Hi, I'm Jereen 👋
> software engineer · systems & scale
Good backends are invisible. I make them fast too. Mostly Go, Python, and AWS.
I spend my time on the unglamorous problems — distributed systems, event-driven architectures, query latency, the infra nobody sees until it breaks.
Work spans high-throughput Go services on Kafka at multi-petabyte daily scale, a 60% cut in query latency on high-volume analytical workloads, and re-architecting a C++ transaction engine into an actor-based distributed system for a 6x throughput gain.
Mostly write Go and Python, comfortable picking up whatever the problem needs. At home on AWS, GCP, and Kubernetes. Master's in Computer Science from Arizona State University.

Always up for chatting about distributed systems, interesting infra problems, or just saying hi.
