Software Architecture

"What do a 1982 banking system and the app you want to launch in 2026 have in common?"

I don’t chase development trends: I build apps with 'iron-grade engineering', from the foundation —the same discipline I used programming COBOL in 1982, when rigor was law— so your iOS and Android product not only works today, but survives the market, scales with order, and lasts for years.

Frequently Asked Questions

How long does it take to build a professional app?

A robust MVP takes between 4 and 12 weeks. I optimize timelines using reusable native architecture, AI tools, and Live Coding sessions—without sacrificing quality.

Why is native development better for my business?

For high-performance projects, native (Swift/Kotlin) gives full hardware access and reduces the risk of breaking changes in future iOS/Android updates.

Who owns the app’s source code?

You own 100% of the IP. At the end, I deliver source code, graphic assets, and store access so you fully control your technology asset.

What happens if my app suddenly reaches thousands of users?

The engineering is designed to scale using cloud services that grow with demand—maintaining speed and stability.

Do you help people download my app?

Yes. We also offer digital marketing: pre-launch, acquisition, and retention focused on real users.

Do you provide support after publishing to the stores?

Yes. Ongoing maintenance: OS updates, fixes, and new features based on user feedback.

Juan Carlos Pazos Founder & Senior Architect

I’ve been building software since I was 17. I grew with technology: from mainframes to desktop, web development, marketing, and consulting—and today, at 61, I enjoy building apps for iOS and Android.

My commitment is robustness. As the creator of Datafox Point of Sale, I know software is much more than UI: it’s a tool that grows the business and survives the real world.
