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.

Hello! I am a computer engineer working with mobile development, specializing in Android UI development. I worked on mobile projects, such as health, finances, e-commerce, and well-being. With the diversity of the projects I worked in, I implemented several types of screen and UI components, such as: - Sign up and login; - Lists; - Product details; - Search with filters; - Scanners (QR Code and Barcode); - Product checkouts; - Video; - Notifications; - Forms; - and many others. I specialized in UI development because I enjoy studying and thinking about UX, but I'm also comfortable with working with everything in the Android environment. I was part of the development team of the Medite.se app, a meditation app that was awarded the Hidden Gem Award in the Google Play Store, in 2017, as one of the best apps released in that year. My work experience in different companies allowed me to participate in the whole development cycle, from the requirements definitions, through development, testing, deployment to Google Play Store, and maintenance so I can assist you in every step. I have a passion for excellence, and I am always looking to develop pixel-perfect UI. I am constantly studying and practicing to improve my knowledge and skills in pursuit of mastery. I look forward to working with you!

I build digital tools and experiences, often programming the more complex pieces so others can use these tools to build the full web app. Additionally I advise what is possible to be done given a timeline and a budget and continue to share my impressions so we can adjust and manage risks based on how development actually progresses. It is time to kick off that new priority in your company! I work mainly with frontend and application logic, with basic infra skills to get my work online. By application logic I mean generating PDFs, payment processing, maps and vehicle routes, and so on. By frontend I mean what the user of the app sees, including very dynamic app screens. I have thousands of hours of work on these two plugins here, I use them as the flagship examples of my past work of creating plugins for a no code platform, one is a powerful PDF designer and generator that has worked reliably since 2018 and the other is a powerful multi purpose map component, it has a large variety of features to meet a very wide array of use cases, see their links in the portfolio section please. As you can see I produced documentation and provided support as well, until I sold them both in 2024. I also made dozens of other plugins, including Stripe and other integrations, data dump processing (ETL), charts, VoIP and phone calls (Telnyx), browser extensions, automated scraping, SFTP client, code highlighter, words highlighter and a myriad other app logic needs. I also worked with different serverless functions providers, specifically Microsoft Azure functions, Netlify functions and AWS Lambda functions. Now, more recently I built Tupan, which is my current side project, also see its link in the portfolio section. Tupan is a nocode tool to create web apps. I made a write up on Tupan's internals and why I took each decision, you can see the link in the portfolio section too. So alongside general app logic and Bubble plugins, I have experience with: - SvelteKit which handles the frontend with dynamic and static pages; - Appwrite which handles the backend with users, functions, database and more, it is a Supabase alternative; - Docker to maintain the app online. - Caddy to serve as a whitelabel manager and front door of the whole stack. With me, you always get an instruction manual alongside the code. Projects include deployment to live, when applicable.

I've been working with IT since 2009 and during my trajectory I realized that the most important thing between a customer and supplier relationship is trust. In these years of experience, I worked in website development, script development for servers and network administration. I also managed several projects in the technology area and that's why I can keep my work organized. At my college, I learned several programming languages, worked with some databases, but my focus is currently developing applications with Bubble.

Hello, my name is Daniel I live in Brazil and work as a freelancer. I develop apps with Bubble.io because I believe that application development can be fast and easy. Our clients can not wait, so the tools to develop their solutions need to provide an environment where it's possible to quickly implement the ideas and release an MVP. With this concept in mind, I started developing applications using no-code and low-code approaches. For the last two years, I have been working as a web developer at Bubble.io. So I think I have the basic knowledge needed to help you develop your project.
