About

I am a Senior/Staff System Development Engineer (L6) and certified Bar Raiser at Amazon with 20+ years in tech and with 500+ interviews conducted. I am also a seasoned interview coach who has guided 100+ candidates with consistently high reviews, helping engineers land offers across top tech companies. I specialize in Behavioral interviews (up to Staff level) and System Design focused on cloud infrastructure, distributed systems, scalability, and reliability. We can run a realistic, timed mock interview or a conversational strategy session depending on where you are in your prep. During mocks, I take detailed notes and ask the exact probing follow-up questions interviewers use to test your depth and level. Afterward, we go through a clear, honest breakdown of where you stand against your target level's rubric. For behavioral prep, I focus on helping you lead with business impact, use hard data and metrics, highlight complex trade-offs, and show how you build long-term mechanisms. For system design, I focus on requirement scoping, identifying bottlenecks, and defending your architectural choices. You will walk away with detailed notes and a specific action plan on what to refine before interview day.
