What I'm looking for

I’m looking for challenging projects where I can contribute across architecture, backend development, frontend development, and user experience, prioritizing maintainable code, scalable solutions, and a product-oriented perspective.

At COBER Medicina Privada, I develop custom applications from frontend through backend integration and deployment. I also build SEO-focused landing pages and modernize legacy applications with React and Next.js.

I designed an AI agent using the OpenAI API and set up automations with n8n to handle lead support, qualification, and routing, reducing manual work for the commercial team.

Previously, as an Analista funcional at Gobierno de la Ciudad de Buenos Aires, I coordinated between development teams and end users, defined requirements, and tested and documented applications. I’m looking for challenging projects where I can contribute across architecture, backend, frontend, and user experience, with a focus on maintainable code, scalable solutions, and product thinking.
