Lessons
1RevOps & the GTM funnel, end to end46 min read
RevOps is an operating model, not a tool. The funnel taxonomy that every downstream report inherits, the unit economics that should govern tool choice, why schema-first beats tooling-first, and how GTM engineering sits on top of the RevOps foundation — with the interview questions that probe all of it.

2CRM data modeling & hygiene48 min read
The Salesforce object model vs HubSpot’s shared-database property model, which side hosts the join, dedup that survives scale (normalize → hash → fuzzy → semantic), matching rules and duplicate jobs, and the lifecycle plumbing that breaks most automations — with the schema-design interview drill.

3APIs, webhooks & auth49 min read
OAuth refresh loops for outbound CRM calls, HMAC-signed webhooks with timestamp replay defense for inbound events, idempotency keys that make retries safe, token-bucket throttling against shared rate limits, and exponential backoff with jitter — the integration spine of every GTM stack, with the integrate-two-tools interview drill.

4Enrichment waterfalls in Clay47 min read
The column-as-step model, why a waterfall lifts email coverage from ~60–70% to >90%, pay-per-match credit economics, conditional “run only if” runs that hit tier-2 providers only when tier-1 misses, when each source wins, and Claygent for per-row research — the engine room of a GTM stack, with the build-a-pipeline interview drill.

5Low-code vs custom code46 min read
Where the low-code ceiling actually hits (active-record volume, branching depth, latency SLA, provider count), why low-code and custom code are complements not substitutes, the front-door / second-floor pattern of a custom service behind a low-code UI, and the observability gap that bites — with the build-vs-buy interview drill.

6Capstone: lead enrich → score → CRM → alert pipeline50 min read
Assemble the whole stack: four independent stages with explicit contracts, a waterfall enrichment front, a structured-output scoring step (with the additive-scoring footgun and refusal handling), an idempotent CRM upsert, and a graduated alert ladder — then defend every decision the way the Clay take-home and live walkthrough demand.
