What I'm looking for

I'm looking to build frontend and mobile products where I can simplify complex transaction, authentication, state-management, and integration flows.

I'm a Frontend Engineer with nearly 5 years of experience building and improving web and mobile products using React, Next.js, TypeScript, and React Native. I specialize in frontend architecture, system migrations, SDK integrations, and standardizing complex product flows.

I've led a custom React SSR-to-Next.js migration, integrated multiple authentication and wallet SDKs into a unified mobile finance experience, and improved development and release workflows through reusable architecture and automation.

I enjoy solving complex product and platform problems rather than simply implementing features. I'm especially interested in global, remote-friendly teams where I can work on products at scale, collaborate with strong engineers, and continue growing into a broader Software Engineer role.
