Lakshyaraj Singh Rao

I build backend systems that fail safely: webhooks that never run twice, retrieval that admits when it has nothing, streams that stop themselves.

Building Homesty.ai since November 2025. Mumbai, open to Bangalore.

Homesty.ai

A buyer asks about a property and gets answers from the real listing.

Buyers ask listing agents the same five questions about every flat, and agents answer them by hand all day. I have been building Homesty since November 2025 to take that first conversation: the landing page, the chat, a REST API, admin pages, login and an audit log, on Next.js, Node, Postgres and Prisma.

Anvil

Webhooks that run once, even when the provider sends them twice.

Stripe and GitHub re-deliver webhooks, and a worker that crashes after doing the work gets the same event again, so you charge a card twice. Anvil verifies the signature over the raw body, dedupes in Redis on a hash of signature plus payload, and hands the job to a BullMQ worker with a fixed retry schedule and a dead-letter queue.

Anchor

Retrieval that says no source instead of guessing.

Most RAG demos improvise when nothing in the index matches, and in real estate an improvised answer is a legal problem. Anchor runs a cosine search on pgvector and returns a null answer when the best hit falls under a floor you set per index.

Tripwire

Stops an LLM response mid-stream the moment a rule matches.

Checking after the whole response is generated is too late; the user has already read it. Tripwire tests every streamed chunk and aborts the stream on a match. Ships as an OpenAI-compatible proxy.

  • TypeScript
  • Node.js
  • Express
Code (0 stars)npm

Stackup

A production-shaped Kubernetes cluster on a laptop, in one command.

Canary rollouts, metrics and GitOps only make sense together. Stackup bootstraps a kind cluster, ArgoCD syncs the rest, Argo Rollouts canaries advance only while the success rate holds and roll back on their own.

Goldset

A GitHub Action that blocks a merge when an AI app's answers get worse.

Goldset scores the current output against a golden dataset with a judge model and posts the delta on the PR.

  • TypeScript
  • GitHub Actions
Code (0 stars)npm

Quickdraw

Measures how an LLM streams on your network and your prompts.

Records time to first token, tokens per second, latency and cost for your prompts, in CI so the numbers become a trend.

  • TypeScript
  • Node.js
  • GitHub Actions
Code (0 stars)npm

Codecraft

An IDE in the browser that boots a real dev server inside the tab.

Binds Monaco and xterm to a WebContainers Node runtime, so a Vite project runs in the page and edits hot-reload in seconds.

Commits

644 in the last 52 weeks, across 14 repositories

Counts commits to my own repositories. It measures what I write here, not what I land upstream.

Versions, downloads, checks, stars, forks and commits are read from npm and GitHub when the page builds (last at 2026-11-09 15:45 UTC) and refreshed at most once an hour.
