Speaker @ PHPeste: RESTful Best Practices

https://www.slideshare.net/igorsantos07/restfuuuu-boas-prticas-restful-phpeste-2017
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 dos and don'ts, 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, the PHP creator.

eHungry Manager

https://play.google.com/store/apps/details?id=com.ehungry.manager
A React PWA was built from the bare layout and has been the sole maintainer for many years. The focus is to display order details for kitchen employees and some related functions.

It was later integrated into a Cordova (legacy) shell, so it's distributed as a native application (Android and iOS) as well. It included a PHP-based (Restler) API, tested via Codeception, and got internationalized to other languages.

Clockify Targets

https://clockify-targets.web.app
This was created as a standalone API consumer for the Clockify time-tracking app. The main objective is to help organize my monthly hour budget at work. Soon after, Clockify launched a marketplace for add-ons, and the next step is to integrate my project into it.

It's a SvelteKit project that was deployed to Firebase and is using LocalStorage (for now).

Mini-calc

https://chromewebstore.google.com/detail/minicalc-de-financas-pess/dcjlnkbkpjdgjemfjgnoklibjijfbgmg
A Svelte pet project from my free time, simplifying some routine math tasks for monthly budgeting and investments. It's currently released as a Chrome extension and automatically deployed via GitHub Actions and GitHub Pages.

Konato | Events Directory

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

I was the 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.

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.

Sameach Vedações - responsive redesign

This was an old "products 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.
