Experience
Restify Log Middleware
I have meticulously crafted a highly adaptable middleware that has become indispensable in all my projects. Now, with great excitement, I am delighted to share that this remarkable middleware is readily accessible for download on the prestigious npm platform. With a harmonious balance between simplicity and robust functionality, it effortlessly caters to a diverse range of applications, cementing its position as a go-to solution for developers across various domains. Integrating this middleware into your projects allows you to streamline your development process, enhance efficiency, and unlock new possibilities in your software endeavors.
Restify No CAPTCHA
This is a type of small middleware adapted from Express npm middleware to work with Restify using a no CAPTCHA from Google. It allows you to use it before a controller gets called to validate the user with a CAPTCHA response.
Life Care | Cuidados Pela Vida
This project involved a Brazillian mobile outsourced app. I worked as a software consultant (via TuntsCorp) along with Icons4u development. Our team started working on it in November 2016, and we finished at the end of January 2017. It is an Ionic-based app that helps users use their Aché Laboratories relationship program.
App features:
• GPS step monitor.
• Medicine reminder with local notification.
• Drug registration to gain discounts with Aché Laboratories.
• Push notifications to send promotions to users.
I worked with a team of five developers as a senior software engineer.
Main tasks:
• Helped my team to develop our tasks with a good schedule.
• Worked hands-on with Cordova plugins such as geolocalization, background tasks, and local and push notifications.
• Worked hands-on with CSS to make the layout responsive for multiple devices such as iPhone 4 to iPhone 6 plus and tablets.
• Deployed the app both for Android and iOS.

Project Skeleton for an API Using GraphQL and Express.js
https://github.com/makinhs/node-graphql-tutorialThis is a public project that I've made to write an article on the Toptal blog.
It was created using TypeScript, Express.js, and GraphQL. It was meant to be a starting point for new projects and/or for new developers to understand the basic configuration of Express.js with GraphQL configuration using Node.js.

Restify Basic Skeleton
This is a project I've made to speed up my API development. It's organized to have a better coding structure, faster deployment, and production-ready for crafting MVPs and proof of concepts.
Project Skeleton for a REST API
https://github.com/makinhs/rest-api-tutorialThis was a starting point for a REST API project that uses Node.js with Express.js and ECMAScript 6 to speed up the start of API development. It was also used for my article posted on a Toptal blog that provides an explanation on REST architecture and shows how I was working with Express.js and Node.js at the time.
Although the code uses ECMAScript 6 instead of TypeScript, I have other private projects that use TypeScript instead of ECMAScript 6 for Node.js and Express.js.

NestJS with GraphQL and Authentication
https://github.com/makinhs/nestjs-with-graphql/tree/004-mongodb-authAs a writer enthusiast, I like writing personal articles in my spare time.
This project was made to give an introduction to new developers to the NestJS environment. I made a personal guide on some of the critical topics you need to know to play with NestJS, then explained how to work with Mongoose (for MongoDB), GraphQL, unit and e2e testing, authentication, as well as configuring the Github Actions for running automated tests.
