    I am an enthusiastic back end .NET developer. I have deep experience with C#, SQL, API's, cloud technologies (AWS and Azure), and much more since 2016. I am fairly new to the UpWork platform, and most recently worked for Moody's Analytics for the past 4 years. I loved my time there, but wanted to pursue some personal projects and a more active lifestyle. In my spare time I enjoy rock climbing and remodeling my house :) One project I am especially proud of is developing an original search algorithm similar to Zillow Zestimate. I greatly improved the accuracy of the results from the old algorithm by using complex mathematical formulas, and reduced the query time from 20+ seconds to a small fraction of a second. Another fun project was running risk analysis calculations for investment portfolios, which required 100k to 2mm service bus messages and calculations per request. To achieve this in real-time, my team and I engineered a microservice structure with Azure Functions that scaled on demand. We were extremely detail oriented with our code and the settings in Azure to make sure everything ran quickly and with minimal cost.

    Hello! As a freelance full stack developer with expertise in various languages including C, C++, Delphi, C#, Java, Python, HTML, CSS, Javascript and SQL, I can assist you in building a wide range of applications and systems based on your needs. If you require a simple CRUD application, I can create a user-friendly interface and implement the necessary functionality to manage your data efficiently. Whether it's a basic application or a more complex one, I have the skills to deliver high-quality results. Building websites is another area of my expertise. I can design and develop websites of any kind, whether it's a personal blog, an e-commerce platform, or a corporate website. I am proficient in HTML, CSS, and JavaScript, allowing me to create responsive and visually appealing websites. If you need to build an API (Application Programming Interface) for your application, I can design and develop RESTful APIs that allow seamless communication between different systems or services. I can ensure that your API is secure, scalable, and well-documented. Complex web automation is also within my skill set. I am experienced in using libraries such as Requests and Beautiful Soup for tasks like data extraction and manipulation. Additionally, if you prefer to use Selenium for web automation, I can work with that as well. Scraping data from websites is another area where I can assist. I can develop scripts or tools to extract specific data points or gather information from multiple sources, providing you with the required data in a structured format. Importing and exporting data is crucial for many projects. Whether you need to migrate data between systems or integrate data from different sources, I can design and implement efficient solutions to ensure smooth data transfer and synchronization. Throughout the development process, I prioritize clean code, maintainability, and performance. I follow industry best practices and utilize version control systems to ensure the reliability and quality of the software I deliver. As a freelance developer, I am self-motivated and committed to delivering high-quality results. I am eager to collaborate with you and build exceptional software solutions that meet your specific needs. Let's work together to bring your vision to life!

    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.

C# Developer Hiring FAQs

What is a C# developer?

C# developers write quality code for responsive desktop and web applications or back-end processes. C# is an adaptable, object-oriented programming (OOP) language based on the Common Language Infrastructure.

How do you hire a C# developer?

You can source C# developer talent on Upwork by following these three steps:

  • Write a project description. You’ll want to determine your scope of work and the skills and requirements you are looking for in a C# developer.
  • Post it on Upwork. Once you’ve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
  • Shortlist and interview C# developer. Once the proposals start coming in, create a shortlist of the professionals you want to interview. 

Of these three steps, your project description is where you will determine your scope of work and the specific type of C# developer you need to complete your project.

How much does it cost to hire a C# developer?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced C# developer may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their C# developer services more competitively. 

Rates typically charged by C# developers on Upwork are:

  • Beginner: $25 per hour
  • Intermediate: $47 per hour
  • Advanced: $120 per hour

Which one is right for you will depend on the specifics of your project. 

How do you write a C# developer job post?

Your job post is your chance to describe your project scope, budget, and talent needs. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.

Job post title

Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample C# developer job post titles:

  • C# developer needed for macroverse engineering support
  • Seeking C# developer for an educational game
  • Looking for a C# developer for a real estate app

Project description

An effective C# developer job post should include: 

  • Scope of work: From configuration to execution, list all the deliverables you’ll need. 
  • Project length: Your job post should indicate whether this is a smaller or larger project. 
  • Background: If you prefer experience with certain industries, software, or architectural patterns, mention this here. 
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

C# developer job responsibilities

Here are some examples of C# developer job responsibilities:

  • Take an application storyboard from concept to reality
  • Outline, write, and maintain functional, responsive, and reliable C# code
  • Plan and build user interfaces and interactive media applications
  • Identify and fix bugs and bottlenecks

C# developer job requirements and qualifications

Be sure to include any requirements and qualifications you’re looking for in a C# developer. Here are some examples:

  • Experience working in various C# ecosystems and using OOP
  • Background in building RESTful web services with WCF/WebAPI
  • Familiar with an array of architectural and design practices
  • History of supporting business processes with clean C# code and database schemas
