Evaluation lab
The RAG palette on this site is only worth trusting if its evaluation is inspectable. This page publishes the whole thing: the questions, the scoring rules, every result, the retrieval numbers, the adversarial cases, and how each run compared with the last. It is regenerated by npm run evals; nothing on it is typed by hand.
- Retrieval
- cloudflare:@cf/baai/bge-m3@1024, cosine similarity over the site's chunks, top 8, threshold 0.42. Calibrated on 15 Sep 2026 for bge-m3: on-topic questions score at or above 0.44, off-topic ones at or below 0.37 (on gemini-embedding-2 the same gap sat at 0.65 and 0.55, threshold 0.60).
- Generation
- groq/openai/gpt-oss-120b, gemini-3.5-flash-lite with a JSON response, temperature 0.2, prompt version p4. The prompt allows only the numbered sources, requires a citation on every factual sentence, and returns NOT_ON_SITE when nothing applies.
- Cost
- Free tiers only: Cloudflare Workers AI for embeddings (10,000 neurons a day; the whole index costs about 250), Groq for generation (30 requests a minute, low reasoning effort), Gemini as the fallback. Per answer, the mean is 1167 prompt and 99 output tokens. The eval runner caches query embeddings so a re-run spends nothing on retrieval.
- Not claimed
- The "similarity" figure shown under an answer is the mean cosine score of the chunks used. It is not a calibrated probability of correctness and is not reported as one.
Grounding
At least one citation points at an expected source, and every citation is an expected source or a general one about him (profile, changelog, testimonials, and the writing, which is derived from the case studies). Retrieval is scored separately: was an expected source in the top 8 above threshold (recall@8), and how high (MRR).
passHas he handled payment webhooks in production?rank 1 · 608 ms

passWhat is Notify?rank 1 · 1115 ms
Notify is a multi-tenant notification service built in Java 21 and Spring Boot 3.5 that processes one event into separate delivery jobs for each matched channel, using PostgreSQL as the source of truth and RabbitMQ as the broker [1][4]. It supports in-app, email (via Resend) and push (Firebase, VAPID) delivery, with a scheduled worker that batches jobs every five seconds and retries failures up to three times [1][3]. The service has been in production since May 2026, handling over 1,300 jobs with a delivery success rate of 98.1% [5][7].

Notify has delivered 1,321 notification jobs.
passWhat happens in Notify if RabbitMQ is down when an event is published?rank 1 · 981 ms
If RabbitMQ is down, the event is still written to Postgres with status QUEUED and committed, so the row remains in the database. A recovery sweep runs periodically (every 60 seconds) and republishes any queued events that have been waiting, ensuring the message is eventually sent when the broker is available again.

passHow did he stop wrong facts reaching production on the Margo Rubber site?rank 1 · 1049 ms
He introduced build-time correctness checks that cause the build to fail whenever content is wrong, showing the field path of the error, and he routed all factual values through a facts registry where unknown entries are set to null and omitted from the page. This, combined with a forbidden-claims list and validation gates for links, claims, schema and forms, ensures that no unverified fact reaches production.[2][4]
