic.
