Profile
I am a Senior Software Engineer working on distributed systems for billing, inventory, fulfillment, and security analytics. Across PayPal, Nordstrom, and Securonix, my work has centered on a practical question: how do we keep business state correct when services fail, events arrive twice, or a platform needs to recover?
Experience

PayPal, Inc.

March 2020–December 2024
Nordstrom, Inc.
Senior Software Engineer
- Moving fulfillment decisions beyond distance-only routing, with controlled experiments and operational fallbacks.
- Replacing slow, manual allocation workflows with an explainable engine that planners could control.
- Building a consistent inventory model across store, warehouse, and vendor availability.
- Separating high-volume traffic from critical operations and making failed publishes recoverable.

Securonix, Inc.
Software Engineer
- Scaling security investigation across high-volume indexing and hot, warm, and cold data.
- Solr performance improved approximately twofold through tuning, routing, and implicit sharding. Separately, the multi-cluster indexing design supported rates up to approximately 500,000 events per second. These are distinct performance results.
