Shipped the full OSS reliability stack — seven repos, every CI green. Anvil v0.1.0 on npm with SLSA build provenance; Tripwire ships an OpenAI-compatible guard proxy; Goldset's eval Action posts a delta-vs-base PR comment and blocks merges on regression.

  • anvil v0.1.0 — webhook→BullMQ pipeline on npm with SLSA provenance; examples/stripe + examples/github
  • tripwire — OpenAI-compatible sidecar proxy that aborts mid-stream on a rule trip
  • goldset — real LLM-judge eval Action + delta-vs-base PR-comment bot
  • quickdraw v1.0.2 — streaming benchmark CLI (TTFT, p50/p95/p99, cost)
  • codecraft — Vite + editable Monaco + interactive terminal in the browser tab
  • stackup — kind GitOps lab with a real Prometheus success-rate canary
  • a unifying trust-policy SDK that wires Anchor (refuse) + Tripwire (abort) + Goldset (eval-gate) into one declarative policy
  • a cited benchmark of agent-reliability failure modes
  • backend / AI-infra roles at Mumbai or Bangalore startups
  • YC seed founding-engineer roles
  • contract work on RAG, streaming LLM, queue/webhook reliability

Homesty.ai

Live commission-driven AI real-estate advisor.

Production AI advisor on Next.js 16 + pgvector + GPT-4o + Claude. Solo-built. Refusal-first retrieval and mid-stream guardrails were extracted from this work into Anchor and Tripwire — same engine, both public.

Anchor

Provenance-first RAG that refuses to hallucinate.

Cosine-floor retrieval returns chunks when similarity is high, refuses when it isn't. Postgres + pgvector + Next.js. Live playground available.

Codecraft AI

In-browser AI IDE. WebContainer-backed live coding playground.

Boots a real Vite + React dev server in the browser tab via WebContainers. Editable Monaco is wired to the WebContainer filesystem with debounced writes and sub-2s hot-reload; an xterm terminal runs real shell commands; an IndexedDB snapshot cache drops repeat-visit boot under 20s. COOP/COEP cross-origin isolation is what makes SharedArrayBuffer and the in-tab runtime work.

~/tripwire◆ NPM

Tripwire

Mid-stream LLM safety. Catch the lie before the user finishes reading it.

Pattern engine watches LLM streams token-by-token, aborts on rule trip. Sub-millisecond decision latency. Ships an OpenAI-compatible sidecar proxy (POST /v1/chat/completions) that streams responses through the guard and aborts mid-stream on a trip.

~4.7 µs per chunk · zero happy-path buffering

~/goldset◆ NPM

Goldset

Golden datasets + LLM-as-judge + structural assertions, as a GitHub Action.

Three eval runners (golden dataset, LLM-as-judge with a pluggable OpenAI/Anthropic provider, structural assertions), packaged as a GitHub Action that runs on every PR, posts a delta-vs-base comment, and blocks the merge on regression.

1k structural eval cases in ~3 ms

~/quickdraw◆ NPM

Quickdraw

Benchmark LLM streaming. TTFT, TPS, $/1K tokens.

CLI runs prompt sets against models, captures TTFT + tokens/sec, diffs against baseline. Nightly bench wired.
