Rockstar🎓
Top SchoolEric Seppanen is an Open Source Rust developer based in California with eight years of professional experience and a long background in storage, firmware, and high-performance systems. He transitioned from decades of C/C++ and kernel work at companies like Pure Storage and Micron to building reliable, memory-safe backend infrastructure in Rust, earning a reputation as a "refugee from memory corruption bugs." Eric has contributed to high-profile projects such as Neon (serverless Postgres) where he improved error propagation, logging, and replication, and to rust-lang’s This Week in Rust tooling, adding link inspection and CI integration. He blends hands-on DevOps and backend engineering, focusing on robustness in distributed systems and control planes. Notably comfortable across firmware, NVMe, kernel-space, and cloud-native serverless architectures, he brings systems-level rigor to open-source projects and production services.
