About

I'm a Fullstack Developer from Buenos Aires, Argentina, with a passion for building scalable and efficient web applications. I specialize in both frontend and backend development, with a focus on creating solutions that solve real business problems.

Currently, I'm a Developer at MAILAMERICAS , where I work on Enterprise Resource Planning (ERP) systems. I lead development efforts, supervise team members, and drive architectural improvements. I've optimized database performance by 200% through SQL indexing, refactored legacy code to reduce runtime from 2 hours to under 1 minute, and automated key business processes using Python and integration tools.

I'm proficient in modern web technologies including React, Next.js, TypeScript, and Python. I have experience managing cloud infrastructure on Microsoft Azure, working with SQL Server databases, and implementing business process automation. I'm committed to writing clean, maintainable code and sharing knowledge with my team through documentation and mentorship.

Beyond work, you can find me exploring new technologies, contributing to open-source projects, or enjoying the Buenos Aires tech community.
