Low Latency Application Development

• Developed ultra-low latency and HFT applications in C++.
• Reduced order book building latency from 500μs to 17μs through optimization techniques, including multithreading, cache padding, branchless programming, and efficient algorithms.
• Wrote CMake scripts for dependency management and build automation.
• Implemented asynchronous and multithreading programming for performance improvements.
• Designed and implemented REST APIs, gRPC, and WebSocket connections in C++.
• Documented C++ software modules using Doxygen for clear and detailed internal documentation.
• Wrote unit tests in C++ using Google Test to ensure code reliability and maintainability.
• Designed a unified architecture in C++ that consolidated multiple applications into a single system with an API interface, reducing development time by 50%.
• Built a Qt-based desktop frontend to provide a graphical user interface for monitoring and controlling the C++ backend, enabling real-time visualization of trading data and system metrics.
• Designed and implemented OAuth-based authentication mechanisms to securely integrate third-party APIs and ensure user authorization workflows.
• Utilized socket programming for communication over TCP, SCTP, and UDP (multicast and broadcast).
• Collaborated on performance measurements and testing in a local lab environment.
• Integrated algorithmic trading strategies with market data for clients.

• Developed RESTful APIs using Python (Django REST Framework).
• Designed and managed databases with PostgreSQL and MongoDB.
• Built gRPC systems and WebSocket connections in Python for real-time communication.
• Worked on AWS cloud technologies such as ECS, EC2, Lambda, KMS, and S3.
• Wrote unit and integration tests using pytest, ensuring comprehensive test coverage.
• Created test-cases from live financial data using Python libraries, numpy and pandas.
• Integrated Stripe payment gateway for both one-time and recurring payments.
• Documented APIs using Swagger and OpenAPI specifications for easy developer integration.
• Deployed multi-container applications using Docker Compose.
• Managed microservices deployment and scaling with Kubernetes.
