About Jawhar
I help SaaS companies design, migrate, and operate reliable AWS infrastructure using Terraform and modern DevOps practices.
I specialize in production environments where stability, security, and automation matter — including infrastructure refactoring, database migrations, and CI/CD pipelines.
What I can help you with:
- AWS infrastructure setup & optimization (VPC, IAM, EC2, EKS, RDS)
- Terraform infrastructure as code (new modules, refactoring, best practices)
- Database migrations & upgrades (MySQL)
- CI/CD pipelines and release automation (GitHub Actions)
I’m used to working with distributed teams and communicating asynchronously. I focus on clear deliverables, pragmatic solutions, and long-term maintainability.
Available part-time (evenings & weekends), remote-first.
