Business automation
Copying one file into another, re-typing the same details, producing the same documents every week: all of it can run on its own. Often with a small tool, delivered in days.

Custom software and automation that fits.
I build small tools, web apps and mobile apps that remove repetitive work and adapt to the way you already work — instead of forcing you to change it.
A concrete example
Four hours of typing, replaced by one click.
A company was preparing its maintenance rounds by hand. The data already existed in a Google Sheet, but someone had to copy it across into their business software, row by row. I built a browser extension that finds the right row and fills the form instead. A person reviews and confirms — that is all that is left to do.

What I build
Three ways to give you your time back.
The common thread: start from what you already do, and remove what slows you down. I am not selling a technology — I am fixing a specific problem.
01 02 Custom software and web apps
For when the spreadsheet runs out of road: case tracking, scheduling, orders, client portals, back-office. A tool shaped around your business, not the other way round.
See business tools03 Mobile apps
For teams working in the field: forms, job tracking, photos, signatures, and syncing back to the office. Android and iOS.
See mobile apps04 Connecting your tools
Your management software, your files, your online shop: I make them talk to each other so the same information is never entered twice.
See how I connect your tools05 Taking over an existing tool
A tool someone else built, no longer maintained or getting fragile? I can take it over, repair it and keep it moving.
Working with me
You talk directly to the person who builds it.
No sales rep, no project manager, no middleman. The person who listens to your problem is the person who writes the code.
I start from how you work today
Before writing anything, I look at how you do it now. The tool should fit your habits, not force you to change them.
I start small where I can
Plenty of problems are solved by a small tool delivered in a few days. You do not need a big project to remove a repetitive task.
You own everything
The code, the accounts and the data are yours. Your tool must not depend on me to keep running.
I stay reachable after delivery
Tools live: there are fixes, adjustments, additions. I do not disappear once the project ships.
The useful question is not “which technology?”. It is: what are you still doing by hand?
Work
Tools already in daily use.
Every project starts from something concrete: data entry that takes too long, a spreadsheet that can no longer keep up, a field team without the right tool.

- 02
I scope it
Scope, timeline and budget written down before anything starts.
- 03
I build
You watch the tool take shape and can try it before it is finished.

Setup, a walkthrough with your team, and the first adjustments.

It evolves
Fixes and new features as real needs come up.
Common questions
What people ask most often.
I am not sure my problem can be automated.
That is the most common starting point, and it is fair enough — it is not your job to know. Just describe what you redo by hand on a regular basis. I will tell you quickly whether it can be automated, and if it cannot, I will say that too.
What does a project cost?
It depends on scope, but for an order of magnitude: a targeted automation starts around €800, and a first version of a business application around €5,000. Anything larger gets a quote after scoping. You get a firm figure after our first conversation, before committing to anything.
How long does it take?
A small automation is often delivered within days. A business or mobile application takes several weeks, depending on how many features it needs and how it connects to your existing tools.
Do I have to change the tools I already use?
Usually not. I would rather plug a tool into what you already use — your spreadsheet, your management software, your files — than ask you to replace everything.
Do you only work in Réunion?
I am available for work in Réunion, on site or remotely. I also work with companies in mainland France and abroad: most projects run perfectly well remotely.
Who owns the code once it is delivered?
You do. The code, the technical accounts and the data belong to you. You can hand it to someone else later if you want to.
Let’s talk
Tell me what you are still doing by hand.
No specification document needed. Tell me what you do, what takes up your time, and what you would rather stop redoing. I reply personally, usually within 24 hours.
