Santiago, Chile — Custom development

Custom software
That stands on its own.

Software, websites, apps, and AI solutions for businesses that need custom work—not just a template with a logo swap.

The problem

Most SME websites in Chile are just the same template with a different color.

They load slowly, can’t be edited without extra fees, don’t show up on Google, and no one knows who maintains them. Automating a poorly designed process only makes the problem happen faster.

Mario Ovalle

One person responsible from the first conversation through to operation.

When something breaks in the middle of the night, the phone that rings is mine.

Átomo Studio isn’t a layered agency. I’m the one who diagnoses, designs the experience, writes the code, and gets the system running. When you hire me, you know exactly who’s accountable: the same person from the first conversation to daily operation.

I’m Chilean and French. Fourteen years ago, I came to Chile to reconnect with my roots and meet family I hadn’t known. I worked as a French teacher and later at the airport, surrounded by passengers and teams who had to adapt daily to confusing systems.

That’s where it all started. Seeing so many people waste time because they didn’t understand the system pushed me to find a solution for passengers: first information, then sketches, and finally software. I’ve been building products for a year, but I arrived here with years of experience observing how people work, communicate, and deal with poorly designed processes.

That’s why I don’t start by asking what technology you want. I start by understanding where people get stuck. And there’s one difference that matters more than any tech stack: I don’t just deliver software. I operate it. Every day.

Delivering isn’t the same as operating

Most studios hand over a ZIP file and disappear. The problem shows up three months later when no one knows where the server lives.

A developer who only delivers makes decisions they’ll never pay for. They pick the easiest architecture to code, not the cheapest to maintain. They leave certificates expired, databases unbacked, logs unrotated—because by the time it all blows up, they’ve been paid and are gone.

I make those same decisions knowing I’ll be the one supporting them. That’s the difference between a vendor and a technical partner, and you see it in year two, not week one.

What I have running right now

This isn’t a portfolio of screenshots. It’s live infrastructure that I set up, monitor, and fix. If I can operate mine, I can operate yours.

How I work

Short cycles, a demo every week, and decisions documented where you can read them too. No management layers between you and the coder, because there’s no one else in the middle.

The stack

{{ s }}

What I don’t do

I prefer to say it before the first meeting. If you’re looking for any of this, there are studios that do it better and cheaper than me.

I don’t work with WordPress or builders

Neither for new projects nor to rescue existing ones. It’s a technical choice, not a bias.

I don’t quote without diagnosis

A price given over the phone is a guess. First I understand the problem, then I put the number in writing.

I don’t subcontract the core of the project

I write the architecture and code that support your business. It’s the only way I can be accountable for them later.

Own products

I build and maintain my own tools to handle operations usually left out of a website: coordinating projects, managing content, connecting channels, and knowing what’s happening.

Geo App

Control panel for projects, agents, memory, tasks, and automations. Turns scattered information into decisions and traceable work.

Sitio Control

Android app, backend, and web panel to manage products, inventory, and field operations without relying on loose spreadsheets.

Hermes

Agent bridge for WhatsApp and Telegram, with memory, business rules, and operational alerts. Lets you chat with a system without losing context.

You talk to me, not a sales rep.

Tell me what’s holding your company back. If I can fix it, I’ll tell you how and how much. If I can’t, I’ll tell you who can.

Thank you. We’ll respond within 24 business hours.
