Introducing Hemanshu Upadhyay

Builds agents that keep working after he closes the laptop.

Hemanshu is an AI product manager at SimbaStack, where he shipped Ranger, the guest concierge that answers lodge guests over WhatsApp and Telegram, and the 250+ RPS backend under it. He also runs a launchd heartbeat that wakes three agents every fifteen minutes to review diffs, propose docs patches inside a throwaway git worktree, and drive a real browser through his apps hunting bugs; the cheap version of that QA agent found eight cosmetic bugs and missed the one that mattered, the version with memory found the flow that froze the app. He'd enjoy meeting people who run agents unattended in production and have scars to show for it.
