I am a Senior Software Engineer with 5 years of experience building highly scalable distributed systems and backend architectures at elite product companies. I have recently been in the trenches, navigating advanced SDE-2 and Senior Backend engineering loops for top-tier tech giants. I know exactly what hiring managers are looking for, where candidates fail in High-Level Design (HLD), and how to survive rigorous DSA rounds. I don't do generic advice. I provide brutal, actionable feedback to help mid-level engineers break into senior roles.
