What I'm looking for

I seek frontend roles where I can lead UI performance improvements, collaborate with UX/backend teams, drive testing and CI/CD best practices, and grow technically within an agile, user-focused company.

I am a dedicated Frontend Developer with four years building responsive, user-friendly web applications using modern JavaScript frameworks and technologies.

I have led teams and projects to improve performance and reliability, including reducing load times by 30% through code splitting and lazy loading, and introducing TypeScript to cut runtime errors by 25%.

My work spans React, Next.js, React Native, Tailwind CSS and related tooling, and I emphasize accessibility, testing, and maintainable component-driven architectures.

I collaborate closely with UX and backend teams, evangelize best practices like continuous delivery and testing, and focus on delivering scalable, high-quality user experiences.
