• Define scalable, high-performance frontend architectures, taking into account performance requirements and future growth; • Diagnose and resolve complex performance issues, especially those related to the JavaScript runtime and the event loop; • Actively participate in technical discussions, proposing appropriate rendering strategies (CSR, SSR, SSG, ISR) for each project; • Identify and remediate security vulnerabilities in frontend applications (XSS, CSRF, sensitive data leaks); • Lead initiatives to improve application quality, testability, and accessibility; • Implement and optimize build processes to improve performance and security; • Publish technical guidelines to standardize best practices across the team.

• Develop and maintain React web applications with a modular, reusable architecture. • Lead technical decisions regarding architecture, coding standards, and front-end best practices. • Use Claude Code to generate, review, and document code, as well as to create automated tests. • Integrate REST and GraphQL APIs, including data consumption and processing. • Ensure application performance and accessibility (Core Web Vitals, Lighthouse). • Guide and mentor mid-level and junior developers. • Collaborate with backend, UX/UI, and product teams. • Implement unit and integration tests (Jest, React Testing Library). • Create clear, up-to-date technical documentation. • Participate in code reviews, proposing technical and architectural improvements.

• Be one of the primary contributors to @owner/ui, our shared component library used across mobile, web, POS, guest app, and white-label apps, helping make the "right way" the easiest way for product teams across Owner. • Drive the cross-platform UI strategy on the Point of Sale (Quick Service) team, building components once that work everywhere using React Native + React Native Web • Work alongside engineers across the organization to shape component patterns, design primitives, and standards in @owner/ui that scale across teams. • Lead active build-out of UI features and components for the Quick Service POS — this is a high-execution, high-impact phase of the product • Reduce UX drift and maintenance overhead by establishing shared patterns that make onboarding faster and feature development more consistent

• Development and maintenance of medium- and high-complexity features, directly contributing to the product’s scalability and the satisfaction of our end users. • Technical refinement of solutions in collaboration with Product and Design teams, ensuring technical feasibility and visual fidelity (pixel-perfect) from conception in Figma. • Implementation of automated tests and monitoring of production applications, with a focus on innovation, continuous improvement, and ecosystem stability.
