About me

I'm a software engineer who enjoys building systems where performance, correctness, and reliability matter. My experience spans distributed backend services, blockchain infrastructure, cryptographic systems, and low-latency transaction processing.

I've worked on production systems involving Rust, Tokio, Kafka, Redis, gRPC, Kubernetes, and AWS. I enjoy profiling real workloads, debugging difficult concurrency problems, and improving how services behave under load.

Outside my professional work, I contribute to open-source projects across the Rust ecosystem and enjoy exploring systems programming, infrastructure, and performance engineering.
