Back to original languageAbout Liam
Symfony backend developer for five years
I have built business platforms for the public sector, SaaS, and a video web-app deployed during the Marathon des Sables.
Since January 2026, I have been working on a contract basis at Crédit Agricole de Champagne-Bourgogne, in a banking environment with GitLab CI/CD, ArgoCD, SonarQube, and Airflow.
Custom business applications
Symfony 7, API Platform, Doctrine, security, PHPUnit. Tools built to last and that the person taking over the project six months later can understand without a survival guide.
DevOps and infrastructure
Docker, Traefik, GitLab CI/CD, GitHub Actions, ArgoCD, SonarQube, Elastic/Kibana. I manage my own infra on Hetzner with Dokploy and Cloudflare, which makes me quickly operational in this area with a client.
Integrating AI into existing applications
Symfony AI Bundle, OpenAI, Anthropic, Mistral, self-hosted Ollama, RAG patterns, agents, MCP, n8n, Hermes Agents. I am not an AI consultant. I am a Symfony developer who knows how to properly integrate an LLM into a real business tool.
Front-end
Vue.js, Nuxt, Tailwind CSS when the mission requires fullstack.
I respond quickly, I document, I test. I ask business questions before coding.
Available for short or one-off missions.
