I remove the repetitive work
Retyping orders, adding up totals by hand, copying data from a chat into a notebook. That is time you pay for every single day, and a system does it on its own.
I take work off small businesses' hands
The work you do by hand today, a system can do for you.
I build sites and systems that take the orders, do the maths and keep everything in one place. No notebooks, no copying data from one chat to another.
7 systems built for businesses in Colombia, Venezuela and the United States.

One single source of truth
Orders, customers and deliveries stop living across chats, paper and memory. They end up in one place you can actually look up and measure.
Built around how you already work
I don't bend your operation to fit a template. First I learn the process that already works, then I automate it as it is — nobody has to change their habits.

How I work
You know what to expect at every stage
Four steps, each ending in something you can open or read.
- Discovery
I go through how your operation runs today and where the time is going. You get a proposal with fixed scope and price, at no cost.
Proposal with fixed scope and price - Development
I build in short increments and show you progress at a link you can open. Correcting something halfway costs far less than at the end.
A working link from week one - Delivery
I publish the system on your domain, with HTTPS and backups. I walk you through it and leave written instructions for whatever changes often.
Published system and a usage guide - Warranty
If something didn't turn out the way we agreed, I fix it and you pay nothing. You get 30 days and three rounds of adjustments to ask me for whatever you spot. And if something new comes to mind later, just write to me and I'll tell you what it costs before I start.
30 days and 3 rounds of adjustments

FAQ
What people ask before deciding
How long does it take?
It depends on the scope. A catalog with WhatsApp ordering is usually a matter of days; an admin dashboard or a full system, weeks. The delivery date goes in writing in the proposal, before we start.
How much does it cost?
There's no flat rate because no two businesses are alike. The discovery call is free: in 20 minutes I understand what you do by hand and send you a proposal with a fixed scope and price. You pay after approving the demo, not up front.
What if something breaks after delivery?
You get a 30-day warranty and three rounds of adjustments included. If something isn't the way we agreed, I fix it at no cost.
Who owns the system?
You do. It's built with standard tools any other developer can pick up, and if you'd rather host it on your own account I hand it over ready for that. You're not locked in to me.
What happens after delivery?
The system doesn't need me to run. If you'd rather I maintain it, handle changes and answer when something comes up, we agree on a monthly plan sized to what you need.
Do you work with businesses outside Colombia?
Yes. Systems of mine are running in Venezuela and in the United States. Everything is remote, over WhatsApp and video calls, billed in pesos or in dollars.
Is my business too small for this?
No. Every case in this portfolio is a business of one or a few people: an arepa kitchen, a piñata workshop, a barbershop. The system is sized to whatever you do by hand today.
In their words
Who I have worked with
It's so much easier for my customers to place their order now: everything arrives organized straight to my WhatsApp. I can also handle my accounting and inventory from the same panel. It's everything I asked for and more.
With the panel I keep the accounting for the deliveries, and it automatically splits what I owe each courier. It took a lot of work off my plate.
I can upload my products and adjust prices whenever something goes up, plus mark items as sold out, available, or made to order. And on top of that, I keep my accounts from the same site. Excellent work.
Hender CotizSoftware developer · ColombiaBehind every business there is a person doing by hand what a system could be doing. My job is to give those hours back.
I work on my own: whoever takes your first call is the same person who writes the code and the same one who answers when something breaks.
Which part of your operation is still done by hand?
Tell me how your team works today and I'll tell you what can be automated, how long it would take and what it costs. If I can't see a way to help, I'll say so on the same call.
