Real-Time Trading Platform
I worked on a real-time crypto and stock trading platform designed to process and display live market data with minimal delay.
The platform receives real-time price and market updates and distributes them to trading components using MQTT and real-time communication services. I worked on APIs and backend services for market data processing, trading signals, order management, portfolio updates, and real-time monitoring.
Key areas of the project included:
Real-time crypto and stock market data
MQTT-based real-time data communication
Live price and market updates
Trading signals and price alerts
Buy/sell order processing
Portfolio and position updates
Market and instrument management
Real-time trading dashboards
High-volume data processing
REST API development
SQL Server database integration
Performance optimization and error handling
Technology: C#, .NET / ASP.NET (http://ASP.NET) Core, Web API, SQL Server, Dapper, MQTT, REST APIs, Azure services.
Key focus: Building reliable real-time backend services capable of processing and distributing live trading data efficiently while keeping the trading platform responsive.

The system supports:
Multiple payment gateway integrations
Deposit and withdrawal processing
Payment authentication and secure API communication
Transaction status verification
Webhooks and callback handling
Payment retry and pending transaction management
Wallet balance updates
Transaction history and tracking
Failed and successful payment handling
Secure payment data processing
Background processing for payment transactions
Database and API integration using .NET and SQL Server
Technology: C#, .NET / ASP.NET (http://ASP.NET) Core, Web API, SQL Server, Dapper, REST APIs, Webhooks, Azure services.
Key focus: Building a reliable and scalable payment architecture that can support multiple payment providers while maintaining accurate transaction and wallet status.
