Hi, I’m Aakash Singh, a Software Engineer 2 at Cisco Systems, working on core systems and networking infrastructure powering large-scale production routers. I have hands-on ownership experience in: Linux kernel migration for Cisco Virtual Routers (IOS-XR) Bare-metal & hypervisor environments (ESXi, QEMU, AWS EC2) System bring-up, secure boot, firmware workflows & device drivers Debugging real production issues for global customers (Netflix, Oracle, telecom providers) Low-level C/C++, Linux internals, systemd, containers & crash analysis I’ve also solved 500+ DSA problems and have cracked multiple system-heavy interviews, giving me a strong balance of theory + real-world engineering. What I Can Help You With: 💻 Systems / Infra / Networking Career Mentorship How to break into systems roles (Cisco, Juniper, NVIDIA, Amazon, Google, etc.) Transition from college → product company or service → product Resume reviews focused on systems & infra profiles Choosing the right tech stack (OS, Linux, networking vs web) 🧠 Interview Preparation (Mid-Level / Entry-Level) DSA strategy (what actually matters in interviews) OS, Linux & Networking interview prep C/C++ interview questions & debugging rounds How system design differs for infra roles 🛠 Real-World Engineering Guidance Linux internals & kernel concepts Secure boot, virtualization & containers Bare-metal vs cloud infrastructure How large networking products are built & shipped. 🧑‍🎓 Who Should Book a Session? Students targeting product companies Engineers aiming for systems / infra / networking roles Cisco / networking aspirants Anyone confused between DSA, Dev, Infra, or Systems 🔥 Why Learn From Me? ✅ Currently working on production systems at Cisco ✅ Not just theory — real industry ownership ✅ Clear, honest, no-fluff guidance ✅ Structured plans instead of generic advice 📩 Book a session if you want clarity, direction, and a practical roadmap to crack systems & product-company roles.
