About Me

I’m a Senior Frontend Developer focused on building scalable, production-grade applications with React, Next.js, and TypeScript, with a strong emphasis on clean architecture and maintainable code.

I have hands-on experience designing frontend architectures from the ground up, including monorepos, modular systems, reusable component libraries, and scalable application structures for large-scale products.

I care deeply about frontend performance and reliability, from optimizing bundle size and API usage to building real-time interfaces capable of handling thousands of concurrent data points.

Beyond writing code, I contribute to technical direction, engineering standards, developer experience, and team-level decisions, helping frontend teams build more consistent and maintainable systems.

I’m continuously expanding my software engineering skills beyond the frontend, with a strong interest in system design, backend engineering, distributed systems, and modern development practices.
