Paramvir Singh Karwal
{ backend engineer who makes AI agents deliver }
A software engineer grounded in Java, AWS and large-scale backend systems — now carrying that craft into AI: orchestrating agents, designing the loops that drive them, and shipping working software alongside them.
about
I'm Paramvir Singh Karwal — Param to most people. A software engineer, Computer Science by training, based in Bengaluru.
Eleven years in, my career has spanned telecom, global software products, talent assessment, and financial technology — mostly backend systems that have to stay correct and quick while a great deal of data moves through them. Java and AWS are home ground. I've never cared much for the framework of the month; I care whether the thing behaves at three in the morning.
Day to day
Designing system interactions — pipelines, queues, the scaffolding that keeps large platforms honest. Increasingly that runs through AI, and the centre of gravity has shifted with it: less writing every line myself, more orchestrating the agents that do — and making sure they don't fall over when it matters.
Off the clock
I travel when I can, keep music on in the background, and judge a day partly by its tea. The unhurried hours are where most of my ideas actually arrive.
engineering with ai
Agentic Engineering
Getting AI agents to do real, reliable work — not demos.
AI-augmented development
Weaving GenAI tools — Claude Code, Codex, Copilot — into the daily rhythm of development, review, design and architecture, at team scale.
Multi-agent orchestration
Architecting systems that dispatch many single-purpose agents over a shared queue — partitioned so they never contend.
Agentic loops
Closed-loop autonomy — fix → verify → commit → re-verify — carried to completion, not a single prompt.
Agent reliability
The quiet discipline that makes agents production-grade: liveness watchdogs, crash-safe claim-and-commit, and guards against stale work.
AI-driven delivery
Entire systems shipped in partnership with AI — this very site, and the command-line pipeline behind it, among them.
An AI agent built this entire site — end to end. The old server-backed version was retired, and the static incarnation you’re reading was designed, rebuilt and deployed autonomously by a Claude agent: the craft above, applied to itself.
