My name is Amir Shakeri , Senior Systems Software Engineer with 7+ years of experience developing production-grade software in C++, Linux, and FreeBSD.
amir@localhost:~ $ uname -a
I develop production-grade software across firewall appliances, embedded platforms, networking systems, and cloud infrastructure, with a focus on performance, reliability, and maintainable design.
I’m comfortable working across the stack,from kernel-level debugging and embedded Linux builds to backend services and production infrastructure.
