Cover image for 60 days ago, lokerdollar.com (http://lokerdollar.com)
60 days ago, lokerdollar.com (http://lokerdollar.com) had zero visitors. This morning Cloudflare reported 22,840. Then I opened the real analytics. 468. The other ~22k were bots crawling a few thousand job pages. The number I was about to brag about was 98% machines. ─── The honest 60-day growth evaluation. $0 ads. 100% organic. What's working: SEO is doing real work — 20% CTR at position 5.5 for a 2-month-old site. The Bahasa Indonesia job summaries earning their keep, content English aggregators don't bother to write. GEO / agents: people are finding it through ChatGPT. → The build-in-public loop works — Threads sends traffic back. Under the hood: an AI agent does the work a team would — thousands of jobs ingested and auto-summarized in EN + ID, IDR salary conversion, timezone-fit scoring, all autonomous, on a routing layer that keeps cost controlled. What's not (yet): Retention is the frontier. People land, read for ~5 minutes, and don't return. Activation is step one — getting them to take a single action — but the real game is giving them a reason to come back. Same lesson as the bot traffic — I was trusting numbers that didn't tell the truth. The outbound-click event never fired. You can't improve a funnel you can't see, so I built toward the one thing that was lit: traffic. Fixing the measurement first. ─── What I'm sitting with: I spent 60 days proving I can get people to the product. The next 30 are about giving them a reason to stay. Traffic is a vanity metric until someone comes back. hashtag#buildinpublic (https://www.linkedin.com/search/results/all/?keywords=%23buildinpublic&origin=HASH_TAG_FROM_FEED) hashtag#indiehacker (https://www.linkedin.com/search/results/all/?keywords=%23indiehacker&origin=HASH_TAG_FROM_FEED) hashtag#remotework (https://www.linkedin.com/search/results/all/?keywords=%23remotework&origin=HASH_TAG_FROM_FEED) hashtag#startup (https://www.linkedin.com/search/results/all/?keywords=%23startup&origin=HASH_TAG_FROM_FEED) hashtag#saas (https://www.linkedin.com/search/results/all/?keywords=%23saas&origin=HASH_TAG_FROM_FEED)

Cover image for Most LLM telemetry posts brag
Most LLM telemetry posts brag about what they monitor. Here's mine — including what I'm still missing. Built this for lokerdollar.com (http://lokerdollar.com), solo, in production: Covered: — p50 / p95 / p99 latency per task — cost per 1k tokens + daily burn + per-task spend — provider success rates + circuit breaker state — cache hit rate, quota / rate limit tracking — model leaderboard scored on live traffic Gaps I'm still chasing: — prompt versioning tied to quality signals — TTFT for streaming UX (matters for chat tasks) — per-user cost attribution — semantic error taxonomy, not just HTTP codes — push-based degradation alerts (today's playbook is reactive) The lesson from running this solo: observability is never "done." It's a backlog that evolves with the product — and the gap list is more honest signal than the green checkmarks. → Open for AI platform / full-stack work. If you want this layer for your team, my DMs are open.
