Custom tools
A small app made for one job in your business, so nobody does it by hand again.
Like: a budgeting app built around how one artist gets paid.
Custom tools for small businesses
You repeat a task every week. I build the tool that does it for you.
I am Olivier. I turn slow, repetitive work into small tools made for one job: yours. Built with AI, directed and tested by me.
- 9 case studiesEach one started as a real problem, mine or a friend's.
- Try before you ask6 of them have a demo you can run right in your browser.
- Remote, from CanadaGMT-5. Part-time and on call. Pricing on request.

What I can take off your plate
If you can describe the task, I can probably build a tool for it. Here is the kind of work I do.
Safer routines
Risky steps get a preview, a backup and a clear confirmation before anything changes.
Like: a console that writes checked database scripts in place of hand-typed commands.
Alerts and automation
Rules that watch for what matters and tell you, so you stop checking.
Like: office lights that flash when an important notification arrives.
Planners and calculators
Turn a messy calculation into a clear plan you can follow step by step.
Like: a planner that lays out a build and tracks progress as you go.
Selected projects
Tools built for real problems
Every project page explains the problem, what the tool does, and what it changed.
Studio Ledger
A private budgeting app built around how an artist gets paid for commissions.
Safe SQL console
Writes database scripts with a preview, a backup and a dry run, so a typo cannot cause permanent damage.
Light alerts
Rules that turn notifications into light signals, so you stop checking your phone.
Logic designer
Describe a circuit in plain English. It designs it, checks it and shows how to build it.
Before and after
What changed, with no invented numbers
Where I have no number, I say what changed and leave the number out.
Tracking an artist's income
- Before
- A notes app.
- After
- One place for commissions, bills and budget. Used every other day.
Banning an account safely
- Before
- Typed by hand. Several minutes each, and one typo could damage the database.
- After
- A checked script with a preview and a backup.
Noticing what matters
- Before
- An old app that had stopped working.
- After
- Office lights that signal the right notifications, many times a day.
How I work
Small steps, so you see it early
A short call
You show me the task and where the time goes.
A small first version
Something you can click, fast.
Your feedback
We fix what feels wrong in real use.
Delivery
The tool, how to run it, and the files. It is yours.
Support
I stay reachable when something changes.
How I work with AI
Built with AI. Directed and tested by a person.
I say this plainly because you should know how your tool is made.
- The ideas and the decisions are mine, or yours.
- The AI writes most of the code. That is why it is fast.
- I try every tool myself before I trust it.
- Demos and tests use invented data, never real records.
What takes too much of your week?
Describe it in a few lines. I will reply with what a tool could do, and whether it is worth building.
