Freelancer profile translated to English.

Description

I design modern and high-performance web solutions. My vision of development goes beyond code: I focus on building robust, scalable, and production-ready architectures.

What I bring to your projects:

*Fullstackdevelopment: creating complete web applications, from the user interface to server logic.

DevOps and automation: mastery of containerization with Docker and infrastructure management through code (Terraform).

*Clouddeployment: ability to deploy and orchestrate services on AWS (ECS) to ensure high availability.

Rigor and adaptability: a structured approach to maintain, improve, or refactor existing codebases.

I transform your technical challenges into concrete and automated solutions!

Since the beginning of this year, I have been assisting companies in securing and industrializing their cloud platforms.
My approach combines Infrastructure as Code (Terraform), Zero Trust security, and performance optimization.

- **Legacy Migration to Containerization**: Complete transition of existing stacks (EC2/PM2) to managed architectures (AWS ECS Fargate or Scaleway Serverless Containers).
- **Identity-First Security**: Isolated multi-account governance, elimination of static credentials in favor of IAM OIDC, deployment of Secrets Manager, and migration of SSH access to AWS SSM Session Manager (zero open ports, complete CloudTrail audit).
- **Infrastructure as Code**: Design of robust and reusable Terraform modules (KMS, VPC, RDS, Aurora, ElastiCache, S3) with a DRY approach and multi-environment management (Staging/Production).
- **CI/CD**: Complete automation via GitHub Actions (branch mapping, force-redeploy via SHA tags, scoped environments) for smooth and error-free delivery.
- **No-Code Application Recovery**: Migration of applications generated with Lovable to self-hosted infrastructures (complete Supabase stack on Scaleway Serverless Containers).
- **PostgreSQL Performance**: Management of critical database migrations under constraints.
- **Observability**: Deployment of CloudWatch dashboards as code (ECS metrics, Container Insights, alerts) for proactive monitoring of application health.
