Rahman Khan

Building cloud infrastructure for the agentic era.

Products & Solutions at Pico Public Cloud, Dhaka. 24 years of infrastructure experience across enterprise systems, cloud platforms, and network operations.

What I work on

  • Cloud platform products: what enterprises actually ask for versus what vendors sell
  • Cost and operations: Kubernetes economics, multi-tenant attribution, FinOps
  • Security depth: zero trust, application protection, detection engineering

Open source

  • Contributing to CNCF projects (OpenCost, FinOps and cloud-native tooling)
  • failover-budget — measuring real DNS and GSLB recovery time (bdNOG22 talk)

Writing

I publish technical articles on cloud infrastructure thrice a week on LinkedIn. Everything here comes from production work, not vendor decks.

Research

Applied data exploration and network modeling from my FAO years. Google Scholar — 62 citations, avian influenza surveillance networks.

📍 Dhaka, Bangladesh
