William Aguera is a Lead Full Stack Engineer with a decade of hands-on experience delivering web applications across fintech, healthcare, eCommerce, and logistics. He currently leads a migration from AngularJS to Next.js, modernizing frontends while maintaining legacy systems and improving performance through responsive React components and tighter backend integrations. Equally comfortable on the backend, he manages Node.js services, third-party integrations (Twilio, Auth0), and AWS-backed CI/CD pipelines to ensure production reliability. William brings a strong accessibility and UX sensibility from earlier roles building medical and enterprise apps, and has a track record of introducing structured state management and automated testing to improve maintainability. He’s pragmatic about both code quality and team workflows, often bridging design, DevOps, and architecture to ship practical solutions. Based in Paraná, Brazil, he pairs Angular deep expertise with modern React/NestJS stacks and a taste for improving developer experience behind the scenes.
