What I'm looking for

I’m looking for a Senior Frontend / Frontend Lead role where I can drive architecture decisions, strengthen design-system quality, and deliver pixel-perfect, high-performance user experiences at scale.

I’m a Senior Frontend Developer with 6 years of experience building scalable, high-performance web applications using React.js, Next.js, TypeScript, and the MERN Stack. Currently, I’m serving as Tech Lead at a B2B fintech company, where I own the full frontend architecture for an Admin Portal and a Storefront platform.

I lead component design systems and clean state management, while driving performance optimization and defining code review standards. I mentor developers, set frontend best practices, and collaborate closely with product and design teams to ship pixel-perfect, production-grade UIs.

Before this, I built and maintained frontend modules for enterprise products, integrating REST APIs for complex HR and identity governance workflows. I’m now seeking a Senior Frontend / Frontend Lead role to drive architecture decisions and deliver impactful user experiences at scale.
