WORK HISTORY
Senior Lead Engineer @Fidelity Investments
Collaborated in Agile ceremonies, sized user stories accurately, and coordinated deliverables across onsite and offshore teams to ensure timely and high-quality releases.• Modernized a legacy file-processing pipeline by designing a Spring Boot–based File Transformer API using MyBatis, improving bulk data operations and reducing operational overhead.• Engineered high-performance parsers to process GRK and mainframe files, converting large and complex CSV grant datasets into standardized GRK-compliant JSON structures.• Integrated the File Transformer workflow with Azure Blob Storage for secure file ingestion and retrieval, implementing Kerberos authentication to meet enterprise security standards.• Improved overall processing throughput by optimizing transformation logic and reducing latency for high-volume grant, vesting, and distribution records.• Ensured exceptional code quality by achieving 90%+ unit test coverage using JUnit and Mockito, and strengthened CI pipelines using Jenkins for automated builds and testing.• Proactively identified and resolved performance bottlenecks, defects, and stability issues across production workflows, significantly enhancing system reliability.• Documented REST APIs extensively using Swagger and supported knowledge sharing through clear technical documentation for long-term maintainability.
