I build and scale cloud-native full-stack SaaS and enterprise applications.
ArgentinaWhat I'm looking for
I've architected and scaled production SaaS, enterprise, and cloud-native applications end to end for Vertex AI Systems, NorthPeak Software, and Innovatech Solutions. At Vertex AI Systems, I built React/Next.js applications with Python/FastAPI and Node.js microservices, AI-powered features, REST and GraphQL APIs, and AWS/Azure infrastructure automation.
Over 10+ years, I've delivered full-stack solutions from frontend to infrastructure, optimized databases and asynchronous workflows, modernized legacy applications, and improved delivery through Docker, Kubernetes, Terraform, CI/CD, testing, and reusable architecture patterns. I own technical decisions end to end, mentor engineers, and work with product and business stakeholders to ship on schedule.
