Migrating an app from Symfony 5 to Symfony 7, with all its dependencies, added testing , fixed some bugs with automated test generation, and coaching on new coding practices.

Maintenance of a very old legacy PHP app, re-architecturing, audit of current state and usage of the project, fixes in old practices, help in upgrading PHP version, helping juniors/med devs learn about more advanced coding practices

Development on PHP/Symfony and Angular apps, with GraphQL, DDD, CI/CD,
Event Sourcing and Ansible.
Project 1: a big GraphQL API serving an Angular frontend app, mostly being
a custom administration panel, for a country-wise product system in the wine
industry, events organization and big rules and processes to define products
attributes.
Project 2 : a big events management system built with a GraphQL API
serving an angular frontend app, similar to the previous one, but this time also powered by EventSourcing for some data, contacts management, rules, and
events planning.

Modernize the GLPI project, a 20+ years-old Open Source PHP application, by standardizing some processes, updating the code architecture to a more modern stack, and refactor old code into new systems and structures, while keeping compatibility as much as possible with older tools and plugins.

Coordinate the modernization, refactoring and rewrite of very old legacy
applications into more robust and modern infrastructure.
Case one:
An old PHP-from-scratch app with a Java-based map application.
Rewriting it into this:

• A Svelte+OpenLayers-based frontend, with an integration of legacy views
  and pages, flexible enough to be selectively rewritten into new Svelte+API
  components
• Geoserver instance for cartography data
• PHP/Symfony new backend application with EasyAdmin as administration
  panel and Api Platform as data gateway for environments, user permissions
  and main workspace data
  Case two:
  An old Microsoft PowerBuilder application with really big MySQL database as
  backend.
  Rewriting into this:
• A SvelteKit administration panel as frontend, connecting to an API using an
  OpenAPI-generated HTTP client, had to redevelop an Open Source admin
  system to fit the needs, and used IBM's Carbon Design System.
• PHP/Symfony backend with Api Platform-generated resources, with
  DDD/Clean architecture, lots of functional testing and configuration setup,
  connecting to the legacy database and exposing a more modern version of the
  legacy schema.

Maintenance of a PHP/Symfony application with some DDD practices.
Creation of a Rust+Tauri+Vue cross-platform desktop application.

Architecture, maintenance and functional-testing of a big PHP/Symfony
application serving a big GraphQL API for Next.js/React frontends.

Case study:
A big PHP/Symfony ecommerce/ERP white-labeled application that is copy/
pasted to all clients.
The mission was to update it to a single-package application which
development can be centralized, to ease updates and customization for
clients, and lower the pain of backporting bugs to "older" clients projects.
Basically, convert a "copy-paste template app" into a "composer require brand/
core-app" behavior.
