Apps, software and automation for businesses
Less manual work. More time for your business.
I build applications, custom software and websites. I connect your tools and automate workflows to help you organize work and serve your customers.
What does your business need?
A solution for what is slowing you down
If you repeat tasks, work with disconnected tools or have an app idea, we can start there. We define the problem and build a solution with a clear scope.
Automate time-consuming tasks
Connect forms, orders, catalogs and reports to avoid copying the same information between systems. We review your workflow and available integrations before building.
Build an application for your business
I design and develop iPhone apps and custom software, from the user experience to testing and launch preparation.
Make your business easier to find and contact
A clear website to explain your services, show your work and receive inquiries. If you need to sell online, we define the catalog, orders and payments as part of an e-commerce project.
Organize customer inquiries with AI agents
Help answer common questions and organize inquiries using your business information. We agree on channels, boundaries and when a person needs to step in.
Keep your tools working
Technical guidance, maintenance and improvements to keep your website and tools working for your business.

Independent apps and games.

Alongside developing independent products, I work with businesses to improve their digital presence and processes. Here is what some of my clients share about their experience.
"Working with Juan Diego was an incredible experience. He helped us create a modern, functional website that perfectly reflects our painting company. His attention to detail and his ability to understand our needs were exceptional. Thanks to his work, our customers can now find us easily and see our services with a single click."
"The website Juan Diego built completely transformed our online presence. Our customers can now browse our catalog of headlights and tail lights and place orders easily. On top of that, his ongoing technical support gives us peace of mind and the confidence to keep growing. Recommended 100%!"
