Salomão Marques

Professional Profile

I work in the development of web systems, both on the front-end and back-end. I have also worked with mobile and desktop. JavaScript (including jQuery), Python, C# and Java are my main programming languages. I also frequently use other languages for development, such as HTML, CSS (including Bootstrap) and SQL. My main focus in web technology was on .NET Core, but I became more interested in Node.js later. My experience in software desktop was primarily in C# and Java, but they were replaced by Python later.

Visual Studio Code and Android Studio are my favorite IDEs. I use Microsoft SQL Server Management Studio to manage servers, databases, tables, procedures, functions and views.

I also work with Linux, mainly because I also work with Docker, creating and managing images and containers. I also have a online VPS that, along with Nginx I have used in a personal project, contributes to my greater familiarity with the penguin system.

I work collaboratively through Git.

I am a communicative person who works well in a team.

Professional Experience

Systems Analyst at FAST2 Mine - aug/2021 until now.

Currently working on the development of reports and dashboards that are delivered to clients according to their common and specific needs.

HTML, CSS (including Bootstrap), JavaScript (including jQuery), VB.NET (under the .NET Framework), Python and SQL are the languages I have been primarily focusing to.

The main IDEs I use are Visual Studio, Visual Studio Code and Android Studio. I use Microsoft SQL Server Management Studio to manage servers, databases, tables, procedures, functions and views.

I also work with Docker, creating and managing images and containers.

I work collaboratively through Git.

Development Technician at Companhia Siderúrgica Nacional (CSN) - jul/2019 até jul/2021.

I develop web, mobile and desktop systems and maintain existing systems developed internally.

The main programming languages I use are C#, JavaScript (including jQuery) and VB.NET (the latter being mainly for existing systems). I used the Java language for a long time, but currently I left it aside. I like to use C++ for smaller projects that do not require a graphical user interface. As I develop web systems, I also use HTML and CSS (including Bootstrap) languages. The SQL language takes up more than 50% of my work period, as it is present in almost all projects and systems.

The main IDEs I use are Visual Studio, Visual Studio Code and Android Studio. I used NetBeans for a long time when Java was my primary language, but now I have left it aside as well. Microsoft SQL Server is the primary database technology adopted by the company, however I also use SQLite for mobile development. I use Microsoft SQL Server Management Studio to manage servers, databases, tables, procedures, functions and views.

Control Room Technician at Companhia Siderúrgica Nacional (CSN) - sep/2014 até jul/2019.

I manage large-scale mining equipment through radio and an electronic dispatch system that communicates with them in real time.

Complementary Activities

Solo development of a shift schedule application (Shift Scale CMIN) published on the Google Play Store - developed using the Android Studio IDE with the Java e XML languages.
Creating this website that, even though it is simple, led me to develop some skills such as:

Managing Linux VPS (Ubuntu) through SSH (Putty).

Installing, configuring and maintaining Nginx server (including reverse proxy configuration and installation/configuration/maintenance of SSL/TLS certificate - Let's Encrypt - Certbot).

Using the main languages of front-end web development: HTML, CSS (including Bootstrap) and JavaScript (includind jQuery).

Using the C# language with the .NET Core framework - the initial back-end technology of this website.

Using the React library - a front-end technology that I have used on this website.

Using the minimalist framework Express - the current back-end technology of this website - with the template engine EJS (Embedded JavaScript) - the current front-end technology of this website.
