I've built web and AI-powered applications for Santander Bank, INDITEX, Banco Galicia, and U.S. clients in agriculture and real estate. At Plexus IT, I work across React, TypeScript, Node.js, AWS services, microfrontends, backend APIs, and RAG-based LLM features.
I also built Scanqodex, an event-management SaaS with ticketing, secure QR access, POS and cashless systems, real-time reporting, payments, refunds, permissions, and venue operations. I focus on maintainable, high-performance software that teams can keep evolving, and I enjoy improving developer experience, mentoring junior developers, and solving complex engineering problems.
