Back to original languageAbout Arthur
I structure cloud-native backend ecosystems, from design to production.
Backend developer trained at 42 Paris (architecture and low-level fundamentals), I am involved in the entire lifecycle: architectural design, data modeling, security, resilience, observability, and continuous deployment. My goal is to deliver robust, scalable, and maintainable platforms and to know how to operate them once in production, not just write them.
What sets me apart: a 2-year background in IT environments with direct client contact (portfolio of ~1,250 B2B/B2C accounts, needs qualification, project management up to acceptance). I quickly grasp business needs and transform them into concrete solutions without needing the challenges to be explained.
Some achievements:
- End-to-end design and development of distributed ecosystems (Symfony/Laravel REST APIs, APIP, React back-offices, mobile apps) deployed on Kubernetes in GitOps (ArgoCD), with Elasticsearch/Grafana/OpenTelemetry observability and CI/CD.
- Optimization of an educational content targeting model: +13% relevance of exercises delivered.
- Overhaul of a learner interface deployed in over 30,000 educational institutions.
How I work: audit of existing systems; stack design and structuring; development and deployment; transfer and maintenance in operational conditions.
Available for missions in Paris and remotely, in French or English, as part of a team or as reinforcement.
