🤝 I'm Leonardo, your new
PRODUCT ARCHITECT
I design and build technical foundations for ambitious products.
About Me
I’m Leonardo, a Product Architect who bridges the gap between high-level vision and senior-level technical execution.
I believe that great software lives at the intersection of user experience and technical structure. When we work together, I translate your product vision into a robust technical foundation. I don’t just write code; I architect systems designed for growth, combining CTO-level strategy with the high-speed execution needed to get to market.
My approach is shaped by 7 years as the CTO and co-founder of Promoty, where I led a global product from inception to acquisition in 2024. I managed the full lifecycle: from architecting the initial MVP to scaling a platform used worldwide and raising €1.8M in funding. Today, I partner with ambitious founders to turn their ideas into high-performing, production-ready products.
My Services
Fractional CTO & Architecture
I become the architect of your technical foundation and your single point of contact for the entire product lifecycle. I guide high-level decisions, translate product goals into architectural requirements, and ensure your tech stack is built to scale from day one. Ideal for founders who need senior technical leadership without the full-time overhead.
End-to-End Product Development
I build production-ready digital products and internal platforms from the first wireframe to the final deployment. My focus is on high-speed execution without sacrificing structural integrity. Whether you're validating a new idea or building an enterprise-grade tool, I deliver the code and the strategy needed to launch successfully.
System Modernization & Scaling
I transform fragile, legacy infrastructures into modern, scalable engines. If your current system is slowing down your product growth, I re-architect and migrate your stack to ensure it's easy to manage and ready for global traffic. I turn technical debt into a competitive advantage.

CEO @ PromotyI've worked with Leonardo since 2020, when we needed to take our fitness services online. Leonardo delivered an outstanding solution with Wellnet. He is more than just a developer—he understands business, branding, and user experience. When we launched Wellnet in 2020, his insights helped us create not just a platform but a valuable extension of our fitness brand. I can highly recommend his services!
