Software Development Engineer at Amazon Development Center

November 1, 2024 - Present

Software Development Engineer at Amazon Development Center, Iasi. Led the Claude-powered custom agent for on-call investigations, enabling automatic generation and execution of SQL queries, dataset analysis, and reporting to deliver actionable insights, reducing investigation time and accelerating issue resolution. Refactored the internal bot-detection pipeline to publish results after each model evaluation, lowering latency from 45 minutes to 2–5 minutes per model and improving downstream data consumption. Redesigned the offline detection system's job-processing architecture to support graceful cancellation across EMR steps, SageMaker batch transforms, and Cradle jobs by orchestrating termination of in-flight jobs via Lambda-driven Step Functions logic, reducing operational failures and manual cleanup. Implemented an end-to-end bulk job restart feature for internal jobs, with a REST API and Lambda orchestration, and persisted execution metadata in DynamoDB for real-time backfill pro
