Igor is a web developer focused on modern PHP and JS, always striving for new technologies. When he wears his back-end hat, he's focused on performant and DRY code, working on API servers or consumers.

Speaker @ PHPeste: RESTful Best Practices

I was invited to speak at PHPeste, the biggest PHP conference from the northern part of Brazil, after a successful CFP submission. My talk was about RESTful do's and dont's, best practices, and tool suggestions to create APIs; I spoke to around 200 people (280 in total at the event).

I was also invited to translate questions for Rasmus Lerdorf, PHP creator.

Geru - Debt Calculator

This was a standalone React project I built. It involved heavy math calculations and featured a series of unit tests to make sure all numbers were crunched correctly, given the company samples.

The original product is now offline, so the link leads to a PR release.

Sameach Vedações - Responsive Redesign

This was an old "product.. display" website that needed a layout revamp. They were advertising online and were receiving a lot of mobile access, so I had to redesign their site with responsiveness in mind.

Konato - Events Directory

An event directory focused on students and professionals alike, searching for talks, congresses and similar activities to boost their curriculum.

Sole developer, building everything from the database to the front- and back-ends, using PHP7, Laravel 5, PostgreSQL, Docker, and Heroku.

It is open-sourced at https://github.com/konato-events/web

Calories - Sample React Project

This was a sample app I created to study and display some React and REST skills. It was based on a friend's ideas, and consists of a small web app to log food calories and control your daily intake - there's also an admin role where someone can alter users. The API explorer is easy to use and enables developers to test the RESTful API methods directly from the documentation page.
