What I'm looking for

I’m looking for a product-minded team where I can own end-to-end features (secure auth, pixel-perfect UI, high test coverage) and build LLM/AI capabilities with a security mindset.

I’m a fullstack, front-heavy developer with 6+ years shipping production web applications across the Next.js, React, and Node.js stack. I’m comfortable owning features end-to-end—from authentication and APIs through pixel-perfect UI—and I recently focused on integrating LLMs into real products.

As a Frontend Lead Frontend Engineer, I led the frontend team delivering a server-side rendered Next.js + TypeScript platform, owning architecture decisions and aligning the HTML / CSS / SCSS testing roadmap with business goals. I mentor mid and junior developers through code reviews and pair programming, partnering with Node.js backend engineers, QA, and product to ship features with high test coverage and minimal regression.

I’m especially strong in building secure, reliable user journeys. I’ve owned authentication architecture (NextAuth and Stytch), including role-based access control, custom middleware, route protection, and session validation—while also maintaining design systems with custom MUI components that translate Figma into pixel-perfect, accessible UI.

In parallel, I’ve delivered AI-forward production experiences, including LLM-integrated chat and admin apps using Next.js, React, and modern UI tooling. I’ve also modernized legacy JavaScript apps onto the MERN stack, added robust Node.js / Express APIs and Storybook consistency, and used integration/unit tests to keep quality high.
