What People Say
Real feedback from clients, colleagues, and collaborators I've worked with on AI systems, full-stack products, and everything in between.

“The MILA RAG assistant shipped with proper evals and citations. Clinicians trusted it because the UX was measured.”

Chief Medical Officer, Hospital Materno Infantil José Domingo de Obaldía
“Osvaldo doesn't just write code — he understands the architecture behind the business problem. He ramped up fast, asked the right questions, and delivered production-grade AI features that our clients actually use. Hard to find that combination.”

Chief Technology Officer, TheGreyMatter.ai
“We needed someone who could bridge the gap between what AI can do and what the business actually needs. Osvaldo did exactly that — shipped fast, communicated clearly, and built systems that scaled without drama.”
