//Full-Stack Web Developer

TEDxUTN Colaborator BarcampBA Speaker and Organizer Hobbyist musician

Hey! I'm Nazareno, a 27 years old web developer from Buenos Aires, Argentina living in Amsterdam. I started programming in my spare time when I was 12 years old in PHP+MySQL+JS and I didn’t stop learning since then.

I worked for all kind of companies, from fintech startups to Facebook; on different positions, from Frontend Developer to Technical Leader of my team. I frequently give talks and seminars about PHP, Web Security, MVC Frameworks and other topics in events and institutes. (PHPDay, EducacionIT, BarCamp, etc.)

Technical Skills

Software Engineering

I care about quality. I like designing solid, reliable and highly scalable systems. I care about choosing the best platform for each project and spending the extra hour to go for the proper solution instead of a quick patch.

Some topics that I love are: Security, Software Architecture, WebServices, Encryption, machine learning.

When I was 20 years old, I was in charge of a PHP course in EducacionIT, one of the biggest IT learning schools in Buenos Aires.


Whatever fits the project. Backend? Most of my experience has been in PHP (including Hack), NodeJS, all kinds of database storages (MySQL, MongoDB, Redis, Prometheus, GraphQL, etc) but I have worked in projects in Python, Java and ASP.NET. Frontend? Javascript (React, flow, ES7, Coffescript, vanilla JS, jQuery and etc), SCSS, templating systems.

Other skills
