What is the Scouq Library?
The Scouq Library is a growing collection of long-form technical content built around real decisions — infrastructure choices, AI integration patterns, cold email mechanics, and the build-vs-buy tradeoffs that come up in every serious software project.
This is not a blog. Blog posts go stale. Library entries get updated when the underlying facts change. Every claim here is either sourced or marked as an opinion. That distinction matters.
Who writes here?
Right now, just Miles — the founder of Scouq. Scouq is a custom software shop. We build production systems for clients: email engines, admin dashboards, data pipelines, AI agents. The Library documents what we learn along the way.
When something we build works well — or fails in an interesting way — it ends up here.
How the Library is organized
Posts belong to one of four pillars:
- Voice AI — AI phone agents, voice model evaluation, vertical-specific deployments
- Build vs Buy — when to write it yourself, when to buy a SaaS, when to fork something open source
- Cold Email — deliverability, personalization at scale, what actually moves reply rates
- Education — infrastructure, tooling, and everything else that doesn't fit a tighter category
Each post is tagged more specifically within its pillar. You can filter by tag from the main library page.
What you'll find here first
The early entries cover infrastructure decisions we made building Scouq's own email engine — a Rust-based cold email system that runs on a single VPS and handles 35+ active callers. ClickHouse vs TimescaleDB for time-series data. Why we chose Modal for LLM inference over self-hosting. How to structure warmup without triggering spam filters.
Later entries will cover AI voice agents for specific service verticals — HVAC, roofing, property management — based on actual deployment data.
A note on freshness
Each post shows both a published date and an updated date. If those are the same, nothing has changed since it was first written. If updated is more recent, something material changed — the update section at the bottom of the post explains what.
That's the deal. Read what's useful, skip what isn't.
