Hands-on support
Are you a mid-level engineer who's been stuck at the same level for 2–3 years? Or trying to break into Google, Meta, or another top company but not sure what's actually holding you back?
I've been exactly where you are. Today I work as a Senior SRE at Google, where I own the reliability of Google Search and Gemini AI — systems serving billions of users. Before Google, I spent nearly 7 years at Adobe as an SRE, building and running enterprise-scale infrastructure from the ground up.
Here's what I've learned after 12 years in this industry: most mid-level engineers don't fail because they lack technical skill. They fail because nobody has given them an honest, specific picture of their actual gaps — and a clear plan to close them.
That's what I do.
I can help you with:
→ Cracking FAANG SRE and system design interviews — I know what Google interviewers actually look for
→ Transitioning from a dev or DevOps role into Site Reliability Engineering
→ Getting promoted to Senior or Staff engineer with a concrete roadmap
→ Resume and positioning — how to tell your story for the role you want, not the role you have
My approach:
I don't do generic advice. In our first session, I'll ask hard questions about your specific situation, identify the real blockers, and give you a prioritised plan. Between sessions, I'm available async — you won't be waiting a week to get a question answered.
Background: Senior SRE @ Google (Search & Gemini AI) · Ex-SRE @ Adobe (6+ years) · MBA from IIM Lucknow · M.Tech from BITS Pilani · Author of published work on auto-remediation and SRE practices · 12 years in SRE, DevOps, and infrastructure at scale.

Every trial is a little different–here's what Arun Kumar says about their trial:
In our first call (usually 30 min), we'll cover:
→ Where you are now and where you want to be
→ Your biggest blockers — technical, career, or both
→ Whether my mentorship style is the right fit for you
I'll give you at least one concrete, actionable insight you can use immediately — regardless of whether we continue.
No sales pitch. No generic advice. Just an honest conversation.
