About the developer
Marcelo Abreu has been developing software for 40 years. After decades building large-scale corporate systems, automation, AI agents and operational tools, he is now turning personal day-to-day problems into polished apps for people who live similar situations.
Marcelo spent his career designing systems that needed to scale, stay secure, adapt to different business rules and keep working when operations depended on them. That background shapes the way these apps are made: simple on the surface, deliberate underneath.
The apps start as solutions to problems Marcelo experiences himself. He tests them in his own routine, looks for the moments where the interface slows him down, then keeps refining until the product feels natural.
The work does not stop at solving one person’s problem. Marcelo studies UX, shares early versions with friends, listens for friction, and turns that feedback into clearer flows, better defaults and more respectful product behavior.
Alongside large business systems, Marcelo has built hundreds of applications, AI robots and automation tools to make operations easier. That history matters: each app here is small enough to feel focused and serious enough to deserve robust engineering.
This site is built as a long-term home for the apps: English by default, Portuguese and Spanish today, and ready for more languages and more categories later.
