About

A Frontend Engineer focused on building scalable, high-performance web applications with React, Next.js, and TypeScript. I care about clean architecture, predictable state management, and performance that holds up in production, not just visuals. I work with modern frontend patterns, API integration, and optimization techniques to ensure applications stay fast, maintainable, and extensible as they grow. I also contribute to open-source projects, including react-jsonschema-form, a widely used React-based form framework. I value clarity over complexity and make technical decisions based on real trade-offs, not trends. Currently focused on improving frontend scalability, performance, and developer experience.
