Building high-impact
systems at scale.

I build the infrastructure behind conversational AI at Wayfair โ€” routing LLM inputs, processing 400k Kafka messages daily, and automating what used to take engineers 20 minutes by hand. Before that, I shipped microservices at BlackBerry and Kubernetes automation at Wellframe. Northeastern CS, class of 2024.

Where I've built things

Software Engineer

Wayfair November 2024 โ€” Present
  • 01 Designed an LLM-as-a-judge input classification layer for a production chatbot, reducing incorrect escalations by ~23% with real-time alerting for high-risk inputs.
  • 02 Architected a Kafka-based agent status tracking system processing 400k+ messages/day using Avro schemas, Spring Boot JPA, and batch processing.
  • 03 Built a Composer Airflow data pipeline with dbt and Python for metadata aggregation โ€” deduplication, continuous updates, executes in under one minute.

Software Developer Intern

BlackBerry September โ€” December 2023
  • 01 Implemented high-performance API bulk operations using Spring JPA and S3, improving query processing time for two high-priority products.
  • 02 Integrated audit logging across a new Java microservice with Kafka pipelines to the legacy audit system.

DevOps Engineer Co-Op

Wellframe January โ€” July 2022
  • 01 Leveraged Kubernetes to automate database operations, reducing create/delete times by 95% and enabling concurrent SQL instance operations.
  • 02 Built automated environment data population replacing a manual Postgres backup/restore process โ€” 40 minutes down to 10.
