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.

You're building a tech company but you're not technical. You've maybe been burned by a dev shop that over-promised and under-delivered. Your developers give you estimates you can't evaluate. You started building the product but things aren't moving as they should. You need someone in your corner who speaks both business and technology fluently. 𝗪𝗵𝗮𝘁 𝗜 𝗗𝗼 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 𝗦𝘁𝗿𝗮𝘁𝗲𝗴𝘆 Roadmaps, architecture decisions, build vs. buy. I've made these calls dozens of times across different industries. You get pattern recognition, not guesswork. 𝗛𝗶𝗿𝗶𝗻𝗴 & 𝗧𝗲𝗮𝗺 𝗕𝘂𝗶𝗹𝗱𝗶𝗻𝗴 Your first engineering hires will define your culture and velocity for years. I help you build the right team, hand-picked through my agency for your exact business needs, not a generic team that doesn't cater to you. 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝘃𝗶𝘁𝘆 Shipping feels slow, and you don't know why. I diagnose the real bottleneck, then use AI-led development workflows to deliver results faster and uphold product quality through automated QA processes. 𝗗𝘂𝗲 𝗗𝗶𝗹𝗶𝗴𝗲𝗻𝗰𝗲 𝗣𝗿𝗲𝗽𝗮𝗿𝗮𝘁𝗶𝗼𝗻 I've been on both sides of technical due diligence. I know what investors and acquirers look for, and I'll help you tell your technology story credibly and confidently. 𝗩𝗲𝗻𝗱𝗼𝗿 & 𝗔𝗴𝗲𝗻𝗰𝘆 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁 Working with an outsourced team or dev shop? I'll make sure you're not being taken advantage of. I speak their language and I know the games. 𝗕𝗼𝗮𝗿𝗱 & 𝗜𝗻𝘃𝗲𝘀𝘁𝗼𝗿 𝗖𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗶𝗼𝗻 Translating technology into business language. Making the case for technical investment in a way that grows your revenue and saves you money. 𝗪𝗵𝘆 𝗠𝗲 Most fractional CTOs come from one world, either deep technical or pure management. I've done both. I've built and scaled engineering teams from scratch. I've sat in due diligence rooms on both sides of the table. I've worked with non-technical founders who were burned before and needed someone they could actually trust. I don't bill hours to look busy. I'm focused on one thing: making sure your technology is an asset that generates revenue. If you're a founder who needs a senior technical partner without the full-time commitment, let's talk.
