I cut incident investigation time from 2 hours to 2 minutes.
By building an MCP-based AI orchestration platform that coordinates 10+ agents in parallel. That's the kind of problem I live for — finding a 60× improvement where everyone else has accepted the status quo.
This site is 4+ years of notes that started as an ugly Google Doc. That doc got me through Siemens, Walmart, Salesforce, and Microsoft interviews. Last month I thought — why am I keeping this private? So I cleaned it up and put it online. 39,000+ impressions in the first week.
Salesforce — real-time AI routing at enterprise scale
Engineered the sub-100ms agent assignment routing engine across chat, email, and WhatsApp for Omni-Channel. AI-assisted routing signals reduced misrouted interactions by ~30% in early rollouts. Built an MCP-based AI orchestration platform coordinating 10+ specialized agents — cut incident investigation from 2-4 hours to 2 minutes across engineering teams.
Walmart Global Tech — Black Friday-scale distributed systems
Owned a greenfield order management system end-to-end for International Marketplace. Cut delivery time by 25%, shipping costs by 20%. Designed event-driven pipelines that held under peak load serving 400M+ customers. Won the IDC Bravo Award for delivery impact.
Siemens — industrial distributed systems
Re-architected a distributed industrial network product. Improved system availability by 85%, cut API latency by 60%. Built a Neo4j graph-based microservice that reduced network planning time by 70%. Won the Star Performer Award.
Capgemini — where it all started
Fresh grad. ₹3.8 LPA. No IIT. No referrals. Built billing microservices for GE's AMP platform, resolved 95 production bugs. Reduced billing errors by 30%. Not underpaid — underexposed. That's where the foundation was built.
"Bhai, 3 rejections in a row. System design round. I don't know what I'm doing wrong." — 3 sessions later, he DM'd me a screenshot of his Amazon L4 offer letter.
"This is the only site where I actually understood how consistent hashing works in production. Got asked this exact question at my Amazon interview — nailed it."
"Finally someone who explains Spring Security without making my head explode. The filter chain diagram should be in the official docs."
"Use circuit breakers for resilience."
"At Walmart, a missing circuit breaker caused a cascading failure during peak. Here's the exact Resilience4j config that made the difference between 5-minute recovery and a 2-hour outage — and why the default half-open state count was wrong for our traffic pattern."
"ConcurrentHashMap is thread-safe."
"ConcurrentHashMap protects individual get/put. It does NOT make check-then-update atomic. In a mock interview last week, a senior candidate used it for quota checks — both uploads passed and exceeded the limit. You need compareAndSet. Here's why."
100+ engineers mentored 1:1. 90%+ placement rate at Amazon, Google, Salesforce, Microsoft, Walmart, Flipkart. I do System Design mocks, DSA deep-dives, resume reviews, and career strategy sessions.
My approach: I don't teach tricks. In my mock sessions, I play the interviewer who keeps pulling threads — the same way real FAANG interviewers do. If your design has a race condition, I'll find it. If your API leaks private data through search, I'll ask about it. That pressure is what actually prepares you.
