What I'm looking for

I'm looking for a remote or hybrid position with a competitive salary, opportunities to grow, and a modern tech stack.

At Critical Software, I develop React and Next.js applications for ITER CODAC, the control and data platform supporting ITER fusion operations. My work includes applications for pulse schedule preparation and data visualisation tools.

I’ve improved performance in large-scale data workflows, maintained shared UI libraries, and helped the team adopt AI-assisted development practices. I also take part in frontend discussions with clients.

At NielsenIQ, I built, documented, and deployed a JavaScript utility library that centralized survey logic and provided reusable functions loaded via CDN. I also refined survey interfaces and automated deployment tasks in an Agile environment.

Earlier, I worked on large-scale editorial websites at E-borealis, building and maintaining UI components while optimizing performance and SEO. Before moving into software development, I researched and managed historical documents at Biblioteca Nacional de la República Argentina, including work on collections for a journalistic photographic archive.
