Judit Sánchez

Full-stack developer with a focus on product: backend, frontend, and infrastructure, not just UI. I've worked on significant projects for companies in various sectors, such as healthcare, eCommerce, and education.

I adapt well to teams: if a stack, design system, or established conventions are already in place, I work within them without imposing my own. If nothing is set up and someone is needed to define the architecture from scratch—backend included—I can do that too, with years of experience deciding what fits best in each case, not out of caprice.

In backend, I work with NestJS, PostgreSQL, and Prisma, building APIs, payment integrations (Stripe), and custom modules as needed for each project. In frontend, mostly ReactJS and Next.js, with Tailwind as a base for custom component libraries. I manage state and requests depending on the project: usually Zustand and React Query. I test with Jest or Vitest for unit tests and Playwright for end-to-end.

I also work with generative AI in real product applications: image, voice, and video generation SDKs, agent frameworks, and models running on the client side. It's not a one-off or a trendy add-on — I integrate it as a normal part of the stack when the product requires it.

I love challenges, I can't sit still, and I enjoy both contributing and learning from those around me.
