About this gig

Senior software developer running INTEA, a boutique agency delivering fast, secure, framework-free custom software. If you need business logic built, not just a template configured, this is the gig for you.


What I build:

  • Custom backend modules and business logic (PHP/MySQL)
  • - Workflow automation replacing manual spreadsheet/email processes
  • - Database design and data migrations
  • - Admin tooling for internal teams

Why custom over off-the-shelf: rigid SaaS tools force your business to adapt to their workflow. I build software that matches how you work, with clean code you fully own.


Background: systems ranging from HR consultancy platforms to industrial inventory tools to multi-tenant SaaS with document automation. Security-first (OWASP, prepared statements), built to be maintained by any developer after delivery.


Message me with your workflow before ordering so I can scope it accurately.

Senior software developer & technical architect (Argentina), working through INTEA. I build fast, secure, framework-free PHP apps — from corporate sites to multi-tenant SaaS platforms — plus custom AI knowledge assistants (MCP) trained on a business's own documentation, not generic chatbot wrappers. Also technical SEO/GEO: Schema.org, EEAT, optimizing sites for AI search engines like ChatGPT and Perplexity. I favor lean, dependency-free code over heavy frameworks. Fluent in Spanish and English, comfortable working async.
