Develop backend applications in C# using the .NET framework, including asynchronous batch jobs capable of processing up to million records. Write and validate SQL queries for feature testing and prepare required records for integration testing. Use Docker to orchestrate multi-container test environments (e.g., SQL, Confluent). Support deployment via Azure DevOps Pipelines across multiple domains and environments, monitor CI/CD pipelines, and perform control runs before/around releases. Collaborate with stakeholders to gather and refine requirements and produce functional/technical documentation. Execute testing across environments to ensure reliability and assist with deployment incidents by analyzing issues and providing fixes.
Managed the Automatic Train Supervision Subsystem codebase, using C++ to resolve issues found during testing. Used pipelining to launch applications related to the ATS subsystem. Learned Microsoft Foundation Classes (MFC) and worked with XML documents.
