Profile
Writing code since 2021, I've shipped products end-to-end across multiple verticals — APIs, backend logic,
databases, and the automation around them. I think at the architecture level first: understand the constraint,
weigh the tradeoffs, then execute. Today my focus is the data side of engineering: Python for data work, cloud
infrastructure on AWS, and AI-powered workflows.
Skills
Languages: Python, Java, SQL, TypeScript, C#
Backend & data: REST APIs, FastAPI, Node.js, PostgreSQL, data pipelines, n8n, Supabase
Cloud & DevOps: AWS, Azure, Docker, Kubernetes, CI/CD (GitHub, Azure DevOps), Git
Spoken languages: Spanish (native), Portuguese (native), English (professional), German (improving)
