What I'm looking for

I’m looking to join a development team where I can contribute from day one and continue growing technically.

At Tarjeta Titanio S.A., I develop and maintain features for the company website and Súper Online, its e-commerce platform, while creating dashboards that help teams identify bottlenecks and make decisions. I also manage data analysis for information about affiliated merchants and have helped add more than 60 merchants to the network.

As a freelance Full Stack Developer, I’ve delivered more than 20 solutions, including real-time systems for basketball clubs, a dental practice management SaaS with WhatsApp appointment booking, and Axon Fire, a mobile emergency management app for firefighters. I also founded GMKITSTUDIO and designed its e-commerce structure and official website.
