> Bangalore. I build backend systems that fail safely: webhooks that never run
> twice, retrieval that admits when it has nothing, streams that stop
> themselves. Software engineer at Homesty.ai LLP since November 2025, building
> the buyer-facing side of a property site. B.Tech in Computer Science,
> Manipal University Jaipur, graduating 2026.

## Work
- Homesty.ai: a buyer asks about a property and gets answers from the real listing. I build the landing page, the chat, the REST API, admin pages, login and an audit log, on Next.js, Node.js, PostgreSQL and Prisma. https://homesty.ai

## Projects
- Anvil: webhooks that run once, even when the provider sends them twice. Signature check over the raw body, Redis dedupe on a hash of signature plus payload, BullMQ worker with a fixed retry schedule and a dead-letter queue. https://github.com/ykstorm/anvil
- Anchor: retrieval that says no source instead of guessing. Cosine search on pgvector that returns a null answer below a floor set per index. https://github.com/ykstorm/anchor
- Tripwire: stops an LLM response mid-stream the moment a rule matches. Ships as an OpenAI-compatible proxy. https://github.com/ykstorm/tripwire
- Stackup: a production-shaped Kubernetes cluster on a laptop, in one command. kind, ArgoCD, Argo Rollouts canaries gated on the success rate. https://github.com/ykstorm/stackup
- Goldset: a GitHub Action that blocks a merge when an AI app's answers get worse. https://github.com/ykstorm/goldset
- Quickdraw: measures how an LLM streams on your network and your prompts, in CI. https://github.com/ykstorm/quickdraw
- Codecraft: an IDE in the browser that boots a real dev server inside the tab, on WebContainers. https://github.com/ykstorm/codecraft-ai
