    I am 15 years experienced C# developer. For the last 7 years, I have been developing solutions for the financial and capital markets as well as for the Cryptocurrencies Markets.  Main Skills:  - Strong understanding of MQL5 scripting language (MetaTrader 5 Platform) - Strong experience in algo-trading development in MT5 and in C# - .NET Framework with its newest features - Experience with ASP.NET MVC  - Strong understanding of the structure and logic of Object-Oriented programming - Hands-on experience with REST services / APIs - Efficient with databases like MSSQL and MySQL - Collaborative team member with good communication and everyday workflow report.   - Experience with cloud-based technologies such as AWS / Azure - Clean code adopter. You will always get the more efficient and cleaner code possible. Even though 7 years is not a huge amount of time, I already have done several bots (Stock, Futures, and Forex) for the MT5 Platform as well as some interesting and complex solutions. - Copy trade solution for the Brazilian stock and future markets. This solution made it possible to copy trades executed in an MT5 account to several other MT5 accounts or non-MT5 accounts sending the order through the FIX protocol directly to the Broker system. Besides the usual copy-trade functionality, the solution allowed us to have several "Master Accounts" and the users could choose, in a web-based interface, the Master Account they wanted to "follow".   - Copy trade solution for the Binance, Bittrex, and Kraken Crypto Exchanges. I used the same logic already written in the Solution for the Stock and Futures but have implemented a "Bridge" to execute the orders among these Exchanges mentioned.   - Arbitrage bot (MT5) in the Brazilian futures market. This arbitrage bot trade 2 assets and have an extraordinarily high percentage of winning trades, too bad that we can only explore a little window of time: About 3 hours once a month, so the bot only trades once per month. - Long-Short bot for the CriptoExcnhage Bitmex. This bot is way simpler than the other solutions but was fun to build. The bot sent 2 orders at the same time in two different accounts, the first one is a long order, and the second one was short. After that, it keeps doing a trailing stop seeking to find that great "all of sudden" highs or lows that happen in the crypto world. The whole idea was to be already with a position opened to get the full movement of the asset. Well, these were just a few examples of solutions I have already done, there are much more. I will always seek the best way to solve/build a solution, If you are on the lookout for a hard-working and dedicated person, do connect with me.  Thanks in advance.

    Hi! I'm Pedro, an Argentine-Italian professional based in Brazil since 2018. After seven years of working in the advertising and social media field, I decided to migrate to the technology area. I did a six-month bootcamp where I learned the basics of Front-end and Back-end development, using JavaScript. Following that experience, I decided to specialize in the QA area. I started doing a Testing Manual course and, since then, I've been acquiring knowledge in this field in a self-taught way. Right now, I'm looking for opportunities as a QA Analyst, while contributing to the open-source academy UPEX, a reference in the Spanish-speaking testing community. With them, I gained experience in a real work environment, using tools like Jira and Xray and processes like BDD, with Gherkin. Also, I've just finished a Cypress bootcamp, where I was able to develop a full project for E2E and API testing, using JavaScript, Node.js, Page Object Model, Custom Commands, Cucumber, PostgreSQL, Gherkin, Allure Reports, and clean architecture. Besides that, I'm currently learning automation with Selenium and Python, BDD, SQL, and API Testing (with Postman). Regarding soft skills, I consider myself an organized and meticulous person, and I like being part of projects that aim to deliver quality products and services. I'm interested in sports —football, especially—, politics, history, geography, and education. Also, I developed a project as a volunteer in a school in Salvador, Brazil, where I created a workshop for teenagers focused on social inclusion.
