I am an experienced C# developer with five years of software development experience. Proficient
in a wide range of technologies including ASP.NET MVC, WPF, WinForms, ADO.NET, Entity
Framework, LINQ, Microsoft SQL Server, HTML, CSS and Bootstrap, I am skilled in both web and
desktop applications.
I use a three-tiered architectural approach to web application development, ensuring scalability,
maintainability, and reliability for each project. This architectural paradigm allows for a clear
separation of concerns, enabling me to deliver high-quality, structured solutions.
In addition to technical skills, I have a strong ability in user interaction and interface design,
improving the overall user experience. Quick learning and adapting to new technologies
combined with a deep understanding of Agile development principles further characterize my
approach to software development.
In the last several years, I have been actively involved in projects related to Payments and Finance
Operations. This includes integration of fiat payment systems (e.g., PayPal, banking APIs),
automated profit/loss accounting, and transaction validation systems. Additionally, I have hands-
on experience working with cryptocurrency transactions (wallets, on-chain/off-chain transfers),
monitoring crypto wallet balances, building internal tools for transaction reconciliation, and
generating detailed financial reports for operations teams.
I have also built custom trading bots and tools using MetaTrader 4/5 and FIX protocol, where I
was responsible for the backend logic of trade execution, fund management, and capital
protection. My work required continuous monitoring of market and user balances, ensuring
reliable and secure operations across multiple financial endpoints.
