Work Experience

Freelance Full-stack Developer

2010 - PRESENT

Self-employed

Developed several comic-style pages for different movies and one car brand. The pages were built with small animations as the user scrolled down and played some sounds. The modern JavaScript framework was not present yet, so it was challenging.
Maintained a clone of a creative portfolio platform targeted at architecture firms. I received the project semi-finished and in bad shape, but I managed to fix and organize the whole application.
Migrated said application to React with Next.js and Laravel after a few years of maintenance. Collaborated with another PHP developer and coordinated work with him, a sysadmin, and a QA tester to build, test, and upload the application.
Built a lot of smaller projects, including eCommerce, WordPress, and landing pages, and a teaching-oriented site.

Full-stack Tech Leader

2006 - PRESENT

Digbang

Developed several apps, including a CRM that integrates all of the banks' systems into one, MercadoLibre competitor in Argentina, food delivery app used by restaurants and customers, and site that creates and stores trusts using blockchain.
Kicked up almost every site in the company and worked on them from six months to a year by creating the main site skeleton and its most complex features. I've started every React project and most of the Laravel projects too.
Onboarded and taught newcomers what they needed to work in the company, from PHP to React, helping them with minor things or big things, teaching them everything they need to know, sometimes working with them for months side by side on projects.
Acted as a project manager when needed. I led some projects as the project manager and main developer, leading small teams of 5-7 people, organizing daily tasks, and communicating with our clients.
Gave in-house lessons and presentations, trying to keep everyone up to date with the latest technologies and other cool new things. From time to time, I create different courses to give within the company, and anyone is free to join.
