Summary
👤
Senior🎓
Top SchoolEric Lagergren is a Senior Mission Software Engineer with 12+ years building secure, reliable, and scalable systems ranging from cloud microservices to satellite flight software. He drives end-to-end engineering—architecture, crypto design, implementation, and long-term maintenance—and has led teams shipping Rust-based decentralized platforms and Go backends for end-to-end encrypted collaboration. At SpiderOak he owned cryptographic and interoperability work (TPMs, SE, TEE) and led certification efforts, and he now applies that mission-focused experience at Anduril. An active open-source contributor, he has improved core Go tooling and libraries (golang/go, golang/sys) and fixed subtle cross-compiler and CI issues in notable C++ and Go projects. He blends low-level systems proficiency (syscalls, memory management, assembly) with practical product integrations—cube-sat deployments, AWS/Azure infrastructure, and transport-agnostic encrypted channels—ensuring security is the default, not an afterthought.

[mirror] Go packages for low-level interaction with the operating system
Role in this project:Back-end Developer
Back-end DeveloperContributions:6 commits in 7 years 10 months
Contributions summary:Eric primarily contributed to the `golang/sys` repository by implementing and modifying system calls, specifically related to file system operations and memory management. They added support for the `posix_fadvise` system call on Linux and FreeBSD, and regenerated constants. Furthermore, the user introduced and removed the MemfdSecret system call for Linux. These changes involved modifications across various architecture-specific syscall files and included optimizations, demonstrating a strong understanding of low-level system interactions within the Go programming language.
