About

I’m a Senior Frontend Engineer with over 6 years of experience building enterprise web applications using React, Next.js, and TypeScript. Throughout my career, I’ve worked across AI, Insurance, FinTech, HR Technology, Entertainment, and Retail industries, delivering products that balance business goals with long-term maintainability.

Beyond building features, I enjoy improving engineering systems—whether that means optimizing build pipelines, designing reusable component architectures, standardizing coding practices, or mentoring engineers. I believe great frontend engineering is about creating software that scales for both users and development teams.

My current focus includes AI-powered enterprise applications, frontend architecture, technical leadership, and continuous engineering improvement.

I believe great frontend engineering is more than shipping features. it's about building scalable systems, improving developer experience, and enabling teams to deliver software with confidence.
