I am 15 years experienced C# developer. For the last 9 years, I have been developing solutions for the financial and capital markets and cryptocurrency 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 reports.   - Experience with cloud-based technologies such as AWS / Azure - Clean code adopter. You will always get the most 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 trades 2 assets and has 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 was 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 many 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.
