Work History

Software Development Engineer II

Amazon
08.2019 - Current
  • Designed and implemented an end-to-end automated ML retraining and deployment pipeline using SageMaker for training, Step Functions for orchestration, and CodeDeploy for rollout. Integrated model monitoring, rollback mechanisms, and version control via CodeCommit, enabling continuous evaluation and safe deployment of models. This system accelerated model update cycles from quarterly to weekly, improving model responsiveness to data drift and operational changes.
  • Built a scalable brand relationship detection pipeline using batch inference in SageMaker, cutting manual data audits by 80%.
  • Partnered with Amazon Robotics to launch a container orchestration platform, now live in multiple U.S. fulfillment centers.
  • Reduced container pickup latency by 97% by implementing a real-time container tracking and orchestration system in collaboration with Amazon Robotics. Led architectural improvements by decoupling orchestration logic into micro-services and introducing an event-driven workflow using SQS and ECS, which boosted Proteus robot utilization by 25% and resulted in an estimated $4.2M in annual operational savings across multiple U.S. fulfillment centers.
  • Led safety initiatives at air hubs, cutting overweight bag incidents by 47% and improving workplace safety.
  • Developed and maintained internal CI/CD pipelines for secure, multi-account AWS deployments with automated testing and rollback.
  • Built and maintained high-throughput, low-latency services for real-time decision-making in operational workflows.
  • Mentored junior engineers and interns in cloud architecture, system design, and best practices.

Software Development Engineer I

Amazon
02.2017 - 07.2019
  • Migrated a 19TB distributed relational database to AWS OpenSearch, ensuring 100% data consistency in reads during the transition and enabling 49M reads and 8.3M writes every 5 minutes.
  • Built scalable fraud detection systems to prevent collusion between buyers and sellers across the platform. Designed a high-throughput data ingestion pipeline using SQS and Kinesis for message streaming, and Kinesis Analytics for real-time processing and anomaly detection. The processed data acts as a primary feature source for fraud detection models, enabling accurate, timely predictions and supporting multiple internal teams in relationship-based fraud detection and prevention efforts.
