— Work
I work with Next.js, Node.js, React and PostgreSQL in the public sector and freelance projects: web products, APIs, sensitive data and legacy system modernization.
- Method
- I work with AI agents, adopted gradually and with judgment. I am always the human in the loop: tests of every kind, constant cross-reviews, and human approval, always.
- Education
- I hold a university degree in Computer Systems Analysis from Universidad Siglo 21 and am currently pursuing a degree in Computer Science.
~20 years age of the legacy system
Plate 01 Legacy B2B
Client confidential
Modernize without replacing.
A B2B product that coexists with a C# / .NET application and a legacy system approximately 20 years old.
New Next.js · Node.js · PostgreSQL
Already there C# / .NET · legacy system
The web side is Next.js, Node.js and PostgreSQL. Full compatibility, workarounds included, is part of the scope: modernizing without requiring the legacy application to be replaced first.
AI → person
Plate 02 Catalog
Client confidential
Catalog, inquiries, and a person when needed.
A catalog e-commerce site: it presents products and handles customer inquiries, with no payment gateway. Next.js for the web, PostgreSQL for the data.
Support starts with AI (Vercel AI SDK) and hands off to a person when human intervention is needed.
No client name, screenshots or code. Confidential, not mysterious.
