Custom software, the way it should have always been
I build
Whatever you need: from a landing page to a full system.
You launch
Live on the web or Google Play, with support.
Since 2022 I've built real software for real businesses. I founded KILO —a business management system with an app on Google Play— and the agency ZonaJujuy. You work directly with me, no middlemen, and I use Claude and Codex to ship in weeks what used to take months.
Why me
Better than an agency. Faster than a team.
One accountable person, end to end. Senior quality, startup speed.
Fixed price
You know the cost before we start.
Fast delivery
Progress every week, with a live demo.
Senior quality
Architecture built to scale.
All in one place
Design, code, servers and release.
You own the code
Code, credentials and docs are yours.
Real support
After launch, I'm still here.

Frequently asked questions
How much does my project cost?
It depends on scope. You'll find starting prices above; after a 15-minute call I send a fixed, written quote within 48 hours.
How long does it take?
A landing page, about a week. A website, 1–2 weeks. A custom app or system, 4–12 weeks depending on complexity.
How do we get started?
Book a call, tell me the idea and I send a proposal with scope, timeline and price. If it works for you, we sign, you pay the deposit and I start that same week.
Who does the work?
I do, end to end. On large projects I bring in my trusted team from ZonaJujuy, but you always talk to me.
What kind of projects do you take?
Android and iOS apps, business systems, SaaS, MVPs, online stores, WordPress sites, landing pages, WhatsApp bots, AI automations and payment/invoicing integrations.
Do you work with WordPress?
Yes. I build fast, easy-to-manage WordPress sites, and fix or improve the ones you already have.
Can you fix a system or website I already have?
Yes. I review the code, tell you what's wrong and what it costs to fix. I also migrate legacy systems to modern stacks.
Do you publish apps on Google Play and the App Store?
Yes. I handle everything: developer account, listings, screenshots, policies and release. KILO is already on Google Play.
How does the monthly plan work?
You pay a fixed monthly fee and send requests: new features, fixes, screens or websites. I work on one at a time and deliver every few days. Pause or cancel anytime.
How do payments work?
For fixed projects, a deposit and the rest in milestones as I deliver. I accept international payments.
What if I don't like something?
You see a live demo every week and give feedback. We adjust along the way until it is right, within the agreed scope.
Do I own the code?
Yes. At the end you get the source code, credentials and documentation. You're never locked in.
Do you work with international clients?
Yes. I work 100% remotely with clients in Argentina, Latin America, the US and Europe, in English or Spanish.
Do you use AI to code?
Yes, I use Claude and Codex every day. It lets me ship much faster; I review every line before it reaches production.
What happens after launch?
I stay with you for support and maintenance: fixing bugs, adding improvements and monitoring that everything runs.
