About
I'm a backend engineer who obsesses over system performance, reliability, and scale.
Currently finishing my Masters in Software Engineering at the University of Maryland while building transit data infrastructure at the Center for Advanced Transportation Lab.
Previously at Velotio and Gainsight, I've:
- →Architected event-driven systems handling 100,000+ events/sec with sub-ms latency
- →Built notification infrastructure serving millions of users
- →Developed RAG-based analytics pipelines processing terabytes of data
I'm drawn to hard problems in distributed systems, real-time processing, and ML infrastructure—and I'm looking for teams pushing the boundaries of what's possible at scale.
Here are a few technologies I’ve been working with recently:
- ▹Java
- ▹Spring Boot
- ▹Kafka
- ▹AWS
- ▹Docker
- ▹Microservices
- ▹PostgreSQL
- ▹Redis
