Hi, I'm Marco Oliveira.
I have spent the last decade building and scaling software systems for startups and high-growth companies. Throughout my career, I've seen how often great ideas fail because of preventable technical mistakes such as poor architecture, rushed MVPs, or unclear strategy.
That experience inspired me to create WelloDev to help founders and investors make smarter technical decisions early. I focus on creating strong technical foundations, improving scalability, and reducing risk.
