Hi, I’m Raj—CTO and clarity-first systems architect. If your GenAI demo looks great but wobbles in production, your AWS bill stings, or p95 keeps spiking, book a working session. In 60–90 minutes I sit with your team, trace a real user flow, and hand you 3 high-ROI fixes. Within 24 hours, you get a one-page plan with owners, KPIs, and safe rollout steps. Proof I operate at scale: ~4B queries/day, ~75 PB, 99.9% uptime, MTTR ~4h, ~55% infra cost reduction. I’ve led 150+ engineers and shipped products across 5 markets with measurable revenue and CX lift (NPS 78, CSAT 4.1). Pick one focus when you book: RAG in Production (grounding, guardrails, latency) or AWS Cost Kill (20–35% opportunity)—we’ll make the invisible visible and get you to wins you can ship this week.
