Turning complex ideas into working products
Marcelo is a hands-on product builder who enjoys solving problems that seem complex or impossible at first. He treats hard challenges as the interesting part of the work — the place where real products are born.
He learns technologies quickly when they help solve real-world challenges, and focuses on turning ideas into practical software products using AI, automation and modern cloud infrastructure. The goal is always the same: ship systems that businesses actually use every day.
What I build
Software designed around real operational needs — not technology for its own sake.
Intelligent automation systems
Automations that remove repetitive work and connect tools into reliable end-to-end flows.
WhatsApp & workflow automation
Customer service routing, message automations and business process execution over WhatsApp.
Desktop apps with offline capability
Cross-platform desktop software that keeps working without a connection, with sync and backups.
Multi-tenant business systems
Operational systems with isolated data, roles and permissions designed for real companies.
API integrations & dashboards
Connecting external services and surfacing the data that matters in operational dashboards.
Selected product case studies
Real systems shipped for real business workflows.

How I think
Product building is not about choosing trendy tools. It is about understanding the problem deeply enough to build the right system.
1
Understand the operation
I map how the business actually works day to day, where time is lost and where the real bottlenecks are.
2
Design the architecture
I choose the smallest set of technologies that fit the problem and shape a system that can grow without rewrites.
3
Build the first working version
I ship a functional version fast, focused on proving value against real workflows rather than polishing demos.
4
Improve what survives real use
Once value is proven, I harden the parts that real users depend on and refine the architecture around them.

Working Style
I am problem-driven, not tool-driven.
I do not start from a framework or a trend. I start from the operational pain, identify the bottlenecks, choose the necessary tools and build the smallest working version that can prove value.
- 1
Choose technologies based on the problem, not on hype.
- 2
Build fast prototypes to validate the idea early.
- 3
Test with real business workflows, not synthetic demos.
- 4
Improve the architecture once the value is proven.
- 5
Turn rough ideas into reliable working systems.
