About Me
Moises Santos is a Cloud Architect and Founder who speaks the language of both code and business. As the founder of CloudByFontos, he has spent over a decade delivering Platform Engineering and FinOps for global clients in AI, fintech, and gaming.
He understands that for a startup, "done is better than perfect"—but "secure and scalable" is non-negotiable. His expertise bridges the gap between rapid deployment and institutional-grade security, having navigated complex compliance landscapes (SOC2, PCI-DSS, ISO27001) for venture-backed companies.
From bootstrapping AI agents like carflipper.ai to optimizing infrastructure for major titles like NBA 2K, Moises builds the technical foundations that allow founders to focus on product, not parity. He has saved clients over $5.3M in cloud spend, proving that high-growth doesn't have to mean high-waste.
When he isn't engineering platforms, Moises invests in the next generation of talent, mentoring underrepresented developers to help them break into international engineering roles.
