I ship production kernel & device-driver code at Qualcomm — and I've spent 181K+ impressions teaching engineers what's actually under the hood. Most engineers can write code. Very few understand what's beneath it — how memory really works, what the kernel is doing, why the systems-design round breaks them. That's my whole world. Book a systems mock, a resume review, or ongoing mentorship. If you've ever felt like everyone else "just gets" the low-level stuff and you're faking it — that's exactly who I help.
