What I'm looking for

I’m looking for a role where I can build enterprise-grade, accessible, high-performance UIs—partnering with UX and backend teams in Agile. I want ownership of React/front-end architecture and the chance to modernize platforms using Oracle VBS/APEX where relevant.

I’m a Senior Frontend Engineer with 15+ years of experience building enterprise web applications using React.js, JavaScript, HTML5, CSS3, and modern frontend architectures. I focus on responsive, accessible, and high-performance user interfaces, and I enjoy translating product and UX intent into production-ready UI.

Over the past 5+ years, I’ve developed enterprise React.js applications using reusable components, REST APIs, Redux, and modern JavaScript. I’ve also worked hands-on with Next.js App Router concepts, including TypeScript, SSR, and SSG, while strengthening engineering fundamentals like React Hooks and Context API.

Recently, I’ve been building enterprise solutions with Oracle Visual Builder Studio (VBS) and Oracle APEX, integrating REST APIs and third-party services to deliver dynamic business functionality. I consistently optimize performance (e.g., lazy loading, code splitting, memoization) and improve usability through WCAG accessibility standards, cross-browser compatibility, and collaboration across Agile Scrum teams with Product Owners, UX teams, and backend developers.
