Drupal & React developer

Renzo Emiliano Carletti

I upgrade legacy Drupal sites and connect them to React frontends.

I build and maintain Drupal sites for universities and government, and connect them to React and Vue frontends through REST, JSON:API and GraphQL. Most of my work is upgrading legacy Drupal projects, making them faster, and adding the features each user role needs. Before I write code, I talk with the people who use the system, so the result fits how they work.

Selected work

Live sites I built or worked on. Each one with the problem, what I did and the result.

  1. Home page of e-UADER

    Built end to end

    e-UADER

    UADER e-learning platform

    2,000+ users · 1,100+ certificates in 4 months

    Problem
    There was no single enrollment path. Each faculty enrolled students by hand, and digital certificates took a long time.
    What I did
    Connected Drupal Commerce to Moodle through its REST API, with a 5-step self-enrollment flow and automatic digital certificates.
    Result
    2,000+ registered users and 1,100+ certificates issued in its first 4 months, with no manual step to issue them.
  2. Home page of Ingresantes UADER

    Built end to end

    Ingresantes UADER

    Portal for prospective students

    4 faculties · 16 localities

    Problem
    Prospective students had no single place to find careers across 4 faculties and 16 localities, or to pre-enroll online.
    What I did
    Built a career finder in Drupal with pre-enrollment workflows, orientation tools and downloadable program guides.
    Result
    Applicants explore careers and start pre-enrollment in one guided place.
  3. Home page of Buenos Aires City

    Drupal consultant

    Buenos Aires City

    City government portal

    Problem
    A Drupal 8 codebase with scattered content and a Drupal 10 migration ahead.
    What I did
    Adapted content and Paragraphs for the Drupal 8 to 10 migration, fixed sync conflicts between both versions, and handled escalated incidents.
    Result
    Content moved to Drupal 10 with a cleaner model for editors.
  4. Home page of Club San Jorge

    Modernization

    Club San Jorge

    Legacy modernization

    Problem
    A legacy codebase with few conventions. Expensive to maintain and risky to change.
    What I did
    Refactored the project with modern patterns, a clearer structure and maintainable practices.
    Result
    Code the client can extend and maintain more easily.

Drupal, in practice

What I do in Drupal and where I did it.

Drupal 8, 9, 10 and 11

Upgrades and migrations
Drupal 8 to 10 content migration for the City of Buenos Aires. Legacy UADER sites upgraded for speed.
Custom modules and ECA
Custom modules, hooks and ECA automations that simplify each UADER area's workflows.
Content modeling
Paragraphs, Views and Entity API behind the Ingresantes career finder.
Headless Drupal
JSON:API and REST with OAuth2 feeding React at Activarte. A GraphQL move in progress at UADER.
Access and publishing
Role-based access and publishing rules in Drupal 10, the same in dev, staging and production.
Config and tooling
Configuration management with Composer, DDEV and Drush set up the same way in every environment.
Commerce and integrations
Drupal Commerce connected to Moodle's REST API for e-UADER enrollments and certificates.
Search, testing, performance
Search API for site search, PHPUnit for custom code, and fixes for server bottlenecks on UADER portals.
Decoupled Drupal
  1. Drupal CMS content model · RBAC · workflows
  2. JSON:API · OAuth2
  3. React frontend components · client routing

Editors keep publishing in Drupal while the React frontend ships on its own schedule. Each side deploys and scales separately.

AI in my workflow

Cursor and coding agents draft scaffolding, migrations and tests. For client and government code I use local models with Ollama. I review, refactor and test every change before it ships.
