PROFILE

Worked on the intellistream/SAGE repository to deliver foundational platform capabilities, focusing on scalable data processing and workflow execution. Developed the SAGE Core Engine with Directed Acyclic Graph (DAG) management and integrated Ray-based distributed execution, enabling both streaming and one-shot workflows. Enhanced the platform with a Retrieval-Augmented Generation (RAG) powered QA pipeline, incorporating configuration loading, graph construction, and integration of components such as FileSource, QAPromptor, and OpenAIGenerator. Addressed a critical MessageQueue retrieval integrity bug to ensure accurate item tracking and buffer consistency. Utilized Python and YAML, emphasizing backend development, distributed systems, code refactoring, and robust logging for observability.
