What I'm looking for

I'm looking for mid to senior frontend engineering roles where I can work on meaningful, user-facing products. I enjoy working close to the metal — performance optimization, state management, and scalable architecture are areas I gravitate toward. I value teams with strong engineering culture, clear ownership, and a product they're genuinely proud of.

I'm a Senior Frontend Engineer with 5 years of experience building scalable, high-performance web applications. I currently work at Vinsol | STADIUM, where I've shipped features across products like SnackMagic, SwagMagic, and bystadium.com.

My work spans performance optimization, state management, and developer tooling — some things I'm proud of include cutting build times by ~60% through a Turborepo monorepo migration, improving site performance by 30% with service workers, and building ISR-powered CMS pages for content flexibility without redeployment.

I primarily work with Next.js, React, TypeScript, Redux Toolkit, Apollo GraphQL, and React Query, and have hands-on experience integrating analytics and third-party tools like Mixpanel, Google Tag Manager, HubSpot, and Prismic.io.

Outside of work, I enjoy writing technical deep-dives on web engineering, JavaScript internals, and computer science fundamentals on my blog at dutta-roy-samrat.github.io.
