Senior Software Engineer building production frontend systems for cybersecurity and data-heavy enterprise products.

I specialize in frontend architecture, design systems, and component libraries — the kind of work that makes large React codebases scalable as teams grow. My core stack is TypeScript, React, Next.js, GraphQL, and MUI.

Always open to interesting technical challenges. Feel free to reach out, view my resume, or explore my portfolio.
