What I do

Three ways SmithBuilder makes a small business easier to run.

Pick the one that hurts most. Most projects start with a single, useful build, then grow from there.

01
AI, used practically

AI for the busywork

Real AI that does the work, not a chatbot bolted on for show. I build the assistant, agent, or automation behind one specific result, with the option to run it privately so your data stays in-house.

  • Custom AI assistants and agents built around one specific job
  • Browser and app automation for repetitive web work
  • Document and data AI: search, summarize, extract, and route
  • Private, self-hosted models so sensitive data never leaves
  • AI content and media: copy, voiceover, and short video
  • Scheduled digests and reports, generated automatically
  • Human review and guardrails on everything
02
Websites that earn

Websites that sell

A site that turns visitors into customers: clear offer, clean path to contact or checkout, and the launch assets to actually get it seen.

  • Marketing and landing pages that convert
  • Local business and service websites
  • Shopify and ecommerce storefronts
  • Contact, booking, and lead-capture funnels
  • Conversion copy and content structure
  • App store listings, screenshots, and launch videos
  • SEO basics and analytics
03
Tools that fit

Apps, tools & automation

Custom software that replaces the spreadsheet-and-email chaos: lightweight, owned by you, and built to connect the systems you already use.

  • Web apps and customer portals
  • Mobile apps for iOS and Android
  • Internal dashboards and admin tools
  • Chrome extensions and browser tools
  • Calculators, intake, and utility tools
  • Automations that connect the tools you already use

What this looks like

In plain terms, here's the kind of work I take on.

01

Turn a service-business website into a clear sales funnel.

02

Add online booking, intake, payments, or lead qualification.

03

Automate repetitive customer emails and follow-ups.

04

Replace spreadsheet-and-email chaos with one small internal tool.

05

Stand up an AI assistant that drafts, summarizes, and routes work, with a human in control.

06

Clean up a scattered online presence so customers and search understand the business.

How it works

A short path from "this is messy" to "this works."

No bloated transformation project. One leverage point at a time, shipped and measured.

01

Diagnose

Map the goal, the current website and tools, and the workflows you repeat every week.

02

Pick the first build

Choose the one website, funnel, automation, or app that creates value fastest.

03

Build & test

Ship a working version, walk the real user path, and confirm it actually improves the business.

04

Hand off & improve

Train your team, document how it works, and plan the next iteration.

Selected work

A few things I've built and launched.

A curated set, not an archive. Real products, real launches, real ownership.

SusFlag

susflag.com

A Chrome extension that flags zero-feedback sellers and Classified Ads on eBay, so you can hide or dim risky listings before you click. Every decision runs locally in your browser.

Live in the Chrome Web Store. Pay-once, no accounts, no telemetry: all the filtering happens on your machine.

Coming soon

A family app that takes the chaos out of school mornings. Kids check in their wake time and what they want to eat, parents get a live dashboard, and a guided Morning Mode walks the whole house out the door.

Kids check in, parents see everything at a glance, and Morning Mode sequences the rush. Bilingual, and built to lower the stress instead of adding to it.

homefolk.app

A shared to-do and grocery app for the people you live with. Chores, errands, and store lists stay in one place that updates live on every phone, so nobody has to ask who's doing what.

One shared list for the whole house: assignments, recurring chores, and store-specific grocery lists that sync instantly across iPhone, Android, and web.

Private app

A local-first money manager: bank accounts via Plaid, AI that runs on your own machine, and Gmail and Google Calendar tied in.

Local, private, and secure by design. Your financial data never leaves your hardware.

Oliver Smith founded SmithBuilder LLC to do the practical version of this work: web, automation, and AI that ends in a working system, not a plan that sits in a drawer.
