Building useful internet businesses in public
I'm David Miles. I design, build, and operate a small portfolio of production websites and interactive tools — and I write about what's working, what isn't, and what I'm learning along the way.
What I'm building, and why
Most people have one project. I have a portfolio — a growing set of niche, useful sites I run as independent businesses. Here's the thinking behind them.
Utility over fluff
I build interactive tools and calculators people actually search for and use — not brochure sites. Useful beats clever.
Built in public
Every project gets a build log: what I tried, what ranked, what flopped, and the numbers behind it. The setbacks are part of the story.
Independent & operated
These are my own businesses, run for the long term — not client work. The goal is durable, useful sites that compound over time.
The Portfolio
Five live properties, each built and operated independently. Every one has a build log telling the real story behind it.
RemodelCalculators
A 40+ construction calculator suite covering drywall, concrete, paint, roofing, flooring, and more — with Pro tools for contractors.
RightDumpster
The honest guide to renting a dumpster — sizes, costs, permits, and city-specific rules with a weight-aware sizing calculator and no spam calls.
MeetBackdrops
Virtual set design studio offering studio-quality 4K backgrounds for Zoom, Teams, and Google Meet — designed as cohesive sets, not stock photos.
WolfResume
AI-powered resume generator engineered for ATS parsing and recruiter-ready structure — not a template builder, not raw ChatGPT.
PromptDynamo
Done-for-you AI prompt packs built for working professionals. Instant download, Stripe checkout, and zero account friction.
Hi, I'm David Miles
I build and operate niche websites and interactive tools as my own businesses. No clients, no agency — just a portfolio of useful sites I grow over the long term, and an open record of how it's going.
The first stretch of any project is mostly quiet. Then a few pages reach page one, the data starts pointing somewhere, and the work compounds. I document that whole arc here — the experiments, the numbers, and the lessons — so the wins and the dead ends are both on the record.
